Amidst the deluge of new studies coming out that seem to champion the benefits and health potentials of cannabis, there’s always a few that strike a discordant note in the chorus of positive findings.
Interestingly, one of these new studies points to a behavioral change that marijuana seems to be causing in some users.
According to the study, published by researchers at Yale and Pennsylvania State, marijuana may lead to a surprising change in behavior among users.
Initially published online in January 2015, a study from researchers at the Yale University of Medicine and Pennsylvania State University showed that trial participants who smoked marijuana tended to be more hostile and impulsive the day they used marijuana, as well as the day after.
The study’s abstract reads, “marijuana use was associated with increased impulsivity on the same day and the following day relative to days when marijuana was not used, independent of alcohol use.”
The study also found that “marijuana was associated with increased hostile behaviors and perceptions of hostility in others on the same day when compared to days when marijuana was not used.
The study used the technical term hostility as a blanket term for emotions like grumpiness or irritability.
The study only looked at 43 young adult subjects, so hardly a significant sample size. That’s why the study’s authors are calling for more research into the behavioral effects of marijuana on everyday life.
“Given the increasing prevalence of recreational marijuana use and the potential legalization in some states, further research on the potential consequences of marijuana use in young adults’ day-to-day life is warranted,” the study concluded.
Just because marijuana users in this small sample proved more grumpy or hostile doesn’t guarantee that marijuana was the ultimate cause, which is why additional studies are needed.
It’s important to note these negative indications, however, so that future studies can debunk them and remove their conclusions from being obstacles on the path to full legalization.
