ANTHONY KIEDIS of Red Hot Chili Peppers

The singer, who successfully overcame an addiction to heroin, spent many years going in and out of rehab and has remained clean since the beginning of the decade (00).

He says, "Rehab is full of a lot of quacks that want to instantly diagnose you as this or that, or with something you might not actually have, just because you're on a bad drug run or something.

"Then you show up and suddenly they decided you're manic depressive. If you wanna get well, you'll find a way."
