text: Following the defeat of Nazi Germany in World War II, the Soviet Union engineered the installation of Communist governments in most of the countries occupied by Soviet military forces at the end of the War, including Poland, Hungary, Czechoslovakia, Bulgaria, Romania, and the GDR, which together with Albania formed the Comecon in 1949 and later a military alliance, the Warsaw Pact. This bloc of nations was set up by the Soviets in opposition to NATO in the capitalist West in what became the Cold War.


title: Berlin Wall

text: Since the end of the War, the Soviets together with like-minded East Germans created a new Soviet-style regime in the Soviet Zone and later the GDR, on a centrally planned socialist economic model with nationalized means of production, and with repressive police state institutions, under party dictatorship of the SED (Sozialistische Einheitspartei Deutschlands; Socialist Unity Party of Germany) similar to the party dictatorship of the Soviet Communist Party in the USSR.


title: Berlin Wall

text: At the same time, a parallel regime was established under the strict control of the Western powers in the zones of post-war Germany occupied by them, culminating in the foundation of the Federal Republic of Germany in 1949, which initially claimed to be the sole legitimate power in all of Germany, East and West. The material standard of living in the Western zones of Berlin began to improve quickly, and residents of the Soviet Zone soon began leaving for the West in large numbers, fleeing hunger, poverty and repression in the Soviet Zone for a better life in the West. Soon residents of other parts of the Soviet Zone began to escape to the West through Berlin, and this migration, called in Germany "Republikflucht", deprived the Soviet Zone not only of working forces desperately needed for post-war reconstruction but disproportionately highly educated people, which came to be known as the "Brain Drain".


title: Berlin Wall

text: In 1948, in response to moves by the Western powers to establish a separate, federal system of government in the Western zones, and to extend the Marshall Plan to Germany, the Soviets instituted the Berlin Blockade, preventing people, food, materials and supplies from arriving in West Berlin by land routes through the Soviet zone. The United States, the United Kingdom, France, Canada, Australia, New Zealand and several other countries began a massive "airlift", supplying West Berlin with food and other supplies. The Soviets mounted a public relations campaign against the Western policy change. Communists attempted to disrupt the elections of 1948, preceding large losses therein, while 300,000 Berliners demonstrated for the international airlift to continue. In May 1949, Stalin lifted the blockade, permitting the resumption of Western shipments to Berlin.


title: Berlin Wall

text: The German Democratic Republic (the "GDR"; East Germany) was declared on 7 October 1949. On that day, the USSR ended the Soviet military government which had governed the Soviet Occupation Zone (Sowetische Besatzungszone) since the end of the War and handed over legal power to the Provisorische Volkskammer under the new Constitution of the GDR which came into force that day. However, until 1955, the Soviets maintained considerable legal control over the GDR state, including the regional governments, through the Sowetische Kontrollkommission and maintained a presence in various East German administrative, military, and secret police structures. Even after legal sovereignty of the GDR was restored in 1955, the Soviet Union continued to maintain considerable influence over administration and lawmaking in the GDR through the Soviet embassy and through the implicit threat of force which could be exercised through the continuing large Soviet military presence in the GDR, which was used to repress protests in East Germany bloodily in June 1953.


title: Berlin Wall

text: East Germany differed from West Germany (Federal Republic of Germany), which developed into a Western capitalist country with a social market economy and a democratic parliamentary government. Continual economic growth starting in the 1950s fueled a 20-year "economic miracle" (). As West Germany's economy grew, and its standard of living steadily improved, many East Germans wanted to move to West Germany.


title: Berlin Wall

text: After the Soviet occupation of Eastern Europe at the end of World War II, the majority of those living in the newly acquired areas of the Eastern Bloc aspired to independence and wanted the Soviets to leave. Taking advantage of the zonal border between occupied zones in Germany, the number of GDR citizens moving to West Germany totaled 187,000 in 1950; 165,000 in 1951; 182,000 in 1952; and 331,000 in 1953. One reason for the sharp 1953 increase was fear of potential further Sovietization, given the increasingly paranoid actions of Joseph Stalin in late 1952 and early 1953. In the first six months of 1953, 226,000 had fled.


title: Berlin Wall

text: By the early 1950s, the Soviet approach to controlling national movement, restricting emigration, was emulated by most of the rest of the Eastern Bloc, including East Germany. The restrictions presented a quandary for some Eastern Bloc states, which had been more economically advanced and open than the Soviet Union, such that crossing borders seemed more natural—especially where no prior border existed between East and West Germany.


title: Berlin Wall

text: Up until 1952, the demarcation lines between East Germany and the western occupied zones could be easily crossed in most places. On 1 April 1952, East German leaders met the Soviet leader Joseph Stalin in Moscow; during the discussions, Stalin's foreign minister Vyacheslav Molotov proposed that the East Germans should "introduce a system of passes for visits of West Berlin residents to the territory of East Berlin [so as to stop] free movement of Western agents" in the GDR. Stalin agreed, calling the situation "intolerable". He advised the East Germans to build up their border defenses, telling them that "The demarcation line between East and West Germany should be considered a border—and not just any border, but a dangerous one ... The Germans will guard the line of defence with their lives."


title: Berlin Wall

text: Consequently, the inner German border between the two German states was closed, and a barbed-wire fence erected. The border between the Western and Eastern sectors of Berlin, however, remained open, although traffic between the Soviet and the Western sectors was somewhat restricted. This resulted in Berlin becoming a magnet for East Germans desperate to escape life in the GDR, and also a flashpoint for tension between the United States and the Soviet Union.


title: Berlin Wall

text: In 1955, the Soviets gave East Germany authority over civilian movement in Berlin, passing control to a regime not recognized in the West. Initially, East Germany granted "visits" to allow its residents access to West Germany. However, following the defection of large numbers of East Germans (known as "Republikflucht") under this regime, the new East German state legally restricted virtually all travel to the West in 1956. Soviet East German ambassador Mikhail Pervukhin observed that "the presence in Berlin of an open and essentially uncontrolled border between the socialist and capitalist worlds unwittingly prompts the population to make a comparison between both parts of the city, which unfortunately does not always turn out in favour of Democratic [East] Berlin."


title: Berlin Wall

text: With the closing of the inner German border officially in 1952, the border in Berlin remained considerably more accessible because it was administered by all four occupying powers. Accordingly, Berlin became the main route by which East Germans left for the West. On 11 December 1957, East Germany introduced a new passport law that reduced the overall number of refugees leaving Eastern Germany.


title: Berlin Wall

text: It had the unintended result of drastically increasing the percentage of those leaving through West Berlin from 60% to well over 90% by the end of 1958. Those caught trying to leave East Berlin were subjected to heavy penalties, but with no physical barrier and subway train access still available to West Berlin, such measures were ineffective. The Berlin sector border was essentially a "loophole" through which Eastern Bloc citizens could still escape. The 3.5 million East Germans who had left by 1961 totalled approximately 20% of the entire East German population.


title: Berlin Wall

text: An important reason that passage between East Germany and West Berlin was not stopped earlier was that doing so would cut off much of the railway traffic in East Germany. Construction of a new railway bypassing West Berlin, the Berlin outer ring, commenced in 1951. Following the completion of the railway in 1961, closing the border became a more practical proposition.


title: Berlin Wall

text: The emigrants tended to be young and well-educated, leading to the "brain drain" feared by officials in East Germany. Yuri Andropov, then the CPSU Director on Relations with Communist and Workers' Parties of Socialist Countries, wrote an urgent letter on 28 August 1958 to the Central Committee about the significant 50% increase in the number of East German intelligentsia among the refugees. Andropov reported that, while the East German leadership stated that they were leaving for economic reasons, testimony from refugees indicated that the reasons were more political than material. He stated "the flight of the intelligentsia has reached a particularly critical phase."


title: Berlin Wall

text: By 1960, the combination of World War II and the massive emigration westward left East Germany with only 61% of its population of working age, compared to 70.5% before the war. The loss was disproportionately heavy among professionals: engineers, technicians, physicians, teachers, lawyers, and skilled workers. The direct cost of manpower losses to East Germany (and corresponding gain to the West) has been estimated at $7 billion to $9 billion, with East German party leader Walter Ulbricht later claiming that West Germany owed him $17 billion in compensation, including reparations as well as manpower losses. In addition, the drain of East Germany's young population potentially cost it over 22.5 billion marks in lost educational investment. The brain drain of professionals had become so damaging to the political credibility and economic viability of East Germany that the re-securing of the German communist frontier was imperative.


title: Berlin Wall

text: The exodus of emigrants from East Germany presented two minor potential benefits: an easy way to smuggle East German secret agents to West Germany, and a reduction in the number of citizens hostile to the communist regime. Neither of these advantages, however, proved particularly useful.


title: Berlin Wall

text: On 15 June 1961, First Secretary of the Socialist Unity Party and GDR State Council chairman Walter Ulbricht stated in an international press conference, (No one has the intention of erecting a wall!). It was the first time the colloquial term (wall) had been used in this context.


title: Berlin Wall

text: The transcript of a telephone call between Nikita Khrushchev and Ulbricht, on 1 August in the same year, suggests that the initiative for the construction of the Wall came from Khrushchev. However, other sources suggest that Khrushchev had initially been wary about building a wall, fearing negative Western reaction. Nevertheless, Ulbricht had pushed for a border closure for some time, arguing that East Germany's existence was at stake.


title: Berlin Wall

text: Khrushchev had become emboldened upon seeing US president John F. Kennedy's youth and inexperience, which he considered a weakness. In the 1961 Vienna summit, Kennedy made the error of admitting that the US wouldn't actively oppose the building of a barrier. A feeling of miscalculation and failure immediately afterwards was admitted by Kennedy in a candid interview with "New York Times" columnist James "Scotty" Reston. On Saturday, 12 August 1961, the leaders of the GDR attended a garden party at a government guesthouse in , in a wooded area to the north of East Berlin. There, Ulbricht signed the order to close the border and erect a wall.


