Marijuana Users Weigh Less, Defying The Munchies

New evidence from Michigan State University suggests that those who smoke cannabis, or marijuana, weigh less compared to adults who don't.


The findings, published in the International Journal of Epidemiology, are contrary to the belief that marijuana users who have a serious case of the munchies will ultimately gain more weight.

New evidence from Michigan State University suggests that those who smoke cannabis, or marijuana, weigh less compared to adults who don't.

"Over a three-year period, all participants showed a weight increase, but interestingly, those who used marijuana had less of an increase compared to those that never used," said Omayma Alshaarawy, lead author and an assistant professor of family medicine. "Our study builds on mounting evidence that this opposite effect occurs."


Results also suggest that new and persistent users are less likely to be overweight or obese, overall.


"We found that users, even those who just started, were more likely to be at a normal, healthier weight and stay at that weight," she said. "Only 15% of persistent users were considered obese compared to 20% of non-users."


Researchers used data from the National Epidemiologic Survey of Alcohol and Related Conditions and looked at the Body Mass Index, or BMI, of 33,000 participants, ages 18 and older, then compared the numbers.


While the actual weight difference among users and non-users was modest, around 2 pounds for a 5-foot-7-inch participant weighing about 200 pounds at the start of the study, the variance was prevalent among the entire sample size.
