What you would really like to know is whether or not you'll become an addict, is that right, OP? And how about the powerball numbers? Hm? Would you like those, too?
Listen, no one here can tell you how likely it is that you will become an addict, and whatever experiences we have had with heroin really have no bearing at all on you and the experience you may one day have with it.
Are there people out there who can use heroin without becoming physically dependent and/or hopelessly addicted? Yes, of course, and there are also those people out there who do become the stereotypical, purse-snatching "junkies."
It's a total gamble, and not a gamble I would think worth taking. If you do decide to spin the wheel, throw the dice and give it a shot, well, then I sincerely hope that things work out for you, but I cannot imagine how terrible a feeling it would be to wake up one day in a motel room, dope sick, legs shaking, with just 46 cents on the nightstand and in that moment coming to the realization that you fall into the physically dependent, hopelessly addicted category. Oh, and then your next thought would of course be, "How am I going to get more dope with just 46 cents?" Yeah, that feeling would suck worse than you can ever imagine...
EDIT: I'm sending this thread over to BDD. It's not really a DC thread, but I'm not sure it's a BDD thread, either.
