Neil Boyd, a criminology professor at Simon Fraser University, concludes in a new study financed by Sensible BC that the annual police- and court-related costs of enforcing marijuana possession in . alone is “reasonably and conservatively” estimated at $ million per year. has the highest police-reported rate of cannabis offences of any province, and rising: 19,400 in 2011. Of those, almost 16,600 were for possession, leading to almost 3,800 charges, double the number in 2005. As arrests increase, Boyd estimates costs will hit $ million within five years. Added to that will be the cost of jailing people under new mandatory minimum sentences included in the Safe Streets and Communities Act.
