Effects of marijuana use on impulsivity and hostility in daily life.

Due to a rising rate of marijuana use among young adults, there is a rising interest in how recreational marijuana use affects day-to-day experiences in users. A study published in March 2015 sough to examine the effects of marijuana on impulsivity and interpersonal hostility in daily life. The study followed forty-three participants with no history of substance dependence and monitored their moods using smartphone administered assessments.

Researchers found that on the day of and after marijuana use, participants demonstrated increased impulsivity and also demonstrated increased hostile behaviors, while perceiving high rates of hostility in others. The effects were independent of alcohol use and frequency of marijuana use.

This may be one route by which deleterious effects of marijuana are observed for mental health and psychosocial functioning. 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.
