Addiction - Once you are off heroin, which drugs do you think are likely to cause a relapse?

[dyingtomorrow]

SWIM was wondering what people thought about this. SWIM's just going to throw a bunch of shit out there about different drugs and would like to hear other people's perspectives.

SWIM, for instance, when he drinks, actually loses the desire to do heroin. However, 1 of the 2 times he got fully clean, he relapsed because of a bad hangover.

He knows an ex heroin addict who says marijuana keeps him from using. SWIM doesn't like pot that much anymore, so doubts it would work for him.

When SWIM has done mushrooms before, even though he was on heroin, he found himself having a markedly decreased desire to do it. He would assume the same of other psychedelics.

Drugs like DXM and Ketamine he hears actually decrease cravings and addictive behavior (for opiates).

On the other hand, drugs like cocaine, crack and meth he thinks are very likely to cause a relapse. One guy at the last rehab he was at stayed clean for a year, did meth one night with his cousin, fucked her, and then relapsed the next day (I'm sorry, but LOL).

As for ecstasy, the drug he wants to do the most next to heroin - no clue. Would especially like to hear other people's thoughts about it.
