>> They do it because it feels amazing.
Heroin doesn't feel amazing. People say it does, but most of the time, it just knocks you off. I took the stuff maybe a dozen times or so, many years ago. I remember stumbling about town and falling asleep at cafes and bars, completely oblivious of what I looked like (an accomplished idiot, off my tits and completely ridiculous).
I remember a friend who was a full-on junkie, who used to say that heroin hooks you because it makes you very sociable and pleasant. Well, my experience is that, after he shot up, he would fall asleep on my bed. My mother would come in the room and ask why he's asleep and me and my other pals would tell her he's tired from work, him snoring throughout. But, you know- it makes you sociable, fun to be around, a real party animal.
(Edit: the other thing people say is that it makes you good at sex. Sure, except you can't get it up. But other than that, yeah, great sex.)
Delusional is what it makes you. You think it's making you feel good. All it does is make you feel nothing. If something hurts, I guess that feels "good". But if there's nothing broken in you, there's nothing you can get from this shit. Nothing.
Incidentally, my snoring friend died a few years down the line from a heart attack, at 34. Another friend became an addict and he's constantly in and out of detox communities since then. It's sad and it's not worh it. And I don't understand how it hooks you, because it just sucks. I stopped doing it because it was boring and pointless. If it was any good, I'd have been addicted too. But it's not. It's just dumb.
But, you know. If you're Nikki Sixx, then maybe you can have a great time even on heroin. I bet I would.
