Everything in moderation. I know a few successful adults who have tried crack. Personally, I'd never want to try it but people can do what they want. I've been around people high on powder cocaine a few times and they were incredibly annoying.
This is the proper response. I'm sure heroin feels really really really good. The amount of addicts in this thread defending their addiction is surprising.
I have never used kratom, and I don't plan on it. But automatically assuming anyone who isn't hellbent against it is just a junkie "defending their addiction" is pretty close minded lol.
