Legalization of cannabis in Canada has potential benefits — lower criminal justice costs, new government and private revenue sources — but we must also recognize the public health costs of cannabis use. It’s vital to ensure that governments at all levels use the available policy levers to reduce these costs. According to the Canadian Substance Use Costs and Harms study, cannabis accounted for 7 percent of the cost of substance use in Canada in 2014: $2.8 billion out of $38.4 billion. This figure includes costs associated with health care for those with health conditions related to cannabis use (such as cannabis dependence, injury from driving accidents due to cannabis impairment and lung cancer) as well as lost productivity due to these health conditions.
