In my country it seems like the vast majority are alcoholics; at least we're constantly close to the top of the charts in alcohol consumption, and the drinking culture is one where getting shitfaced is both the only way to drink and is socially acceptable, and makes for perfectly normal Monday-morning talk at the office. Bosses will laugh off workers not coming in Monday because of a hangover (as long as it doesn't happen too often).
Then people say "Man, can't you get fucked up enough on booze? Why do you need other shit?"
I can and do get fucked up enough on booze. I get TOO fucked up on booze. I don't wanna be all messed up, I wanna mellow out and smoke a joint.
Then these same guys always talk about the risk of psychosis and schizophrenia and the "fact" that since it's lipophilic, it stays in the body for ages and might unprovokedly get you high and make you "hallucinate" a month after use. 8)
These kinds of beliefs are stunningly common, even among young people. I've also heard that "alcohol is water-soluble, so it's safe. THC is fat-soluble, so it's dangerous". What the fuck? Lipophilic = dangerous? Plenty of vitamins, such as vitamin B, are lipophilic.
