A new study published in January’s edition of the journal Addictive Behaviors has concluded that cannabis use does not increase the odds of aggression between intimate partners, whereas alcohol directly increases the possibility of such aggression.
For the study, male college students in relationships committed daily surveys for a 90-day period, assessing their cannabis and alcohol use, as well as any act of aggression they committed towards their partner, whether it be physical aggression (any forceful act with the intent of causing injury), psychological aggression (insults, belittling, threats or intimidation) and sexual aggression (forced sexual contact or coercion).
The results determined that on days where participants used alcohol, there was a substantial increase in the likelihood of that person committing an act of physical or sexual aggression, and the likelihood increased as the number of drinks increased. The odds of psychological aggression increased on days where participants drank heavily (5 or more drinks).
However, researchers found that cannabis use, regardless of how much or how often, did not increase the likelihood of aggression.
Researchers concluded that “Marijuana use days did not increase the odds of any type of aggression.”
