Maastricht, Netherlands: Cannabis exposure diminishes feelings of aggression while alcohol exposure facilitates aggressive behavior, according to clinical data published in the journal Psychopharmacology.

Investigators from Maastricht University in the Netherlands and Frankfurt University in Germany evaluated subjects’ self-reported response to aggressive stimuli following exposure to alcohol, cannabis or placebo. Participants’ responses were measured using a visual analog scale.

Researchers reported that alcohol and cannabis intoxication resulted in disparate responses among participants.

They concluded, “The results in the present study support the hypothesis that acute alcohol intoxication increases feelings of aggression and that acute cannabis intoxication reduces feelings of aggression following aggression exposure.”

The finding is consistent with that of prior studies reporting that cannabis exposure is associated with a decreased likelihood of violent behavior.
