 Other criminal groups started smuggling marijuana and cocaine in cities including New York City, Baltimore, Washington, D.C. as well as in New Jersey, California, Florida and Toronto, Ontario, Canada.Other groups such as the Black Mafia in Philadelphia, whose members were also linked to the Nation of Islam, took over the heroin trade and extorted other groups.Later, a younger group paying homage to the Black Mafia named themselves the Junior Black Mafia and were also heavily involved in drug trafficking, specifically crack-cocaine, during the mid-1980s to early 1990s.
