Illegal drug trade in Colombia
The illegal drug trade in Colombia has, since the 1970s, centered successively on four major drug trafficking cartels: Medellín, Cali, Norte del Valle, and North Coast, as well as several bandas criminales, or BACRIMs. The trade eventually created a new social class and influenced several aspects of Colombian culture, economics, and politics.
