Quack (for-profit) unregulated for-profit rehab facilities should never be taken at face value, especially if you expect proper care and supervision of all clients to prevent deaths and multiple relapses.

As for cults posing as rehab/recovery places, DO NOT take the bait and run away instead. Always do your R and R's (read and research).
