I've always wondered this, about how one goes about getting into the harder, more addictive substances, that moment when a person decides, for the first time, to go ahead and do it -- be it heroin, cocaine, or whatever else. It remained a mystery to me for a long, long time until I finally did it myself, and I could probably argue that it was merely a slow slide from taking and abusing pharmaceutical, prepscription drugs to the similar (in their effects), more illicit, "street" drugs; and, to some degree, that might be true, but, in all sincerity, I simply made the decision to begin experimenting with those "taboo" sort of drugs. I made the decision, sought out those people and those substances, and then I did it.
