People who smoke the green stuff once a week are about 25 percent less likely to be obese than non-smokers.

According to a study by French researchers, smokers have a 16 percent rate of obesity, whereas those who don’t partake enjoy a rate of obesity between 22 and 25 percent.

The researchers were surprised by these findings, since they assumed the “munchies” associated with use would actually make smokers fatter.

So they surveyed another sample group, and came up with same results. In fact, they found people who smoke at least three times a week have an even lower obesity rate (14 percent) then once-a-week.
