Please tell me anything you know about Narconon.?

I suggest that before you go anywhere near Narconon you contact a proper doctor to seek referral to a proper rehab program.

Narconon is a front group for the Church of Scientology. It is based on the doctrines of scientology's founder, L Ron Hubbard, a writer of bad science fiction with no qualifications whatsoever to deal with drug addiction. The program itself amounts to going cold turkey, and taking vitamin supplement and long saunas.

There is at least one poster on YA who had a bad experience with Narconon and will hopefully be along at some point to tell you about it.

In the meantime you may want to read this: http://www.cs.cmu.edu/~dst/Narconon/

All I know is it's a 12 step program-religeous based.
