STUDY FINDS POT - UNLIKE ALCOHOL AND COCAINE - NOT ASSOCIATED WITH VIOLENCE

NORML - Cannabis use is not independently associated with causing violence, according to the results of a multivariate analysis to be published in the journal Addictive Behaviors. Investigators at the University of Victoria, Centre for Addictions Research assessed how frequently subjects in a substance abuse treatment facility reported using cocaine, alcohol, and/or cannabis in the hours immediately prior to committing a violent act. Researchers also evaluated subjects' personality for characteristics associated with violent behavior.

Investigators concluded: "When analyses were conducted controlling for covariates, the frequency of alcohol and cocaine use was significantly related to violence, suggesting that pharmacological effects [of the drugs] may play a role in violence. Frequency of cannabis use, however, was not significantly related to violence when controlling for other factors."

The study's conclusions are similar to the findings of a pair of recent government reports refuting allegations that cannabis use triggers violent behavior. The first, published by the Canadian Senate in 2002, determined: "Cannabis use does not induce users to commit other forms of crime. Cannabis use does not increase aggressiveness or anti-social behavior."
