Study finds cannabis use linked to higher risk of violence and victimization
A meta-analysis published in Psychological Medicine by King's College London researchers found that cannabis users showed a statistically higher likelihood of committing violent acts. The same analysis found cannabis use, especially among women and mixed-gender groups, was significantly associated with a greater risk of being a victim of violence.

The researchers stress this is a correlation, not proof that cannabis causes violence, since other social and psychological factors likely play a role. Coauthor Marta Di Forti suggests the findings allow clinicians to discuss risks more confidently without stigmatizing cannabis users broadly, while Sir Robin Murray argues the debate over cannabis legalization should expand beyond effects on individual users to include wider public safety concerns.
- Meta-analysis in Psychological Medicine links cannabis use to increased risk of committing and experiencing violence.
- Women and mixed-gender groups showed a stronger association with victimization risk.
- Researchers caution the link is correlational, not causal, and call for more nuanced societal and clinical responses.
