Cannabis use by workers before and after legalization in Canada
On October 17, 2018, the non-medical use of cannabis was legalized in Canada.

The studies explored changes in cannabis consumption habits among workers; changes in their perceptions about such consumption; associations between cannabis consumption and occupational injury risks; as well as the use of cannabis to treat symptoms in the aftermath of a work-related injury/illness. This Issue Briefing provides an overview of findings from these two studies and the potential implications of this research for employers and policy-makers.
