I have tried crack meth and heroin. I absolutely did not like crack. It was an overwhelming flight or fight rush and it lingered with me through out the day. I do not see it as recreational or even enjoyable, so certainly did not become addicted after one use. Heroin was fun and I think I handled myself quite well on it, I didn't get addicted etc but I have seen heroin fuck peoples lives up and it is bad news. Meth is highly addictive and I would suggest against it, I still get cravings for it to this day many years after trying it last and after never having been a heavy user.
