I guess I mean, changing environments after rehab.

The problem many recovering addicts face, is that even if they get to go to rehab, they return to the same stressful home life/enabling friends/underemployment that pushed them into addiction in the first place.

I guess what I'm saying is that rehab without job training/support and relocation assistance of some kind is doomed to high recidivism. (If the word recidivism applies to rehab, not sure if that's proper usage here)
