Global Review Reveals Nuanced Effects of Cannabis Legalization

A comprehensive systematic review published in Milbank Quarterly analyzed 176 studies examining the effects of cannabis policy changes worldwide, revealing complex and often contradictory outcomes that warrant careful interpretation. The research synthesis highlights that legalization impacts vary significantly across jurisdictions, affecting public health, criminal justice, and medical access differently than initially predicted. The findings suggest policymakers and healthcare providers should approach cannabis legalization with nuance, considering both potential therapeutic benefits for conditions like chronic pain and anxiety alongside documented risks. This evidence-based review underscores the importance of evidence-based regulation that balances medical access with public health safeguards. The study calls for continued research and monitoring of legalization's long-term consequences across different populations.
