By The Herb House Desk·June 17, 2026
A recent international review indicates that while decriminalization or strict regulation of cannabis access does not appear to increase usage, commercial sales are associated with a rise in both the number of users and instances of mental health problems such as psychosis.
The analysis focused on changes in policy between 2000 and 2025, examining the impact of new regulations on the number of individuals using cannabis, its potency, and the prevalence of psychosis.