title: Berlin Wall

text: At midnight, the police and units of the East German army began to close the border and, by Sunday morning, 13 August, the border with West Berlin was closed. East German troops and workers had begun to tear up streets running alongside the border to make them impassable to most vehicles and to install barbed wire entanglements and fences along the around the three western sectors, and the that divided West and East Berlin. The date of 13 August became commonly referred to as Barbed Wire Sunday in Germany.


title: Berlin Wall

text: The barrier was built inside East Berlin on East German territory to ensure that it did not encroach on West Berlin at any point. Generally, the Wall was only slightly inside East Berlin, but in a few places it was some distance from the legal border, most notably at Potsdamer Bahnhof and the Lenné Triangle that is now much of the Potsdamer Platz development.


title: Berlin Wall

text: Later, the initial barrier was built up into the Wall proper, the first concrete elements and large blocks being put in place on 17 August. During the construction of the Wall, National People's Army (NVA) and Combat Groups of the Working Class (KdA) soldiers stood in front of it with orders to shoot anyone who attempted to defect. Additionally, chain fences, walls, minefields and other obstacles were installed along the length of East Germany's western border with West Germany proper. A huge no man's land was cleared to provide a clear line of fire at fleeing refugees.


title: Berlin Wall

text: With the closing of the east–west sector boundary in Berlin, the vast majority of East Germans could no longer travel or emigrate to West Germany. Berlin soon went from being the easiest place to make an unauthorized crossing between East and West Germany to being the most difficult. Many families were split, while East Berliners employed in the West were cut off from their jobs. West Berlin became an isolated exclave in a hostile land. West Berliners demonstrated against the Wall, led by their Mayor () Willy Brandt, who criticized the United States for failing to respond and went so far as to suggest to Washington what to do next. Kennedy was furious. Allied intelligence agencies had hypothesized about a wall to stop the flood of refugees, but the main candidate for its location was around the perimeter of the city. In 1961, Secretary of State Dean Rusk proclaimed, "The Wall certainly ought not to be a permanent feature of the European landscape. I see no reason why the Soviet Union should think it is—it is to their advantage in any way to leave there that monument to communist failure."


title: Berlin Wall

text: United States and UK sources had expected the Soviet sector to be sealed off from West Berlin but were surprised by how long the East Germans took for such a move. They considered the Wall as an end to concerns about a GDR/Soviet retaking or capture of the whole of Berlin; the Wall would presumably have been an unnecessary project if such plans were afloat. Thus, they concluded that the possibility of a Soviet military conflict over Berlin had decreased.


title: Berlin Wall

text: The East German government claimed that the Wall was an "anti-fascist protective rampart" () intended to dissuade aggression from the West. Another official justification was the activities of Western agents in Eastern Europe. The Eastern German government also claimed that West Berliners were buying out state-subsidized goods in East Berlin. East Germans and others greeted such statements with skepticism, as most of the time, the border was only closed for citizens of East Germany traveling to the West, but not for residents of West Berlin travelling to the East. The construction of the Wall had caused considerable hardship to families divided by it. Most people believed that the Wall was mainly a means of preventing the citizens of East Germany from entering or fleeing to West Berlin.


title: Berlin Wall

text: The National Security Agency was the only American intelligence agency that was aware that East Germany was to take action to deal with the brain drain problem. On 9 August 1961, the NSA intercepted an advance warning information of the Socialist Unity Party's plan to close the intra-Berlin border between East and West Berlin completely for foot traffic. The interagency intelligence Berlin Watch Committee assessed that this intercept "might be the first step in a plan to close the border." This warning did not reach John F. Kennedy until noon on 13 August 1961, while he was vacationing in his yacht off the Kennedy Compound in Hyannis Port, Massachusetts. While Kennedy was angry that he had no advance warning, he was relieved that the East Germans and the Soviets had only divided Berlin without taking any action against West Berlin's access to the West. However, he denounced the Berlin Wall, whose erection worsened the relations between the United States and the Soviet Union.


title: Berlin Wall

text: In response to the erection of the Berlin Wall, a retired general, Lucius D. Clay, was appointed by Kennedy as his special advisor with ambassadorial rank. Clay had been the Military Governor of the US Zone of Occupation in Germany during the period of the Berlin Blockade and had ordered the first measures in what became the Berlin Airlift. He was immensely popular with the residents of West Berlin, and his appointment was an unambiguous sign that Kennedy would not compromise on the status of West Berlin. As a symbolic gesture, Kennedy sent Clay and Vice President Lyndon B. Johnson to West Berlin. They landed at Tempelhof Airport on the afternoon of Saturday, 19 August 1961 and were greeted enthusiastically by the local population.


title: Berlin Wall

text: They arrived in a city defended by three Allied brigades—one each from the UK (Berlin Infantry Brigade), the US (Berlin Brigade), and France (Forces Françaises à Berlin). On 16 August, Kennedy had given the order for them to be reinforced. Early on 19 August, the 1st Battle Group, 18th Infantry Regiment (commanded by Colonel Glover S. Johns Jr.) was alerted.


title: Berlin Wall

text: On Sunday morning, U.S. troops marched from West Germany through East Germany, bound for West Berlin. Lead elements—arranged in a column of 491 vehicles and trailers carrying 1,500 men, divided into five march units—left the Helmstedt-Marienborn checkpoint at 06:34. At Marienborn, the Soviet checkpoint next to Helmstedt on the West German-East German border, US personnel were counted by guards. The column was long, and covered from Marienborn to Berlin in full battle gear. East German police watched from beside trees next to the autobahn all the way along.


title: Berlin Wall

text: The front of the convoy arrived at the outskirts of Berlin just before noon, to be met by Clay and Johnson, before parading through the streets of Berlin in front of a large crowd. At 04:00 on 21 August, Lyndon Johnson left West Berlin in the hands of General Frederick O. Hartel and his brigade of 4,224 officers and men. "For the next three and a half years, American battalions would rotate into West Berlin, by autobahn, at three-month intervals to demonstrate Allied rights to the city".


title: Berlin Wall

text: The creation of the Wall had important implications for both German states. By stemming the exodus of people from East Germany, the East German government was able to reassert its control over the country: in spite of discontent with the Wall, economic problems caused by dual currency and the black market were largely eliminated. The economy in the GDR began to grow. However, the Wall proved a public relations disaster for the communist bloc as a whole. Western powers portrayed it as a symbol of communist tyranny, particularly after East German border guards shot and killed would-be defectors. Such fatalities were later treated as acts of murder by the reunified Germany.


title: Berlin Wall

text: The Berlin Wall was more than long. In June 1962, a second, parallel fence, also known as a "hinterland" wall (inner wall), was built some farther into East German territory. The houses contained between the wall and fences were razed and the inhabitants relocated, thus establishing what later became known as the "death strip". The death strip was covered with raked sand or gravel, rendering footprints easy to notice, easing the detection of trespassers and also enabling officers to see which guards had neglected their task; it offered no cover; and, most importantly, it offered clear fields of fire for the Wall guards.


title: Berlin Wall

text: The "fourth-generation Wall", known officially as "" (retaining wall element UL 12.11), was the final and most sophisticated version of the Wall. Begun in 1975 and completed about 1980, it was constructed from 45,000 separate sections of reinforced concrete, each high and wide, and cost DDM16,155,000 or about US$3,638,000. The concrete provisions added to this version of the Wall were done to prevent escapees from driving their cars through the barricades. At strategic points, the Wall was constructed to a somewhat weaker standard, so that East German and Soviet armored vehicles could easily break through in the event of war.


title: Berlin Wall

text: The top of the wall was lined with a smooth pipe, intended to make it more difficult to scale. The Wall was reinforced by mesh fencing, signal fencing, anti-vehicle trenches, barbed wire, dogs on long lines, "beds of nails" (also known as "Stalin's Carpet") under balconies hanging over the "death strip", over 116 watchtowers, and 20 bunkers with hundreds of guards. This version of the Wall is the one most commonly seen in photographs, and surviving fragments of the Wall in Berlin and elsewhere around the world are generally pieces of the fourth-generation Wall. The layout came to resemble the inner German border in most technical aspects, except that the Berlin Wall had no landmines nor spring-guns. Maintenance was performed on the outside of the wall by personnel who accessed the area outside it either via ladders or via hidden doors within the wall. These doors could not be opened by a single person, needing two separate keys in two separate keyholes to unlock.


title: Berlin Wall

text: As was the case with the inner German border, an unfortified strip of Eastern territory was left outside the wall. This outer strip was used by workers to paint over graffiti and perform other maintenance on the outside of the wall Unlike the inner German border, however, the outer strip was usually no more than four meters wide, and, in photos from the era, the exact location of the actual border in many places appears not even to have been marked. Also in contrast with the inner German border, little interest was shown by East German law enforcement in keeping outsiders off the outer strip; sidewalks of West Berlin streets even ran inside it.


title: Berlin Wall

text: Despite the East German government's general policy of benign neglect, vandals were known to have been pursued in the outer strip, and even arrested. In 1986, defector and political activist Wolfram Hasch and four other defectors were standing inside the outer strip defacing the wall when East German personnel emerged from one of the hidden doors to apprehend them. All but Hasch escaped back into the western sector. Hasch himself was arrested, dragged through the door into the death strip, and later convicted of illegally crossing the "de jure" border outside the wall. Graffiti artist Thierry Noir has reported having often been pursued there by East German soldiers. While some graffiti artists were chased off the outer strip, others, such as Keith Haring, were seemingly tolerated.


title: Berlin Wall

text: Besides the sector-sector boundary within Berlin itself, the Wall also separated West Berlin from the present-day state of Brandenburg. The following present-day municipalities, listed in counter-clockwise direction, share a border with the former West Berlin:


title: Berlin Wall

text: There were nine border crossings between East and West Berlin. These allowed visits by West Berliners, other West Germans, Western foreigners and Allied personnel into East Berlin, as well as visits by GDR citizens and citizens of other socialist countries into West Berlin, provided that they held the necessary permits. These crossings were restricted according to which nationality was allowed to use it (East Germans, West Germans, West Berliners, other countries). The best known was the vehicle and pedestrian checkpoint at the corner of Friedrichstraße and Zimmerstraße (Checkpoint Charlie), which was restricted to Allied personnel and foreigners.


