Narconon is a Scientology run help center for drug addiction which may seem like a positive thing on the surface but it is used as a recruitment tool yes. Avoid these people they are members of a scam based organization. I would use you tube and Google to identify as much information as you can to educate yourself about these people. While searching for narconon i found one site which gives great information regarding rehabilitation process that is
Rob's Ranch and after visiting it i am fully satisfied and now i can understand every rehab process.
