on a side note, i have tried shrooms once and opium 2x (which are considered "harder" drugs). but, i haven't had the slightest craving to ACTUALLY do hard shit like meth, ecstasy, heroin, etc. the shrooms were completely different (entirely visual), and the opium was too intense in my opinion (severe high - but you REALLY can't move).
only shrooms would i ever do again.
and i don't consider pot a gateway drug. i feel that if anyone is willing to try it to begin with, they usually are willing to go further (so although its the first they try, its not because of pot that they go further).
whatever, just my opinion.