title: Berlin Wall

text: Several other border crossings existed between West Berlin and surrounding East Germany. These could be used for transit between West Germany and West Berlin, for visits by West Berliners into East Germany, for transit into countries neighbouring East Germany (Poland, Czechoslovakia, Denmark), and for visits by East Germans into West Berlin carrying a permit. After the 1972 agreements, new crossings were opened to allow West Berlin waste to be transported into East German dumps, as well as some crossings for access to West Berlin's exclaves (see "Steinstücken").


title: Berlin Wall

text: Four autobahns connected West Berlin to West Germany, including Berlin-Helmstedt autobahn, which entered East German territory between the towns of Helmstedt and Marienborn (Checkpoint Alpha), and which entered West Berlin at Dreilinden (Checkpoint Bravo for the Allied forces) in southwestern Berlin. Access to West Berlin was also possible by railway (four routes) and by boat for commercial shipping via canals and rivers.


title: Berlin Wall

text: Non-German Westerners could cross the border at Friedrichstraße station in East Berlin and at Checkpoint Charlie. When the Wall was erected, Berlin's complex public transit networks, the S-Bahn and U-Bahn, were divided with it. Some lines were cut in half; many stations were shut down. Three western lines traveled through brief sections of East Berlin territory, passing through eastern stations (called "", or ghost stations) without stopping. Both the eastern and western networks converged at , which became a major crossing point for those (mostly Westerners) with permission to cross.


title: Berlin Wall

text: West Germans and citizens of other Western countries could generally visit East Germany, often after applying for a visa at an East German embassy several weeks in advance. Visas for day trips restricted to East Berlin were issued without previous application in a simplified procedure at the border crossing. However, East German authorities could refuse entry permits without stating a reason. In the 1980s, visitors from the western part of the city who wanted to visit the eastern part had to exchange at least DM 25 into East German currency at the poor exchange rate of 1:1. It was forbidden to export East German currency from the East, but money not spent could be left at the border for possible future visits. Tourists crossing from the west had to also pay for a visa, which cost DM 5; West Berliners did not have to pay this fee.


title: Berlin Wall

text: West Berliners initially could not visit East Berlin or East Germany at all—all crossing points were closed to them between 26 August 1961 and 17 December 1963. In 1963, negotiations between East and West resulted in a limited possibility for visits during the Christmas season that year (). Similar, very limited arrangements were made in 1964, 1965 and 1966.


title: Berlin Wall

text: In 1971, with the Four Power Agreement on Berlin, agreements were reached that allowed West Berliners to apply for visas to enter East Berlin and East Germany regularly, comparable to the regulations already in force for West Germans. However, East German authorities could still refuse entry permits.


title: Berlin Wall

text: East Berliners and East Germans could not, at first, travel to West Berlin or West Germany at all. This regulation remained in force essentially until the fall of the Wall, but over the years several exceptions to these rules were introduced, the most significant being:


title: Berlin Wall

text: For each of these exceptions, GDR citizens had to apply for individual approval, which was never guaranteed. In addition, even if travel was approved, GDR travellers could exchange only a very small amount of East German Marks into Deutsche Marks (DM), thus limiting the financial resources available for them to travel to the West. This led to the West German practice of granting a small amount of DM annually ("Begrüßungsgeld", or welcome money) to GDR citizens visiting West Germany and West Berlin to help alleviate this situation.


title: Berlin Wall

text: Citizens of other East European countries were in general subject to the same prohibition of visiting Western countries as East Germans, though the applicable exception (if any) varied from country to country.


title: Berlin Wall

text: Allied military personnel and civilian officials of the Allied forces could enter and exit East Berlin without submitting to East German passport controls, purchasing a visa or being required to exchange money. Likewise, Soviet military patrols could enter and exit West Berlin. This was a requirement of the post-war Four Powers Agreements. A particular area of concern for the Western Allies involved official dealings with East German authorities when crossing the border, since Allied policy did not recognize the authority of the GDR to regulate Allied military traffic to and from West Berlin, as well as the Allied presence within Greater Berlin, including entry into, exit from, and presence within East Berlin.


title: Berlin Wall

text: The Allies held that only the Soviet Union, and not the GDR, had the authority to regulate Allied personnel in such cases. For this reason, elaborate procedures were established to prevent inadvertent recognition of East German authority when engaged in travel through the GDR and when in East Berlin. Special rules applied to travel by Western Allied military personnel assigned to the military liaison missions accredited to the commander of Soviet forces in East Germany, located in Potsdam.


title: Berlin Wall

text: As with military personnel, special procedures applied to travel by diplomatic personnel of the Western Allies accredited to their respective embassies in the GDR. This was intended to prevent inadvertent recognition of East German authority when crossing between East and West Berlin, which could jeopardize the overall Allied position governing the freedom of movement by Allied forces personnel within all Berlin.


title: Berlin Wall

text: Ordinary citizens of the Western Allied powers, not formally affiliated with the Allied forces, were authorized to use all designated transit routes through East Germany to and from West Berlin. Regarding travel to East Berlin, such persons could also use the Friedrichstraße train station to enter and exit the city, in addition to Checkpoint Charlie. In these instances, such travelers, unlike Allied personnel, had to submit to East German border controls.


title: Berlin Wall

text: During the years of the Wall, around 5,000 people successfully defected to West Berlin. The number of people who died trying to cross the Wall, or as a result of the Wall's existence, has been disputed. The most vocal claims by Alexandra Hildebrandt, Director of the Checkpoint Charlie Museum and widow of the Museum's founder, estimated the death toll to be well above 200. A historic research group at the Centre for Contemporary History (ZZF) in Potsdam has confirmed at least 140 deaths. Prior official figures listed 98 as being killed.


title: Berlin Wall

text: The East German government issued shooting orders ("Schießbefehl") to border guards dealing with defectors, though such orders are not the same as "shoot to kill" orders. GDR officials denied issuing the latter. In an October 1973 order later discovered by researchers, guards were instructed that people attempting to cross the Wall were criminals and needed to be shot:


title: Berlin Wall

text: Early successful escapes involved people jumping the initial barbed wire or leaping out of apartment windows along the line, but these ended as the Wall was fortified. East German authorities no longer permitted apartments near the Wall to be occupied, and any building near the Wall had its windows boarded and later bricked up. On 15 August 1961, Conrad Schumann was the first East German border guard to escape by jumping the barbed wire to West Berlin.


title: Berlin Wall

text: On 22 August 1961, Ida Siekmann was the first casualty at the Berlin Wall: she died after she jumped out of her third floor apartment at 48 Bernauer Strasse. The first person to be shot and killed while trying to cross to West Berlin was Günter Litfin, a twenty-four-year-old tailor. He attempted to swim across the Spree to West Berlin on 24 August 1961, the same day that East German police had received shoot-to-kill orders to prevent anyone from escaping.


title: Berlin Wall

text: Another dramatic escape was carried out in April 1963 by Wolfgang Engels, a 19-year-old civilian employee of the "Nationale Volksarmee" (NVA). Engels stole a Soviet armored personnel carrier from a base where he was deployed and drove it right into the Wall. He was fired at and seriously wounded by border guards. But a West German policeman intervened, firing his weapon at the East German border guards. The policeman removed Engels from the vehicle, which had become entangled in the barbed wire.


title: Berlin Wall

text: East Germans successfully defected by a variety of methods: digging long tunnels under the Wall, waiting for favorable winds and taking a hot air balloon, sliding along aerial wires, flying ultralights and, in one instance, simply driving a sports car at full speed through the basic, initial fortifications. When a metal beam was placed at checkpoints to prevent this kind of defection, up to four people (two in the front seats and possibly two in the boot) drove under the bar in a sports car that had been modified to allow the roof and windscreen to come away when it made contact with the beam. They lay flat and kept driving forward. The East Germans then built zig-zagging roads at checkpoints. The sewer system predated the Wall, and some people escaped through the sewers, in a number of cases with assistance from the Unternehmen Reisebüro. In September 1962, 29 people escaped through a tunnel to the west. At least 70 tunnels were dug under the wall; only 19 were successful in allowing fugitives—about 400 persons—to escape. The East Germany authorities eventually used seismographic and acoustic equipment to detect the practice. In 1962, they planned an attempt to use explosives to destroy one tunnel, but this was not carried out as it was apparently sabotaged by a member of the Stasi.


title: Berlin Wall

text: An airborne escape was made by Thomas Krüger, who landed a Zlin Z 42M light aircraft of the "Gesellschaft für Sport und Technik", an East German youth military training organization, at RAF Gatow. His aircraft, registration DDR-WOH, was dismantled and returned to the East Germans by road, complete with humorous slogans painted on it by airmen of the Royal Air Force, such as "Wish you were here" and "Come back soon".


title: Berlin Wall

text: If an escapee was wounded in a crossing attempt and lay on the death strip, no matter how close they were to the Western wall, Westerners could not intervene for fear of triggering engaging fire from the 'Grepos', the East Berlin border guards. The guards often let fugitives bleed to death in the middle of this ground, as in the most notorious failed attempt, that of Peter Fechter (aged 18) at a point near Zimmerstrasse in East Berlin. He was shot and bled to death, in full view of the Western media, on 17 August 1962. Fechter's death created negative publicity worldwide that led the leaders of East Berlin to place more restrictions on shooting in public places and provide medical care for possible "would-be escapers". The last person to be shot and killed while trying to cross the border was Chris Gueffroy on 6 February 1989, while the final person to die in an escape attempt was Winfried Freudenberg who was killed when his homemade natural gas-filled balloon crashed on 8 March 1989.

text: The Wall gave rise to a widespread sense of desperation and oppression in East Berlin, as expressed in the private thoughts of one resident, who confided to her diary "Our lives have lost their spirit… we can do nothing to stop them."

