On the nose! How often do smokers catch these diseases you point to Mr. Paulsen? The difference between Tobacco and marijuana, well there you go, one is legal. I guess if Marijuana were regulated like tobacco then the incidence of these fungal diseases might be even less than it currently is.
Ooooh, that's a mighty big "if".
So, until it's made legal, let's agree that the way medical marijuana is currently being "recommended" is dangerous and should be stopped.
