The increase in illicit demand for cocaine is related to the social acceptability of cocaine use. Cocaine abuse has spread from affluent adults to middle income groups and young people. Because of increased demand, there has been a great increase in illicit supply by large and sophisticated trafficking organizations. More than half of Canada's illicit cocaine was illegally produced in Colombia with raw materials obtained from Bolivia and Peru. Cocaine is smuggled into Canada by commercial air transport, arriving at three principal ports of entry: Vancouver, Toronto, and Montreal. Canadian law enforcement efforts cause traffickers to move their operations to other areas to avoid detection. Experts expect Canadian use of cocaine to increase. (Author abstract modified.)