text: On 6 June 1987, David Bowie, who earlier for several years lived and recorded in West Berlin, played a concert close to the Wall. This was attended by thousands of Eastern concertgoers across the Wall, followed by violent rioting in East Berlin. According to Tobias Ruther, these protests in East Berlin were the first in the sequence of riots that led to those of November 1989. Although other factors were probably more influential in the fall of the Wall, upon his death in 2016, the German Foreign Office tweeted ""Good-bye, David Bowie. You are now among #Heroes. Thank you for helping to bring down the #wall.""

text: On 19 July 1988, 16 months before the Wall came down, Bruce Springsteen and the E-Street Band, played Rocking the Wall, a live concert in East Berlin, which was attended by 300,000 in person and broadcast on television. Springsteen spoke to the crowd in German, saying: "I'm not here for or against any government. I've come to play rock 'n' roll for you in the hope that one day all the barriers will be torn down". East Germany and its FDJ youth organization were worried they were losing an entire generation. They hoped that by letting Springsteen in, they could improve their sentiment among East Germans. However, this strategy of "one step backwards, two steps forwards" backfired, and the concert only made East Germans hungrier for more of the freedoms that Springsteen epitomized. While John F. Kennedy and Ronald Reagan delivered their famous speeches from the safety of West Berlin, Springsteen's speaking out against the Wall in the middle of East Berlin added to the euphoria.


title: Berlin Wall

text: On 31 December 1989, American TV actor and pop music singer David Hasselhoff was the headlining performer for the Freedom Tour Live concert, which was attended by over 500,000 people on both sides of the Wall. The live concert footage was directed by music video director Thomas Mignone and aired on broadcast television station Zweites Deutsches Fernsehen ZDF throughout Europe. During shooting, film crew personnel pulled people up from both sides to stand and celebrate on top of the wall. Hasselhoff sang his number one hit song "Looking For Freedom" on a platform at the end of a twenty-meter steel crane that swung above and over the Wall adjacent to the Brandenburg Gate. A small museum was created in 2008 to celebrate Hasselhoff in the basement of the Circus Hostel.


title: Berlin Wall

text: On 26 June 1963, 22 months after the erection of the Berlin Wall, U.S. President John F. Kennedy visited West Berlin. Speaking from a platform erected on the steps of Rathaus Schöneberg for an audience of 450,000 and straying from the prepared script, he declared in his "Ich bin ein Berliner" speech the support of the United States for West Germany and the people of West Berlin in particular:


title: Berlin Wall

text: The message was aimed as much at the Soviets as it was at Berliners and was a clear statement of U.S. policy in the wake of the construction of the Berlin Wall. The speech is considered one of Kennedy's best, both a significant moment in the Cold War and a high point of the New Frontier. It was a great morale boost for West Berliners, who lived in an exclave deep inside East Germany and feared a possible East German occupation.


title: Berlin Wall

text: In a speech at the Brandenburg Gate commemorating the 750th anniversary of Berlin on 12 June 1987, U.S. President Ronald Reagan challenged Mikhail Gorbachev, then the General Secretary of the Communist Party of the Soviet Union, to tear down the Wall as a symbol of increasing freedom in the Eastern Bloc:


title: Berlin Wall

text: In January 1989 GDR leader Erich Honecker predicted that the Wall would stand for 50 or 100 more years if the conditions that had caused its construction did not change.


title: Berlin Wall

text: Due to the increasing economic problems in the Eastern Bloc and the failure of the USSR to intervene in relation to the individual communist states, the brackets of the Eastern Bloc slowly began to loosen from the end of the 1980s. One example is the fall of the communist government in neighboring Poland's 1989 Polish legislative election. Also in June 1989, the Hungarian government began dismantling the electrified fence along its border with Austria (with Western TV crews present) although the border was still very closely guarded and escape was almost impossible.


title: Berlin Wall

text: The opening of a border gate between Austria and Hungary at the Pan-European Picnic on 19 August 1989, which was based on an idea by Otto von Habsburg to test the reaction of Mikhail Gorbachev, then triggered a peaceful chain reaction, at the end of which there was no longer the GDR and the Eastern Bloc had disintegrated. Because with the non-reaction of the USSR and the GDR to the mass exodus, the media-informed Eastern Europeans could feel the increasing loss of power of their governments and more and more East Germans were now trying to flee via Hungary. Erich Honecker explained to the Daily Mirror regarding the Paneuropean picnic and thus showed his people his own inaction: "Habsburg distributed leaflets far into Poland, on which the East German holidaymakers were invited to a picnic. When they came to the picnic, they were given gifts, food and Deutsche Mark, and then they were persuaded to come to the West." Then, in September, more than 13,000 East German tourists escaped through Hungary to Austria. This set up a chain of events. The Hungarians prevented many more East Germans from crossing the border and returned them to Budapest. These East Germans flooded the West German embassy and refused to return to East Germany.


title: Berlin Wall

text: The East German government responded by disallowing any further travel to Hungary but allowed those already there to return to East Germany. This triggered similar events in neighboring Czechoslovakia. This time, however, the East German authorities allowed people to leave, provided that they did so by train through East Germany. This was followed by mass demonstrations within East Germany itself. Protest demonstrations spread throughout East Germany in September 1989. Initially, protesters were mostly people wanting to leave to the West, chanting ("We want out!"). Then protestors began to chant ("We are staying here!"). This was the start of what East Germans generally call the "Peaceful Revolution" of late 1989. The protest demonstrations grew considerably by early November. The movement neared its height on 4 November, when half a million people gathered to demand political change, at the Alexanderplatz demonstration, East Berlin's large public square and transportation hub. On 9 October 1989, the police and army units were given permission to use force against those assembled, but this did not deter the church service and march from taking place, which gathered 70,000 people.


title: Berlin Wall

text: The longtime leader of East Germany, Erich Honecker, resigned on 18 October 1989 and was replaced by Egon Krenz that day.


title: Berlin Wall

text: The wave of refugees leaving East Germany for the West kept increasing. By early November refugees were finding their way to Hungary via Czechoslovakia, or via the West German Embassy in Prague. This was tolerated by the new Krenz government, because of long-standing agreements with the communist Czechoslovak government, allowing free travel across their common border. However, this movement of people grew so large it caused difficulties for both countries. To ease the difficulties, the politburo led by Krenz decided on 9 November to allow refugees to exit directly through crossing points between East Germany and West Germany, including between East and West Berlin. Later the same day, the ministerial administration modified the proposal to include private, round-trip, and travel. The new regulations were to take effect the next day.


title: Berlin Wall

text: Günter Schabowski, the party boss in East Berlin and the spokesman for the SED Politburo, had the task of announcing the new regulations. However, he had not been involved in the discussions about the new regulations and had not been fully updated. Shortly before a press conference on 9 November, he was handed a note announcing the changes, but given no further instructions on how to handle the information. These regulations had only been completed a few hours earlier and were to take effect the following day, so as to allow time to inform the border guards. But this starting time delay was not communicated to Schabowski. At the end of the press conference, Schabowski read out loud the note he had been given. A reporter, ANSA's Riccardo Ehrman, asked when the regulations would take effect. After a few seconds' hesitation, Schabowski replied, "As far as I know, it takes effect immediately, without delay". After further questions from journalists, he confirmed that the regulations included the border crossings through the Wall into West Berlin, which he had not mentioned until then. He repeated that it was immediate in an interview with American journalist Tom Brokaw.


title: Berlin Wall

text: Excerpts from Schabowski's press conference were the lead story on West Germany's two main news programs that night—at 7:17 p.m. on ZDF's "heute" and at 8 p.m. on ARD's "Tagesschau". As ARD and ZDF had broadcast to nearly all of East Germany since the late 1950s and had become accepted by the East German authorities, the news was broadcast there as well simultaneously. Later that night, on ARD's "Tagesthemen", anchorman Hanns Joachim Friedrichs proclaimed, "This 9 November is a historic day. The GDR has announced that, starting immediately, its borders are open to everyone. The gates in the Wall stand open wide."


title: Berlin Wall

text: After hearing the broadcast, East Germans began gathering at the Wall, at the six checkpoints between East and West Berlin, demanding that border guards immediately open the gates. The surprised and overwhelmed guards made many hectic telephone calls to their superiors about the problem. At first, they were ordered to find the "more aggressive" people gathered at the gates and stamp their passports with a special stamp that barred them from returning to East Germany—in effect, revoking their citizenship. However, this still left thousands of people demanding to be let through "as Schabowski said we can". It soon became clear that no one among the East German authorities would take personal responsibility for issuing orders to use lethal force, so the vastly outnumbered soldiers had no way to hold back the huge crowd of East German citizens. Finally, at 10:45 p.m. on 9 November, Harald Jäger, the commander of the Bornholmer Straße border crossing yielded, allowing for the guards to open the checkpoints and allowing people through with little or no identity checking. As the "Ossis" swarmed through, they were greeted by "Wessis" waiting with flowers and champagne amid wild rejoicing. Soon afterward, a crowd of West Berliners jumped on top of the Wall, and were soon joined by East German youngsters. The evening of 9 November 1989 is known as the night the Wall came down.


title: Berlin Wall

text: Another border crossing to the south may have been opened earlier. An account by Heinz Schäfer indicates that he also acted independently and ordered the opening of the gate at Waltersdorf-Rudow a couple of hours earlier. This may explain reports of East Berliners appearing in West Berlin earlier than the opening of the Bornholmer Straße border crossing.


title: Berlin Wall

text: Thirty years after the fall of the Berlin Wall, "The Guardian" collected short stories from 9 November 1989 by five German writers who reflect on the day. In this, Kathrin Schmidt remembers comically: 'I downed almost an entire bottle of schnapps'.


title: Berlin Wall

text: Little is left of the Wall at its original site, which was destroyed almost in its entirety. Three long sections are still standing: an piece of the first (westernmost) wall at the Topography of Terror, site of the former Gestapo headquarters, halfway between Checkpoint Charlie and Potsdamer Platz; a longer section of the second (easternmost) wall along the Spree River near the Oberbaumbrücke, nicknamed East Side Gallery; and a third section that is partly reconstructed, in the north at Bernauer Straße, which was turned into a memorial in 1998. Other isolated fragments, lampposts, other elements, and a few watchtowers also remain in various parts of the city.


