A pair of recent studies suggest that marijuana policy reform may be paving the way for a healthier, happier world in at least two ways.
The first, released by the University of Buffalo, found that couples who use marijuana are the least likely to engage in, or be the victim of, domestic violence and abuse.
The authors caution that while these findings are predictive--meaning couples who smoke are less likely to commit domestic violence--they don't necessarily draw a causal line between the two behaviors. Among the connections they hypothesize, "marijuana may increase positive affect, which in turn could reduce the likelihood of conflict and aggression." ...
Another possible mechanism: "chronic [marijuana] users exhibit blunted emotional reaction to threat stimuli, which may also decrease the likelihood of aggressive behavior."
The second study, published in JAMA Internal Medicine, reported that states with medical marijuana laws have roughly 25% fewer painkiller overdose deaths than states which do not allow medical marijuana. While the authors caution that this could simply be a correlation, not a causal effect, a large amount of anecdotal research exists from patients who report weaning or discontinuing their use of prescription painkillers once they are able to use marijuana to treat their conditions.
