National discussions on cannabis legalization impacted youth cannabis use | Corporate Research Partnerships

National discussions on cannabis legalization, along with increased access to medical marijuana, may have encouraged more high school students to consume the drug years before it became legal in Canada.

A recent study using data from more than 230,000 questionnaires by Canadian high school students in grades 9 to 12 found that almost 10 per cent reported having used the drug at least once per week in 2017-18, with a further 18 per cent saying they had used it at least once in the last year.
