People Who Consume Cannabis Are Slimmer Than Those Who Don't, Says New Study

Got the munchies? If so, try not to worry too hard about the extra calories; you’re probably already slimmer than your non-cannabis smoking friends, anyway – at least according to a new study.

Researchers at the University of Miami found that people in their study who smoked cannabis every day had a roughly three percent lower BMI (body mass index), on average, than those who didn’t smoke at all. 

"There is a popular belief that people who consume marijuana have the munchies, and so [they] are going to eat a lot and gain weight,” lead study author Isabelle C. Beulaygue, a research support specialist in interventional radiology at the University of Miami, told LiveScience. “We found that it is not necessarily the case.”

The study focused on 13,000 people between the ages of 18 and 26 - people who consumed cannabis and those who didn't. The researchers calculated their BMI and then tested them for marijuana use. They checked in again six years later and measured the change (if any) in their BMI and tested them again for cannabis use.

The researchers discovered that the BMIs for the women who smoke marijuana were 3.1 percent lower than women who didn't. The men who consumed cannabis had BMIs that were 2.7 percent lower than the men who didn't.

The study was published in the September edition of The Journal of Mental Health Policy and Economics

Because it has been illegal or stigmatized for decades, the body of cannabis research available is, in many ways, incomplete. But Canada’s federal government is taking advantage of the country’s status as the only G7 country to have legalized marijuana and addressing that issue. It was announced yesterday that nearly 25 million dollars will be used to fund cannabis research in Canada.