title: Berlin Wall

text: Nothing still accurately represents the Wall's original appearance better than a very short stretch at Bernauer Straße associated with the Berlin Wall Documentation Center. Other remnants are badly damaged by souvenir seekers. Fragments of the Wall were taken and some were sold around the world. Appearing both with and without certificates of authenticity, these fragments are now a staple on the online auction service eBay as well as German souvenir shops. Today, the eastern side is covered in graffiti that did not exist while the Wall was guarded by the armed soldiers of East Germany. Previously, graffiti appeared only on the western side. Along some tourist areas of the city centre, the city government has marked the location of the former Wall by a row of cobblestones in the street. In most places only the "first" wall is marked, except near Potsdamer Platz where the stretch of both walls is marked, giving visitors an impression of the dimension of the barrier system.


title: Berlin Wall

text: After the fall of the Berlin Wall, there were initiatives that they want to preserve the death strip walkways and redevelop them into a hiking and cycling area, known as . It is part of the initiative by the Berlin Senate since 11 October 2001.


title: Berlin Wall

text: For many years after reunification, people in Germany talked about cultural differences between East and West Germans (colloquially "Ossis" and "Wessis"), sometimes described as "Mauer im Kopf" (The wall in the head). A September 2004 poll found that 25 percent of West Germans and 12 percent of East Germans wished that East and West should be separated again by a "Wall". A poll taken in October 2009 on the occasion of the 20th anniversary of the fall of the Wall indicated, however, that only about a tenth of the population was still unhappy with the unification (8 percent in the East; 12 percent in the West). Although differences are still perceived between East and West, Germans make similar distinctions between North and South.


title: Berlin Wall

text: A 2009 poll conducted by Russia's VTsIOM, found that more than half of all Russians do not know who built the Berlin Wall. Ten percent of people surveyed thought Berlin residents built it themselves. Six percent said Western powers built it and four percent thought it was a "bilateral initiative" of the Soviet Union and the West. Fifty-eight percent said they did not know who built it, with just 24 percent correctly naming the Soviet Union and its then-communist ally East Germany.


title: Berlin Wall

text: Not all segments of the Wall were ground up as the Wall was being torn down. Many segments have been given to various institutions in the world. They can be found, for instance, in presidential and historical museums, lobbies of hotels and corporations, at universities and government buildings, and in public spaces in different countries of the world.


title: Berlin Wall

text: On 13 August 2011, Germany marked the 50th anniversary of East Germany beginning the erection of the Berlin Wall. Chancellor Angela Merkel joined with President Christian Wulff and Berlin Mayor Klaus Wowereit at the Bernauer Straße memorial park to remember lives and liberty. Speeches extolled freedom and a minute of silence at noon honored those who died trying to flee to the West. "It is our shared responsibility to keep the memory alive and to pass it on to the coming generations as a reminder to stand up for freedom and democracy to ensure that such injustice may never happen again." entreated Mayor Wowereit. "It has been shown once again: Freedom is invincible at the end. No wall can permanently withstand the desire for freedom", proclaimed President Wulff.


title: Killers of the Flower Moon (film)

text: Killers of the Flower Moon is an upcoming American Western crime drama film directed by Martin Scorsese and with a screenplay by Eric Roth and Scorsese, based on the best-selling 2017 non-fiction book "Killers of the Flower Moon: The Osage Murders and the Birth of the FBI" by David Grann, which is based on the series of 1920s Oklahoma murders in the Osage Nation committed after oil was discovered on tribal land. Leonardo DiCaprio, who also serves as producer, stars alongside Robert De Niro, Jesse Plemons, Lily Gladstone, and Brendan Fraser. The film marks the sixth collaboration between Scorsese and DiCaprio as well as the 10th collaboration between Scorsese and De Niro.


title: Killers of the Flower Moon (film)

text: The film is produced by Scorsese's Sikelia Productions and DiCaprio's Appian Way Productions and distributed by Paramount Pictures and Apple TV+. The $200 million budget is reportedly the largest amount ever spent on a movie filmed in Oklahoma.


title: Killers of the Flower Moon (film)

text: Members of the Osage tribe in northeastern Oklahoma are murdered under mysterious circumstances in the 1920s, sparking a major FBI investigation directed by a 29-year-old J. Edgar Hoover and former Texas Ranger Tom White, described by Grann as "an old-style lawman."


title: Killers of the Flower Moon (film)

text: On March 10, 2016, Imperative Entertainment won the bidding war to make a film adaptation of David Grann's nonfiction book "Killers of the Flower Moon" and paid $5 million; the studio's Dan Friedkin and Bradley Thomas would produce the film. In April 2017, it was revealed that Martin Scorsese, Leonardo DiCaprio and Robert De Niro were considering involvement in the film, adapted by Eric Roth. In July 2017, production designer Dante Ferretti revealed that filming would begin in early 2018, with Scorsese directing and DiCaprio starring. However, production stalled until October 2018, when it was announced that the film would be Scorsese's next effort after completing "The Irishman" (2019). At that point, filming was due to begin in the summer of 2019.


title: Killers of the Flower Moon (film)

text: In June 2019, it was announced that Paramount Pictures would distribute the film. On July 26, 2019, Scorsese traveled to the Osage Nation in Pawhuska, Oklahoma to meet with Principal Chief Geoffrey Standing Bear to discuss how the Osage Nation could be involved with the film's production. Days later, it was reported that De Niro had joined the cast with filming tentatively set to commence in the summer of 2020.


title: Killers of the Flower Moon (film)

text: In December 2019, Scorsese's cinematographer Rodrigo Prieto confirmed that the film was expected to start principal photography in March 2020, adding that the "look and feel of the film" was still being figured out. At the 26th Screen Actors Guild Awards on January 19, 2020, DiCaprio officially announced that he and De Niro will star in the film. In April 2020, it was announced that the filming of "Killers of the Flower Moon" had been postponed indefinitely in response to the COVID-19 pandemic. Meanwhile, Scorsese had reached out to Netflix and Apple TV+ to finance and distribute the film, as Paramount had concerns about the film's budget reaching $200 million. Paramount was still open to a deal to be involved with the film alongside an additional partner. In May 2020, Apple TV+ was announced to co-finance and co-distribute the film, with Paramount remaining as distributor.


title: Killers of the Flower Moon (film)

text: In February 2021, Lily Gladstone and Jesse Plemons were added to the cast. Though the role of Tom White, the lead FBI agent, was initially written for DiCaprio, DiCaprio pushed to instead portray the nephew of the film's primary antagonist played by De Niro. As a result, it was reported that Jesse Plemons was cast as Tom White to replace DiCaprio, while DiCaprio was cast as Ernest Burkhart. In March, Tantoo Cardinal, Cara Jade Myers, JaNae Collins and Jillian Dion were added to the cast. William Belleau, Louis Cancelmi, Jason Isbell, Sturgill Simpson, Tatanka Means, Michael Abbott Jr., Pat Healy, and Scott Shepherd joined in April.

text: In April 2021, Jack Fisk signed on as production designer for the film, marking the first collaboration between the Oscar nominee and Martin Scorsese. In June, Steve Eastin, Gary Basaraba and Barry Corbin joined the cast. In August 2021, it was announced that Brendan Fraser and John Lithgow had been added to the cast.


title: Killers of the Flower Moon (film)

text: "Killers of the Flower Moon" was expected to begin production in February 2021 in Oklahoma. Principal photography ultimately began on April 19, 2021, with filming taking place in Osage County and Washington County, namely Pawhuska, Fairfax and Bartlesville.


title: Killers of the Flower Moon (film)

text: In a news release before the beginning of filming, Scorsese said: "We are thrilled to finally start production on "Killers of the Flower Moon" in Oklahoma. To be able to tell this story on the land where these events took place is incredibly important and critical to allowing us to portray an accurate depiction of the time and people. We're grateful to Apple, the Oklahoma Film and Music Office and The Osage Nation, especially all our Osage consultants and cultural advisors, as we prepare for this shoot. We're excited to start working with our local cast and crew to bring this story to life on screen and immortalize a time in American history that should not be forgotten."

text: On May 13, De Niro suffered a quadriceps muscle leg injury off-set and returned to New York City for medical attention; production was not delayed, as De Niro's subsequent scenes would be filmed in June 2021. Filming wrapped on October 1, 2021. On March 25, 2022, Osage Nation Principal Chief Geoffrey Standing Bear told the Tulsa Press Club "he was advised "Killers of the Flower Moon" is tentatively slated to film additional scenes of a traditional community dance in mid-May in Osage County."


title: Cannabis (drug)

text: Cannabis, also known as marijuana among other names, is a psychoactive drug from the cannabis plant. Native to Central or South Asia, the cannabis plant has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries. Tetrahydrocannabinol (THC) is the main psychoactive component of cannabis, which is one of the 483 known compounds in the plant, including at least 65 other cannabinoids, such as cannabidiol (CBD). Cannabis can be used by smoking, vaporizing, within food, or as an extract.


title: Cannabis (drug)

text: Cannabis has various mental and physical effects, which include euphoria, altered states of mind and sense of time, difficulty concentrating, impaired short-term memory, impaired body movement (balance and fine psychomotor control), relaxation, and an increase in appetite. Onset of effects is felt within minutes when smoked, but may take up to 90 minutes when eaten. The effects last for two to six hours, depending on the amount used. At high doses, mental effects can include anxiety, delusions (including ideas of reference), hallucinations, panic, paranoia, and psychosis. There is a strong relation between cannabis use and the risk of psychosis, though the direction of causality is debated. Physical effects include increased heart rate, difficulty breathing, nausea, and behavioral problems in children whose mothers used cannabis during pregnancy; short-term side effects may also include dry mouth and red eyes. Long-term adverse effects may include addiction, decreased mental ability in those who started regular use as adolescents, chronic coughing, susceptibility to respiratory infections, and cannabinoid hyperemesis syndrome.


