About The Study: In this study, individuals with psychosis reported a large increase in current cannabis use following legalization and commercialization of cannabis in their state, and by larger amounts than previously reported estimates of the general population. Given how cannabis can negatively affect illness course and health service utilization in individuals with psychosis, these results should be considered by regulators designing policies around taxation, potency, advertising, and health warnings.
