Those who use marijuana, commonly associated with “the munchies” or increased appetite and the likelihood of weight gain, actually have a lower body mass index (BMI) than non-users, according to the results of a new study from the University of Miami School of Business Administration and Miller School of Medicine. The findings, published in the September issue of The Journal of Mental Health Policy and Economics, shows that daily female marijuana users have a BMI that is about 3.1 percent lower than that of female non-users, and that daily male users have a BMI that is about 2.7 percent lower than male non-users. BMI is a measure of body fat based on height and weight, used to classify overweight and obesity.
Researchers controlled for several other factors that could potentially correlate with BMI. The demographic variables included age, race, ethnicity, employment status, and marital status. They also controlled for cigarette smoking, other substance use and alcohol consumption, as well as measures of weekly exercise and self-rated health status.
