Evidence that weed makes people ugly. (How can being ugly be a healthy thing?)
From Marijuana Detox website:
The skins of long-time weed smokers look like leather. In some, it also looks darker. Marijuana smoke contains many of the same carcinogens present in cigarette smoke. These inhibit the production of collagen. Collagen gives your skin its elasticity. Ergo, exposing your skin to reefer fumes ages you more rapidly. (Tell me you didn’t notice the sagging eyebags all smokers tend to have.) It can also worsen already existing skin conditions.

Willie Nelson after marijuana:
Willie Nelson mug shot. 1974. Busted for bag of marijuana. A real creep to this day.
