Levels of support and consumer perceptions of cannabis regulations in Canada.
Background: Canada legalized cannabis for adult (recreational) use in 2018, alongside regulations on the sale, use, and possession of cannabis. To date, there is little evidence on consumer perceptions and support of cannabis regulations.Objectives: This study examined perceptions of nine cannabis regulatory policies, including differences by cannabis consumption and provincial policy.Methods: National survey data were analyzed from Wave 5 of the International Cannabis Policy Study conducted online in 2022 with 16,812 Canadians aged 16+ years, 62% of which were assigned female-at-birth. Weighted logistic regression models examined support for nine policy variables.Results: Support among Canadians was greatest for health warnings on cannabis products (62.6%), legalization for adult use (58.5%), and retail store window-coverings (49.2%), followed by a vaping/extract THC limit (40.1%), retail store density (35.5%), government-only store models (34.6%), the THC limit on edibles (32.3%), and advertising restrictions (31.8%). The 30 g purchasing limit had the least consumer support (10.1%). As consumption increased, opposition generally increased, although support remained high among consumers. Compared to non-consumers, daily consumers were more likely to oppose window-coverings (OR = 1.43, CI95 = 1.16-1.75, p = .001). Where policies differed provincially, few differences in support were observed. No differences in support for THC limits on vaping/extracts were observed between Newfoundland, Nova Scotia, and Quebec versus the rest of Canada, despite stronger vaping/extract regulations (OR = 1.05, CI95 = 0.87-1.28, p = .597).Conclusion: Canadians generally support existing cannabis regulations that were implemented to support public health. The high level of support among consumers suggests that the comprehensive regulations may not undermine transitions to legal retail sources.

The American Journal of Drug and Alcohol Abuse (AJDAA) is an international journal published six times per year and provides an important and stimulating venue for the exchange of ideas between the researchers working in diverse areas, including public policy, epidemiology, neurobiology, and the treatment of addictive disorders. AJDAA includes a wide range of translational research, covering preclinical and clinical aspects of the field. AJDAA covers these topics with focused data presentations and authoritative reviews of timely developments in our field. Manuscripts exploring addictions other than substance use disorders are encouraged. Reviews and Perspectives of emerging fields are given priority consideration.
Areas of particular interest include: public health policy; novel research methodologies; human and animal pharmacology; human translational studies, including neuroimaging; pharmacological and behavioral treatments; new modalities of care; molecular and family genetic studies; medicinal use of substances traditionally considered substances of abuse.
