i guess my broad question shows my ignorance to it.

what i always wonder is how true it is that doing it just once gets you hooked. i mean, it seems crazy to me that there is that distinct of a flipped switch in your brain. unless it's just scaremongering, which seems more likely. i mean, i could see it being a slippery slope.. "well, i already did it once.. what's one more time...", but otherwise... :dunno:
