This old column about Marijuana and the Munchies is outdated. Unique Cannabinoid receptors have more recently been discovered in the brain.

Sure, we could use a current column on cannabis, but that one hasn’t been proven false. Marijuana (and the cannabinoid system) doesn’t affect your blood sugar levels except in that it changes your eating habits.
The point isn’t that the last column was “wrong.” If you look at the article I cited, you’ll see that there is a lot of new, interesting information about receptors in the brain that are specifically triggered by cannibis.
