Highlights from a 2009 Statistics Canada Juristat article:

• For 30 years, drug offence rates in British Columbia have consistently been among the highest in Canada. In 2007, the rate in British Columbia was double the rate in Saskatchewan, the next highest province.
• In 2006, most cannabis production seizures by the Royal Canadian Mounted Police (RCMP) in western Canada, particularly in British Columbia, were from indoor facilities, whereas those in eastern Canada were mainly from outdoor facilities.
• "Super labs", used for the mass production of certain synthetic drugs such as methamphetamine, have been located by police in British Columbia, Ontario and Quebec, the same provinces to report the highest rates of illegal production of "other" drugs.
• In recent years, the highest rates of drug offences among census metropolitan areas have been reported in Vancouver, Trois-Rivières, Victoria, Abbotsford and Gatineau. The rates in Vancouver and Victoria have been among the highest for more than fifteen years.
• Among all youth accused of a drug-related offence in 2007, those in British Columbia, Newfoundland and Labrador and the three territories were most likely to be cleared by other means.
