Can firing up a joint help prevent diabetes? Are stoners skinnier than non-stoners? A new scientific study suggests that, yeah, dude. Tooootally.

Regular marijuana smokers have better blood sugar control, which can reduce their risk of developing Type 2 diabetes, according to a new study from the American Journal of Medicine. Not only that, but the stoners studied had thinner waists and higher levels of "good" HDL cholesterol than non-tokers.

These results are a bit surprising given marijuana's famous side effects. But science!