title: Cannabis (drug)

text: Cannabis is mostly used recreationally or as a medicinal drug, although it may also be used for spiritual purposes. In 2013, between 128 and 232 million people used cannabis (2.7% to 4.9% of the global population between the ages of 15 and 65). It is the most commonly used largely-illegal drug in the world, with the highest use among adults in Zambia, the United States, Canada, and Nigeria, .


title: Cannabis (drug)

text: While cannabis plants have been grown since at least the 3rd millennium BCE, evidence suggests that it was being smoked for psychoactive effects at least 2,500 years ago in the Pamir Mountains, Asia. Since the 14th century, cannabis has been subject to legal restrictions. The possession, use, and cultivation of cannabis has been illegal in most countries since the 20th century. In 2013, Uruguay became the first country to legalize recreational use of cannabis. Other countries to do so are Canada, Georgia, Malta, Mexico, South Africa, and Thailand. In the U.S., the recreational use of cannabis is legalized in 21 states, two territories, and the District of Columbia, though the drug remains federally illegal. In Australia, it is legalized only in the Australian Capital Territory.


title: Cannabis (drug)

text: Medical cannabis, or medical marijuana, refers to the use of cannabis to treat disease or improve symptoms; however, there is no single agreed-upon definition (e.g., cannabinoids derived from cannabis and synthetic cannabinoids are also used). The rigorous scientific study of cannabis as a medicine has been hampered by production restrictions and by the fact that it is classified as an illegal drug by many governments. There is limited evidence suggesting cannabis can be used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, or to treat chronic pain and muscle spasms. Its use for other medical applications is insufficient for drawing conclusions about safety or efficacy. There is evidence supporting the use of cannabis or its derivatives in the treatment of chemotherapy-induced nausea and vomiting, neuropathic pain, and multiple sclerosis. Lower levels of evidence support its use for AIDS wasting syndrome, epilepsy, rheumatoid arthritis, and glaucoma.


title: Cannabis (drug)

text: So far, the medical use of cannabis is legal only in a limited number of territories, including Canada, Belgium, Australia, the Netherlands, New Zealand, Spain, and many U.S. states. This usage generally requires a prescription, and distribution is usually done within a framework defined by local laws.


title: Cannabis (drug)

text: According to DEA Chief Administrative Law Judge, Francis Young, "cannabis is one of the safest therapeutically active substances known to man." Being under the effects of cannabis is usually referred to as being "high" or "stoned." Cannabis consumption has both psychoactive and physiological effects. The "stoned" experience can vary widely, based (among other things) on the user's prior experience with cannabis, and the type of cannabis consumed. When smoking cannabis, a euphoriant effect can occur within minutes of smoking. Aside from a subjective change in perception and mood, the most common short-term physical and neurological effects include increased heart rate, increased appetite, impairment of short-term and working memory, and psychomotor coordination.


title: Cannabis (drug)

text: Additional desired effects from consuming cannabis include relaxation, a general alteration of conscious perception, increased awareness of sensation, increased libido and distortions in the perception of time and space. At higher doses, effects can include altered body image, auditory and/or visual illusions, pseudohallucinations and ataxia from selective impairment of polysynaptic reflexes. In some cases, cannabis can lead to dissociative states such as depersonalization and derealization.


title: Cannabis (drug)

text: Cannabis has held sacred status in several religions and has served as an entheogen – a chemical substance used in religious, shamanic, or spiritual contexts – in the Indian subcontinent since the Vedic period. The earliest known reports regarding the sacred status of cannabis in the Indian subcontinent come from the Atharva Veda, estimated to have been composed sometime around 1400 BCE.


title: Cannabis (drug)

text: In modern culture, the spiritual use of cannabis has been spread by the disciples of the Rastafari movement who use cannabis as a sacrament and as an aid to meditation.


title: Cannabis (drug)

text: Cannabis is consumed in many different ways, all of which involve heating to decarboxylate THCA in the plant into THC. Common available forms are:

text: Onset of effects is felt within minutes when smoked, and may take up to 90 minutes when eaten. Depending on the amount used, the effects last for two to six hours.


title: Cannabis (drug)

text: In 2013, between 128 and 232 million people used cannabis (2.7% to 4.9% of the global population between the ages of 15 and 65). Cannabis is by far the most widely used illicit substance, with the highest use among adults () in Zambia, the United States, Canada, and Nigeria.


title: Cannabis (drug)

text: Between 1973 and 1978, eleven states decriminalized marijuana. In 2001, Nevada reduced marijuana possession to a misdemeanor and since 2012, several other states have decriminalized and even legalized marijuana.


title: Cannabis (drug)

text: In 2018, almost half of the people in the United States had tried marijuana, 16% had used it in the past year, and 11% had used it in the past month. In 2014, daily marijuana use amongst US college students had reached its highest level since records began in 1980, rising from 3.5% in 2007 to 5.9% in 2014 and had surpassed daily cigarette use.


title: Cannabis (drug)

text: In the US, men are over twice as likely to use marijuana as women, and 1829-year-olds are six times more likely to use as over-65-year-olds. In 2015, a record 44% of the US population has tried marijuana in their lifetime, an increase from 38% in 2013 and 33% in 1985.


title: Cannabis (drug)

text: Marijuana use in the United States is three times above the global average, but in line with other Western democracies. Forty-four percent of American 12th graders have tried the drug at least once, and the typical age of first-use is 16, similar to the typical age of first-use for alcohol but lower than the first-use age for other illicit drugs.


title: Cannabis (drug)

text: Acute negative effects may include anxiety and panic, impaired attention and memory, an increased risk of psychotic symptoms, the inability to think clearly, and an increased risk of accidents. Cannabis impairs a person's driving ability, and THC was the illicit drug most frequently found in the blood of drivers who have been involved in vehicle crashes. Those with THC in their system are from three to seven times more likely to be the cause of the accident than those who had not used either cannabis or alcohol, although its role is not necessarily causal because THC stays in the bloodstream for days to weeks after intoxication.


title: Cannabis (drug)

text: Some immediate undesired side effects include a decrease in short-term memory, dry mouth, impaired motor skills, reddening of the eyes, dizziness, feeling tired and vomiting. Some users may experience an episode of acute psychosis, which usually abates after six hours, but in rare instances, heavy users may find the symptoms continuing for many days.


title: Cannabis (drug)

text: Legalization has increased the rates at which children are exposed to cannabis, particularly from edibles. While the toxicity and lethality of THC in children is not known, they are at risk for encephalopathy, hypotension, respiratory depression severe enough to require ventilation, somnolence and coma.


title: Cannabis (drug)

text: Cannabis is suspected of being a potential, and under-reported, contributory factor or direct cause in cases of sudden death, due to the strain it can place on the cardiovascular system. Multiple deaths have been attributed to cannabinoid hyperemesis syndrome.


title: Cannabis (drug)

text: A 16-month survey of Oregon and Alaska emergency departments found a report of the death of an adult who had been admitted for acute cannabis toxicity.


title: Cannabis (drug)

text: A 2015 meta-analysis found that, although a longer period of abstinence was associated with smaller magnitudes of impairment, both retrospective and prospective memory were impaired in cannabis users. The authors concluded that some, but not all, of the deficits associated with cannabis use were reversible. A 2012 meta-analysis found that deficits in most domains of cognition persisted beyond the acute period of intoxication, but was not evident in studies where subjects were abstinent for more than 25 days. Few high quality studies have been performed on the long-term effects of cannabis on cognition, and the results were generally inconsistent. Furthermore, effect sizes of significant findings were generally small. One review concluded that, although most cognitive faculties were unimpaired by cannabis use, residual deficits occurred in executive functions. Impairments in executive functioning are most consistently found in older populations, which may reflect heavier cannabis exposure, or developmental effects associated with adolescent cannabis use. One review found three prospective cohort studies that examined the relationship between self-reported cannabis use and intelligence quotient (IQ). The study following the largest number of heavy cannabis users reported that IQ declined between ages 7–13 and age 38. Poorer school performance and increased incidence of leaving school early were both associated with cannabis use, although a causal relationship was not established. Cannabis users demonstrated increased activity in task-related brain regions, consistent with reduced processing efficiency.


title: Cannabis (drug)

text: A reduced quality of life is associated with heavy cannabis use, although the relationship is inconsistent and weaker than for tobacco and other substances. The direction of cause and effect, however, is unclear.


title: Cannabis (drug)

text: The long-term effects of cannabis are not clear. There are concerns surrounding memory and cognition problems, risk of addiction, and the risk of schizophrenia in young people.


title: Cannabis (drug)

text: Although global abnormalities in white matter and grey matter are not consistently associated with heavy cannabis use, reduced hippocampal volume is consistently found. Amygdala abnormalities are sometimes reported, although findings are inconsistent.


title: Cannabis (drug)

text: Cannabis use is associated with increased recruitment of task-related areas, such as the dorsolateral prefrontal cortex, which is thought to reflect compensatory activity due to reduced processing efficiency. Cannabis use is also associated with downregulation of CB receptors. The magnitude of down regulation is associated with cumulative cannabis exposure, and is reversed after one month of abstinence. There is limited evidence that chronic cannabis use can reduce levels of glutamate metabolites in the human brain.

text: About 9% of those who experiment with marijuana eventually become dependent according to DSM-IV (1994) criteria. A 2013 review estimates daily use is associated with a 10–20% rate of dependence. The highest risk of cannabis dependence is found in those with a history of poor academic achievement, deviant behavior in childhood and adolescence, rebelliousness, poor parental relationships, or a parental history of drug and alcohol problems. Of daily users, about 50% experience withdrawal upon cessation of use (i.e. are dependent), characterized by sleep problems, irritability, dysphoria, and craving. Cannabis withdrawal is less severe than withdrawal from alcohol.

text: According to DSM-V criteria, 9% of those who are exposed to cannabis develop cannabis use disorder, compared to 20% for cocaine, 23% for alcohol and 68% for nicotine. Cannabis use disorder in the DSM-V involves a combination of DSM-IV criteria for cannabis abuse and dependence, plus the addition of craving, without the criterion related to legal troubles.

