Meta-Analysis Identifies Correlation Between Cannabis Use and Increased Violence Risk

A systematic review of 63 studies involving 265,000 individuals indicates a significant association between cannabis use and an increased likelihood of both committing and experiencing violence. Data suggests that cannabis users in the general population are twice as likely to commit violent acts, while those in psychiatric care exhibit a two-and-a-half-fold increase in risk compared to non-users.

Criminal conviction rates for violent offenses are estimated to be three to four times higher among cannabis users. The study also identifies a correlation between cannabis use and a 50% increase in the likelihood of becoming a victim of violence, with higher prevalence observed among women.

Researchers emphasize that these findings demonstrate an association rather than direct causation, as variables such as alcohol consumption and socioeconomic factors remain significant contributors. The study recommends that mental health services integrate cannabis screening into violence risk assessments and that public health policy incorporate these findings into broader risk communication strategies.
