Canada: The government intends to legalize cannabis in 2017

Canada's Liberal government will introduce a law in spring 2017 to legalize recreational cannabis, it said on 20 April, fulfilling an election pledge. Canadian Prime Minister Justin Trudeau promised during last year's election campaign that his Liberals would legalize recreational cannabis, but the time frame has been unclear. Trudeau has previously admitted to smoking cannabis a few times in his life but said he never enjoyed it much.

Health Minister Jane Philpott, speaking at a special session of the United Nations General Assembly in New York, said the Canadian law will ensure cannabis is kept away from children and keep criminals from profiting from its sale. "We will work with law enforcement partners to encourage appropriate and proportionate criminal justice measures," she said. Gerard Deltell from Canada's opposition Conservatives, said the country's proposed legislation would harm people's health and lead to life-long problems among users. The Canadian government has not provided details on production and distribution plans.

Science/Human: Long-term cannabis use was associated with a small increase of mortality
In a study with 50,373 Swedish male military conscripts (ages 18-19), who were followed in the National Cause of Death Register up to around age 60, heavy cannabis use at the start of the study was associated with a higher risk of death (hazard ratio=1.4) than those without such a history. Authors noted that the results “should be interpreted with caution because of a lack of information on confounders in the period after conscription.” Thus, it is unclear if cannabis is the cause for this higher risk.
