Cannabis Use Reduces Risk of Domestic Violence in Married Couples, Finds Study

A new study published by the National Institute of Health has found that cannabis use reduces the risk of domestic violence in both men and women, with the smoking a jointrisk being lowest when both partners are consumers of the plant.

“Research on the association between marijuana use and intimate partner violence (IPV) has generated inconsistent findings, and has been primarily based on cross-sectional data”, claims researchers. “We examined whether husbands’ and wives’ marijuana use predicted both husbands’ and wives’ IPV perpetration over the first 9 years of marriage.”

Using 634 couples, researchers “examined moderation by antisocial behavior, the spouse’s marijuana use, and whether IPV was reported during the year before marriage. These predictive associations were calculated using a time-lagged multivariate generalized multilevel model, simultaneously estimating predictors of husband and wife IPV.” IPV was defined as an act of physical aggression such as slapping, hitting and choking.

According to researchers; “In fully adjusted models, we found that more frequent marijuana use by husbands and wives predicted less frequent IPV perpetration by husbands. Husbands’ marijuana use also predicted less frequent IPV perpetration by wives.”

They continue; “Moderation analyses demonstrated that couples in which both spouses used marijuana frequently reported the least frequent IPV perpetration.” It was found that; “There was a significant positive association between wives’ marijuana use and wives’ IPV perpetration”, but “only among wives who had already reported IPV perpetration during the year before marriage.”

Researchers conclude; “These findings suggest there may be an overall inverse association between marijuana use and IPV perpetration in newly married couples”.
