This joint resolution from the Montana Legislature calls for an interim study to assess the public health and safety impacts of marijuana legalization in the state. The study aims to address various concerns, including trends in emergency room visits related to marijuana use, the effects of youth marijuana consumption on academic performance, and the implications for the criminal justice system. It will also evaluate the demand for substance use disorder treatment services and the prevalence of marijuana-related mental health disorders. The resolution emphasizes the need for a centralized data system to better inform policymakers and communities about the effects of marijuana legalization.

The study will engage a wide range of stakeholders, including educators, health professionals, law enforcement, and community leaders, to ensure a comprehensive and collaborative approach. Upon completion, the findings will be compiled into a report that outlines data summaries, identifies gaps in policy and data collection, and provides recommendations for improving marijuana policy in Montana. The final results of the study are required to be reported to the 70th Legislature by September 15, 2026.
