Until recently, cannabis has never had a good reputation when it comes to obesity and weight gain. Mounting evidence shows cannabis is not associated with an overweight body mass index, and there is now a new piece of research to add to this list. In a longitudinal study from Denmark that surveyed adolescents aged 15-19, and then surveyed participants again 20 years later, researchers took into account marijuana, cigarette, and alcohol use, along with height, weight, physical activity, and other confounding factors. After adjusting for factors like tobacco and alcohol use, and exercise, they found participants who smoked marijuana were not more likely to gain weight later in life than those who did not. They also found those who began smoking as adolescents actually had the smallest increase in BMI.

While these results are promising, the study was not perfect. Thousands of participants dropped out of the study between the initial survey and the followup survey, and the study relied on trusting participants to self-report truthful data. That being said, researchers noted survey takes tend to under-report the amount of cannabis they consume, which could mask an inverse relationship between smoking cannabis and BMI. Additionally, there are several other studies that report similar findings.
