In this presentation, Dr. Nancy Carnide will provide a general overview of what we know (and don’t know) about cannabis use in working populations and describe recent findings of a survey study aimed at understanding changes in patterns of workplace cannabis use and the social norms and perceptions about such use among Canadian workers from pre- to post-legalization.

Take-home messages:

  • Cannabis use before and at work was already occurring in Canadian workplaces even before legalization
  • Nature of use among workers is complex, with workers citing many non-medical and medical reasons for use
  • There are important knowledge gaps that can be addressed by providing evidence-based information to workers

Learning Outcomes

Why workers are an important group to consider when thinking about the implications of cannabis legalization
How Canadian workers were using cannabis and thinking about cannabis use in relation to work before legalization
What has and has not changed since legalization
What gaps exist in Canadian workers’ knowledge about cannabis and its legalization
