Canada’s organized crime groups and gangs are much less likely to produce and traffic marijuana than they are other illicit drugs such as cocaine and crystal methamphetamine, according to a new federal study that tracked drug violations from police forces in four cities across three provinces. The new report from Statistics Canada analyzed all drug-related violations over a two-year period in Victoria, Vancouver, Regina and Waterloo, Ont., and found that police linked organized crime to 39 per cent of all cannabis-trafficking charges and 6 per cent of cases involving the production of marijuana.