text: At an epidemiological level, a dose–response relationship exists between cannabis use and increased risk of psychosis and earlier onset of psychosis. Although the epidemiological association is robust, evidence to prove a causal relationship is lacking. But a biological causal pathway is plausible, especially if there is a genetic predisposition to mental illness, in which case cannabis may be a trigger.


title: Cannabis (drug)

text: Cannabis may also increase the risk of depression, but insufficient research has been performed to draw a conclusion. Cannabis use is associated with increased risk of anxiety disorders, although causality has not been established.


title: Cannabis (drug)

text: A review in 2019 found that research was insufficient to determine the safety and efficacy of using cannabis to treat schizophrenia, psychosis, or other mental disorders. Another found that cannabis during adolescence was associated with an increased risk of developing depression and suicidal behavior later in life, while finding no effect on anxiety.


title: Cannabis (drug)

text: Heavy, long-term exposure to marijuana may have physical, mental, behavioral and social health consequences. It may be "associated with diseases of the liver (particularly with co-existing hepatitis C), lungs, heart, and vasculature". A 2014 review found that while cannabis use may be less harmful than alcohol use, the recommendation to substitute it for problematic drinking was premature without further study. Various surveys conducted between 2015 and 2019 found that many users of cannabis substitute it for prescription drugs (including opioids), alcohol, and tobacco; most of those who used it in place of alcohol or tobacco either reduced or stopped their intake of the latter substances.

text: Cannabinoid hyperemesis syndrome (CHS) is a severe condition seen in some chronic cannabis users where they have repeated bouts of uncontrollable vomiting for 24–48 hours.


title: Cannabis (drug)

text: A limited number of studies have examined the effects of cannabis smoking on the respiratory system. Chronic heavy marijuana smoking is associated with respiratory infections, coughing, production of sputum, wheezing, and other symptoms of chronic bronchitis. The available evidence does not support a causal relationship between cannabis use and chronic obstructive pulmonary disease. Short-term use of cannabis is associated with bronchodilation. Other side effects of cannabis use include cannabinoid hyperemesis syndrome (CHS), a condition which involves recurrent nausea, cramping abdominal pain, and vomiting.

text: Cannabis smoke contains thousands of organic and inorganic chemical compounds. This tar is chemically similar to that found in tobacco smoke, and over fifty known carcinogens have been identified in cannabis smoke, including; nitrosamines, reactive aldehydes, and polycylic hydrocarbons, including benz[a]pyrene. Cannabis smoke is also inhaled more deeply than tobacco smoke. , there is no consensus regarding whether cannabis smoking is associated with an increased risk of cancer. Light and moderate use of cannabis is not believed to increase risk of lung or upper airway cancer. Evidence for causing these cancers is mixed concerning heavy, long-term use. In general there are far lower risks of pulmonary complications for regular cannabis smokers when compared with those of tobacco. A 2015 review found an association between cannabis use and the development of testicular germ cell tumors (TGCTs), particularly non-seminoma TGCTs. Another 2015 meta-analysis found no association between lifetime cannabis use and risk of head or neck cancer. Combustion products are not present when using a vaporizer, consuming THC in pill form, or consuming cannabis foods.

text: There is concern that cannabis may contribute to cardiovascular disease, but , evidence of this relationship was unclear. Research in these events is complicated because cannabis is often used in conjunction with tobacco, and drugs such as alcohol and cocaine that are known to have cardiovascular risk factors. Smoking cannabis has also been shown to increase the risk of myocardial infarction by 4.8 times for the 60 minutes after consumption.


title: Cannabis (drug)

text: There is preliminary evidence that cannabis interferes with the anticoagulant properties of prescription drugs used for treating blood clots. , the mechanisms for the anti-inflammatory and possible pain relieving effects of cannabis were not defined, and there were no governmental regulatory approvals or clinical practices for use of cannabis as a drug.

text: Emergency room (ER) admissions associated with cannabis use rose significantly from 2012 to 2016; adolescents from age 12–17 had the highest risk. At one Colorado medical center following legalization, approximately two percent of ER admissions were classified as cannabis users. The symptoms of one quarter of these users were partially attributed to cannabis (a total of 2567 out of 449,031 patients); other drugs were sometimes involved. Of these cannabis admissions, one quarter were for acute psychiatric effects, primarily suicidal ideation, depression, and anxiety. An additional third of the cases were for gastrointestinal issues including Cannabinoid hyperemesis syndrome.


title: Cannabis (drug)

text: According to the United States Department of Health and Human Services, there were 455,000 emergency room visits associated with cannabis use in 2011. These statistics include visits in which the patient was treated for a condition induced by or related to recent cannabis use. The drug use must be "implicated" in the emergency department visit, but does not need to be the direct cause of the visit. Most of the illicit drug emergency room visits involved multiple drugs. In 129,000 cases, cannabis was the only implicated drug.

text: There is sufficient evidence of reproductive health harms from cannabis that its use when trying to conceive, during pregnancy, and while breastfeeding, is not advisable.


title: Cannabis (drug)

text: It has been recommended that cannabis use be stopped before and during pregnancy as it can result in negative outcomes for both the mother and baby, such as behavioral problems. However, maternal use of marijuana during pregnancy does not appear to be associated with low birth weight or early delivery after controlling for tobacco use and other confounding factors.

text: The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time. Even after a single administration of THC, detectable levels of THC can be found in the body for weeks or longer (depending on the amount administered and the sensitivity of the assessment method). Investigators have suggested that this is an important factor in marijuana's effects, perhaps because cannabinoids may accumulate in the body, particularly in the lipid membranes of neurons.


title: Cannabis (drug)

text: Researchers confirmed that THC exerts its most prominent effects via its actions on two types of cannabinoid receptors, the CB receptor and the CB receptor, both of which are G protein-coupled receptors. The CB receptor is found primarily in the brain as well as in some peripheral tissues, and the CB receptor is found primarily in peripheral tissues, but is also expressed in neuroglial cells. THC appears to alter mood and cognition through its agonist actions on the CB receptors, which inhibit a secondary messenger system (adenylate cyclase) in a dose-dependent manner.


title: Cannabis (drug)

text: Via CB receptor activation, THC indirectly increases dopamine release and produces psychotropic effects. CBD also acts as an allosteric modulator of the μ- and δ-opioid receptors. THC also potentiates the effects of the glycine receptors. It is unknown if or how these actions contribute to the effects of cannabis.


title: Cannabis (drug)

text: The main psychoactive component of cannabis is tetrahydrocannabinol (THC), which is formed via decarboxylation of tetrahydrocannabinolic acid (THCA) from the application of heat. Raw leaf is not psychoactive because the cannabinoids are in the form of carboxylic acids. THC is one of the 483 known compounds in the plant, including at least 65 other cannabinoids, such as cannabidiol (CBD).


title: Cannabis (drug)

text: THC and its major (inactive) metabolite, THC-COOH, can be measured in blood, urine, hair, oral fluid or sweat using chromatographic techniques as part of a drug use testing program or a forensic investigation of a traffic or other criminal offense. The concentrations obtained from such analyses can often be helpful in distinguishing active use from passive exposure, elapsed time since use, and extent or duration of use. These tests cannot, however, distinguish authorized cannabis smoking for medical purposes from unauthorized recreational smoking. Commercial cannabinoid immunoassays, often employed as the initial screening method when testing physiological specimens for marijuana presence, have different degrees of cross-reactivity with THC and its metabolites. Urine contains predominantly THC-COOH, while hair, oral fluid and sweat contain primarily THC. Blood may contain both substances, with the relative amounts dependent on the recency and extent of usage.


title: Cannabis (drug)

text: The Duquenois–Levine test is commonly used as a screening test in the field, but it cannot definitively confirm the presence of cannabis, as a large range of substances have been shown to give false positives. Researchers at John Jay College of Criminal Justice reported that dietary zinc supplements can mask the presence of THC and other drugs in urine. However, a 2013 study conducted by researchers at the University of Utah School of Medicine refute the possibility of self-administered zinc producing false-negative urine drug tests.

text: CBD is a 5-HT receptor agonist, which is under laboratory research to determine if it has an anxiolytic effect. It is often claimed that sativa strains provide a more stimulating psychoactive high while indica strains are more sedating with a body high. However, this is disputed by researchers.


title: Cannabis (drug)

text: A 2015 review found that the use of high CBD-to-THC strains of cannabis showed significantly fewer positive symptoms, such as delusions and hallucinations, better cognitive function and both lower risk for developing psychosis, as well as a later age of onset of the illness, compared to cannabis with low CBD-to-THC ratios.


title: Cannabis (drug)

text: According to the United Nations Office on Drugs and Crime (UNODC), "the amount of THC present in a cannabis sample is generally used as a measure of cannabis potency." The three main forms of cannabis products are the flower/fruit, resin (hashish), and oil (hash oil). The UNODC states that cannabis often contains 5% THC content, resin "can contain up to 20% THC content", and that "Cannabis oil may contain more than 60% THC content."


title: Cannabis (drug)

text: A 2012 review found that the THC content in marijuana had increased worldwide from 1970 to 2009. It is unclear, however, whether the increase in THC content has caused people to consume more THC or if users adjust based on the potency of the cannabis. It is likely that the higher THC content allows people to ingest less tar. At the same time, CBD levels in seized samples have lowered, in part because of the desire to produce higher THC levels and because more illegal growers cultivate indoors using artificial lights. This helps avoid detection but reduces the CBD production of the plant.


title: Cannabis (drug)

text: Australia's National Cannabis Prevention and Information Centre (NCPIC) states that the buds (infructescences) of the female cannabis plant contain the highest concentration of THC, followed by the leaves. The stalks and seeds have "much lower THC levels". The UN states that the leaves can contain ten times less THC than the buds, and the stalks one hundred times less THC.


