A 2019 study from the University of Colorado Boulder looked at the relationship between marijuana usage and exercise habits, and contrary to what you’ve seen in movies, people who get high regularly are not necessarily lazier than those who abstain from the drug. “There’s some really good longitudinal data that shows that long-term cannabis users have lower weight, lower risk of diabetes, better waist-to-hip ratio, and better insulin function,” Angela Bryan, a psychology professor at CU Boulder, told Westword. Long-time weed smokers are also creatively productive, if Seth Rogen is any indication.
