Crime: This Bud's For The U.S.

Currently, a grower in Canada who has been convicted can expect less than two years of house arrest and a trafficker anywhere from three months to five years, served either at home or in prison, compared with the minimum punishment of five to 10 years that most convicted traffickers and growers receive in U.S. federal court. But as the violence has increased and cultivation of the crop has moved into residential areas, Canada has begun cracking down on its estimated 50,000 commercial pot growers. Over the past four years, police in Vancouver have seized $288 million worth of marijuana and $8.7 million worth of growing equipment. In Barrie, Ont., in January, police confiscated 30,000 marijuana plants, worth $23 million, inside a former Molson brewery.

One hot, muggy morning in July, a TIME reporter accompanied the Vancouver police as an officer thumped on the door of a two-story brick-and-panel house on a leafy street of manicured lawns. Inside, officers discovered a basement filled wall to wall with more than 300 glossy female cannabis bushes. That bust is pretty routine, but the BC Bud keeps flowing. In the past four years, Vancouver police have made more than 1,500 others, or about one a day.
