Avoid rehab at all costs. I'd rather go to jail/juvie than go to rehab. Its terrible, it's basically ATI to the fullest. Like Marevix said, if you do go, fake it. You might get tested, you'll most likely sit in a circle with other "substance abusers" and talk about your problems with "marijuana."

"Now, how does that make you feel?"

Its just like ATI and Dr.Phil combined.
