What is Marijuana? 

Marijuana (THC) is considered to be a major drug of abuse.  After smoking or oral administration, the major psychoactive compound, tetrahydrocannabinol, is extensively metabolized before excretion. The excretion half-life of cannabinoid metabolites in urine, estimated by different techniques, ranges from one to ten days. Google © Copyright Expomed 1995-2019

Marijuana Abuse

Marijuana is usually smoked as a cigarette (called a joint) or in a pipe or bong. It is also smoked in blunts, which are cigars that have been emptied of tobacco and refilled with marijuana, sometimes in combination with another drug. Marijuana is also mixed with foods or brewed as a tea.

Physical Effects of Marijuana

When marijuana is smoked, the THC passes from the lungs and into the  bloodstream, which carries the chemical to the organs throughout the body, including the brain. In the brain, the THC connects to specific sites called cannabinoid receptors on nerve cells and influences the activity of those cells. The effect of marijuana on perception and coordination are responsible for serious impairments in learning, associative processes, and psychomotor behavior (driving abilities). Long term, regular use can lead to physical dependence and withdrawal following discontinuation, as well as psychic addiction or dependence.

What Does Marijuana Look Like?
