Cannot speak for heroin or crack. And I have not studied any kind of neurobiological thing under anybody.
But I did do a bit of experimenting, shall we say, all long ago.
Cocaine seemed to have no effect at all, except to make me smarter, braver, wittier, more optimistic, and much, much more productive. It did all this in a subtle enough way, because I was never rich enough to do lines and lines (although friends of mine were). Cocaine was just that perfect little pick-me-up when I wanted to go out after a 14-hour workday, for instance. Or, for instance, in hour 10 of the 14-hour workday.
Crystal meth was the same except with a rush and much bigger sense of urgency, not to mention that instead of making me just a little smarter it made me much, much smarter than everyone, even the people around me who were also snorting crystal.
I am a person who has a lot of ideas that I think are brilliant at the time, but then I never have enough follow-through to even get them started. Coke and crystal both provide the follow-through.
Now, while I didn’t do it a lot, I was addicted enough that I could get some of the effect merely by making the deal. Being not very rich I never could afford a whole eight-ball of coke, or usually even a whole ounce, but I knew plenty of people who would go in on it, if they had the money. Spend the morning on the phone, get however many people needed to go in on it lined up, savings accounts raided, CDs cashed in or whatever, the deal arranged–it was as good as taking the drug.
Not surprisingly, a lot of the people I knew who were rich enough to toot a whole ounce–or more-- in a single night got into some trouble, and without exception they signaled the onset of the trouble by complaining (or apologizing) about the quality of the product, as if they’d been ripped off (and I am talking here about people who spent $400 a week on the stuff). So, the first time I heard myself complaining that this just wasn’t very good shit I’d just bought, and apparently it had really been stepped on, I thought I might be headed for trouble, and I never bought it again.
And I spent ten years missing it. This, from a pretty casual user. Not missing a LOT but more like, “Hey, this would be a good time for some coke . . . except I don’t do that any more . . . bummer . . .”
By the way, I never got any effect whatsoever from chicken. Is one supposed to snort it, or just eat it as usual? I think this may be an urban myth.
(Disclaimer: I might have an extremely addictive personality. Must have coffee before brain works in morning, and got sicker for three days giving up Mountain Dew than a friend of mine did who spent those same three days going off Paxil.)