title: Cannabis (drug)

text: After revisions to cannabis scheduling in the UK, the government moved cannabis back from a class C to a class B drug. A purported reason was the appearance of high potency cannabis. They believe skunk accounts for between 70 and 80% of samples seized by police (despite the fact that skunk can sometimes be incorrectly mistaken for all types of herbal cannabis). Extracts such as hashish and hash oil typically contain more THC than high potency cannabis infructescences.

text: Hemp buds (or low-potency cannabis buds) laced with synthetic cannabinoids started to be sold as cannabis street drug in 2020.


title: Cannabis (drug)

text: The short-term effects of cannabis can be altered if it has been laced with opioid drugs such as heroin or fentanyl. The added drugs are meant to enhance the psychoactive properties, add to its weight, and increase profitability, despite the increased danger of overdose.


title: Cannabis (drug)

text: Marijuana or marihuana (herbal cannabis) consists of the dried flowers and fruits and subtending leaves and stems of the female cannabis plant. This is the most widely consumed form, containing 3% to 20% THC, with reports of up to 33% THC. This is the stock material from which all other preparations are derived. Although herbal cannabis and industrial hemp derive from the same species and contain the psychoactive component (THC), they are distinct strains with unique biochemical compositions and uses. Hemp has lower concentrations of THC and higher concentrations of CBD, which gives lesser psychoactive effects.

text: Kief is a powder, rich in trichomes, which can be sifted from the leaves, flowers and fruits of cannabis plants and either consumed in powder form or compressed to produce cakes of hashish. The word "kif" derives from colloquial Arabic "", meaning "pleasure".


title: Cannabis (drug)

text: Hashish (also spelled hasheesh, hashisha, or simply hash) is a concentrated resin cake or ball produced from pressed kief, the detached trichomes and fine material that falls off cannabis fruits, flowers and leaves. or from scraping the resin from the surface of the plants and rolling it into balls. It varies in color from black to golden brown depending upon purity and variety of cultivar it was obtained from. It can be consumed orally or smoked, and is also vaporized, or 'vaped'. The term "rosin hash" refers to a high quality solventless product obtained through heat and pressure.

text: Cannabinoids can be extracted from cannabis plant matter using high-proof spirits (often grain alcohol) to create a tincture, often referred to as "green dragon". Nabiximols is a branded product name from a tincture manufacturing pharmaceutical company.


title: Cannabis (drug)

text: Hash oil is a resinous matrix of cannabinoids obtained from the cannabis plant by solvent extraction, formed into a hardened or viscous mass. Hash oil can be the most potent of the main cannabis products because of its high level of psychoactive compound per its volume, which can vary depending on the plant's mix of essential oils and psychoactive compounds. Butane and supercritical carbon dioxide hash oil have become popular in recent years.


title: Cannabis (drug)

text: There are many varieties of cannabis infusions owing to the variety of non-volatile solvents used. The plant material is mixed with the solvent and then pressed and filtered to express the oils of the plant into the solvent. Examples of solvents used in this process are cocoa butter, dairy butter, cooking oil, glycerine, and skin moisturizers. Depending on the solvent, these may be used in cannabis foods or applied topically.

text: "Marihuana prensada" ('pressed marijuana') is a cannabis-derived product widespread among the lower classes of South America, especially from the 90s. Locally it is known as "paraguayo" or "paragua", since its main producer is Paraguay. Marijuana is dried and mixed with binding agents that make it toxic and highly harmful to health. It is cut into the shape of bricks ("ladrillos") and sold for a low price in Argentina, Brazil, Chile, Peru, Venezuela, and even the United States.

text: Cannabis is indigenous to Central or South Asia and its uses for fabric and rope dates back to the Neolithic age in China and Japan. It is unclear when cannabis first became known for its psychoactive properties. The oldest archeological evidence for the burning of cannabis was found in Romanian kurgans dated 3,500 BC, and scholars suggest that the drug was first used in ritual ceremonies by Proto-Indo-European tribes living in the Pontic-Caspian steppe during the Chalcolithic period, a custom they eventually spread throughout Western Eurasia during the Indo-European migrations. Some research suggests that the ancient Indo-Iranian drug soma, mentioned in the Vedas, sometimes contained cannabis. This is based on the discovery of a basin containing cannabis in a shrine of the second millennium BC in Turkmenistan.

text: Cannabis was known to the ancient Assyrians, who discovered its psychoactive properties through the Iranians. Using it in some religious ceremonies, they called it "qunubu" (meaning "way to produce smoke"), a probable origin of the modern word "cannabis". The Iranians also introduced cannabis to the Scythians, Thracians and Dacians, whose shamans (the "kapnobatai""those who walk on smoke/clouds") burned cannabis infructescences to induce trance. The plant was used in China before 2800 BC, and found therapeutic use in India by 1000 BC, where it was used in food and drink, including "bhang".

text: Cannabis has an ancient history of ritual use and has been used by religions around the world. It has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries. The earliest evidence of cannabis smoking has been found in the 2,500-year-old tombs of Jirzankal Cemetery in the Pamir Mountains in Western China, where cannabis residue were found in burners with charred pebbles possibly used during funeral rituals. Hemp seeds discovered by archaeologists at Pazyryk suggest early ceremonial practices like eating by the Scythians occurred during the 5th to 2nd century BC, confirming previous historical reports by Herodotus. It was used by Muslims in various Sufi orders as early as the Mamluk period, for example by the Qalandars. Smoking pipes uncovered in Ethiopia and carbon-dated to around AD 1320 were found to have traces of cannabis.

text: Cannabis was introduced to the New World by the Spaniards in 1530–1545. Following an 1836–1840 travel in North Africa and the Middle East, French physician Jacques-Joseph Moreau wrote on the psychological effects of cannabis use; he founded the Paris' Club des Hashischins in 1844. In 1842, Irish physician William Brooke O'Shaughnessy, who had studied the drug while working as a medical officer in Bengal with the East India Company, brought a quantity of cannabis with him on his return to Britain, provoking renewed interest in the West. Examples of classic literature of the period featuring cannabis include "Les paradis artificiels" (1860) by Charles Baudelaire and "The Hasheesh Eater" (1857) by Fitz Hugh Ludlow.

text: Cannabis was criminalized in some countries beginning in the 14th century and was illegal in most countries by the middle of the 20th century. The colonial government of Mauritius banned cannabis in 1840 over concerns on its effect on Indian indentured workers; the same occurred in Singapore in 1870. In the United States, the first restrictions on sale of cannabis came in 1906 (in the District of Columbia). Canada criminalized cannabis in "The Opium and Narcotic Drug Act, 1923", before any reports of the use of the drug in Canada, but eventually legalized its consumption for recreational and medicinal purposes in 2018.


title: Cannabis (drug)

text: In 1925, a compromise was made at an international conference in The Hague about the International Opium Convention that banned exportation of "Indian hemp" to countries that had prohibited its use, and requiring importing countries to issue certificates approving the importation and stating that the shipment was required "exclusively for medical or scientific purposes". It also required parties to "exercise an effective control of such a nature as to prevent the illicit international traffic in Indian hemp and especially in the resin". In the United States in 1937, the Marihuana Tax Act was passed, and prohibited the production of hemp in addition to cannabis.

text: In 1972, the Dutch government divided drugs into more- and less-dangerous categories, with cannabis being in the lesser category. Accordingly, possession of or less was made a misdemeanor. Cannabis has been available for recreational use in coffee shops since 1976. Cannabis products are only sold openly in certain local "coffeeshops" and possession of up to for personal use is decriminalized, however: the police may still confiscate it, which often happens in car checks near the border. Other types of sales and transportation are not permitted, although the general approach toward cannabis was lenient even before official decriminalization.

text: In Uruguay, President Jose Mujica signed legislation to legalize recreational cannabis in December 2013, making Uruguay the first country in the modern era to legalize cannabis. In August 2014, Uruguay legalized growing up to six plants at home, as well as the formation of growing clubs (Cannabis social club), and a state-controlled marijuana dispensary regime.

text: The United Nations' "World Drug Report" stated that cannabis "was the world's most widely produced, trafficked, and consumed drug in the world in 2010", and estimated between 128 million and 238 million users globally in 2015.


title: Cannabis (drug)

text: Cannabis has been one of the most used psychoactive drugs in the world since the late 20th century, following only tobacco and alcohol in popularity. According to Vera Rubin, the use of cannabis has been encompassed by two major cultural complexes over time: a continuous, traditional folk stream, and a more circumscribed, contemporary configuration. The former involves both sacred and secular use, and is usually based on small-scale cultivation: the use of the plant for cordage, clothing, medicine, food, and a "general use as an euphoriant and symbol of fellowship." The second stream of expansion of cannabis use encompasses "the use of hemp for commercial manufacturers utilizing large-scale cultivation primarily as a fiber for mercantile purposes"; but it is also linked to the search for psychedelic experiences (which can be traced back to the formation of the Parisian Club des Hashischins).


title: Cannabis (drug)

text: Since the beginning of the 20th century, most countries have enacted laws against the cultivation, possession or transfer of cannabis. These laws have had an adverse effect on cannabis cultivation for non-recreational purposes, but there are many regions where handling of cannabis is legal or licensed. Many jurisdictions have lessened the penalties for possession of small quantities of cannabis so that it is punished by confiscation and sometimes a fine, rather than imprisonment, focusing more on those who traffic the drug on the black market.


title: Cannabis (drug)

text: In some areas where cannabis use had been historically tolerated, new restrictions were instituted, such as the closing of cannabis coffee shops near the borders of the Netherlands, and closing of coffee shops near secondary schools in the Netherlands. In Copenhagen, Denmark in 2014, mayor Frank Jensen discussed possibilities for the city to legalize cannabis production and commerce.


title: Cannabis (drug)

text: Some jurisdictions use free voluntary treatment programs and/or mandatory treatment programs for frequent known users. Simple possession can carry long prison terms in some countries, particularly in East Asia, where the sale of cannabis may lead to a sentence of life in prison or even execution. Political parties, non-profit organizations, and causes based on the legalization of medical cannabis and/or legalizing the plant entirely (with some restrictions) have emerged in such countries as China and Thailand.
