“Despite the fact that the marijuana-induced “munchies” usually makes users eat more calories than non-smokers, users don’t appear to gain weight like people who don’t smoke.Researchers from the University of Nebraska, the Harvard School of Public Health and the Beth Israel Deaconess Medical Centre studied more than 4600 adults.Twelve percent of the participants were current marijuana users and 42 percent said they had smoked cannabis in the past.

The researchers tested their insulin resistance, cholesterol levels, waist circumference and fasting insulin and glucose levels, and found the pot smokers scored significantly better than the non-smokers, even after they’d factored in other risk factors, such as age, sex, physical activity, alcohol and tobacco use.

The smokers’ insulin levels were 16 percent lower and their insulin resistance was reduced by 17 percent. Insulin resistance is a condition where the body can’t effectively absorb glucose from the blood, and is linked with weight gain.

The pot smokers also had more good cholesterol.

The 42 percent who used to smoke also scored better, however the results were not as significant as the current smokers.

The authors said they’re not sure why it happens, however said the fact marijuana seems to aid insulin regulation and reduce fat gain could also explain why marijuana smokers are less likely to have diabetes”
