Objective
We sought to examine changes in health service use and incident cases of psychotic disorder following cannabis legalization, during a period of tight restrictions on retail stores and product types.
Findings/Key points
We did not find evidence of increases in health service use or incident cases of psychotic disorders over the short-term (17 month) period following cannabis legalization. However, we found clear increasing trends in health service use and incident cases of substance-induced psychotic disorders over the entire observation window (2014–2020).
Design/methods
Cross-sectional interrupted time-series analysis using linked population-based health administrative data from Ontario from January 2014 to March 2020.
