Used all 3 heavily in the past. Heroin was my first love. Did it for a long stretch and was able to relatively keep my shit together. There's a romanticism to it, it's more distinguished. It really is something special and on some level, I dont blame anyone who chooses to throw their life away by using it until they're dead. It's that good.
I still think about this monologue a junkie gave to me the first time I went to detox about how heroin feels like love and everything you've been missing your entire life, the warm embrace and comfort that finally makes you whole. It's true, and having that kind of singularity of purpose and focus on one thing is so liberating. Nothing else matters. I can vividly remember that feeling, being completely at ease with my circumstances. I've never related to the people I was surrounded by more than when they were all dope users like me. It was such a unifying bond.
Meth and crack will turn you into a punchline, a fool. You'll be a fucking animal trying to get more of that shit, not just a soulless addict in withdrawal. There's nothing poetic about it, no feeling of deeper meaning behind it. I will say though, a heroin and meth speedball is the absolute pinnacle in the drug world in my opinion. That's what finally made me crash and burn with the quickness, shooting those every day. That shit had me thinking everyone was an undercover cop, staring through hotel door peepholes all fucking night, looking all over the floor for drugs I thought I dropped but really it was just garbage. Just as pathetic as it gets.
