Anybody who’s smoked marijuana knows about “the munchies,” that desire to eat everything within reach. But a study from France has found that, surprisingly, pot smokers are actually less likely than non-smokers to pack on weight.

Using data covering more than 50,000 U.S. adults, researchers headed by Yann Le Strat, a psychiatrist at the Louis-Mourier Hospital in Colombes, France, found that roughly 14 percent to 17 percent of the people reporting that they smoked pot at least three days per week were obese.

That compared with a 22 to 25 percent obesity rate among people who said they had not used pot in the past 12 months.

“Initially, we thought we made a mistake,” said Le Strat, adding that he and co-author Bernard Le Foll checked the results several times to make sure they were correct. “This is only a preliminary result. It doesn’t mean that marijuana does actually help you lose weight, but perhaps there is a component that does.”

I hope someone lets us all know when they want to run further studies in the United States. There will only be about 150 million volunteers.
