The "munchies" aside, pot smokers are actually less likely than non-tokers to be obese, according to a study by a French researcher.
The examination of data from two separate studies of more than 50,000 U.S. adults found that 14% to 17% of people who smoked pot at least three days per week were obese, compared with 22% to 25% among non-cannibis users.
The research team headed by Yann Le Strat, a psychiatrist at the Louis-Mourier Hospital in Colombes, France, appears in theSept. 15 issue of the American Journal of Epidemiology.
"Initially, we thought we made a mistake," says Le Strat, according to Reuters. He says he and co-author Bernard Le Foll checked the results several times to make sure they were correct.
"This is only a preliminary result," he says. "It doesn't mean that marijuana does actually help you lose weight, but perhaps there is a component that does."
The researchers did not examine whether diet and exercise habits were different between the two groups but did find that cigarette usage had no influence on the obesity findings, Reuters reports.
