Cannabis Users Were Twice as Likely to Commit Violence, Review Finds
The review found about twice the odds of violence among cannabis users, while longitudinal studies showed a smaller association.
- A large review published in Psychological Medicine by researchers at the Institute of Psychiatry, Psychology & Neuroscience at King College London found cannabis users are more likely to commit violent acts and experience victimization.
- Researchers combined data from 63 studies involving more than 265,000 people to examine the link, analyzing the general population separately from those in psychiatric care.
- Professor Sir Robin Murray of the IoPPN said cannabis users in the general population were "around twice as likely to have committed a violent act" as non-users; psychiatric patients who used cannabis showed higher risks.
- Researchers argue Mental Health services should routinely evaluate Cannabis Use when assessing violence risks, though the review identifies an association and does not prove cannabis directly causes violence.
- Studies following people over time found a smaller association , suggesting unmeasured factors like neighborhood or peer groups may explain findings; most research predated high-potency cannabis becoming common.

A review of more than 265,000 people found that cannabis use was associated with higher rates of both committing violence and becoming a victim of it. The researchers say the link is significant but does not prove cannabis itself is the cause.
Cannabis use linked to higher risk of violence, major review finds
People who use cannabis are more likely both to carry out violent acts and to experience violence, according to one of the most comprehensive reviews of the evidence to date, led by researchers at King's College London.
Researchers have reviewed 63 studies involving more than 265,000 people and now conclude that people who smoke marijuana are more likely than others to exhibit a certain type of behavior.
This relationship is not cause and effect, and it is possible that both marijuana use and violence are caused by another individual or social factor. The post Researchers: Marijuana use can double the likelihood of committing violence appeared first on Digiato.
