Narconon: A Residential Program with Merit?

I do not have the understanding or experience of being exposed to either scientology or narconon. 

According to Wikipedia, the free encylopedia found on the internet “the hypothesis underlying the program is that drugs and their metabolites are stored in the body's fatty tissues, causing the addicts cravings when partially released later, and can be flushed out through a regimen comprising elements such as exercise, sauna and intake of high doses of vitamins.” I would recommend you read the entire article plus do your own research. 

Here say is a flimsy foundation for commitment to a program sharply criticized by the medical profession. Why rely on theories of drug metabolism that are not widely supported?   

There are many Christian rehabs across the country. Again research on your part is necessary. There is no easy way to stop drinking alcohol or smoking pot. It takes time to get cuffed to any addiction. Discipline, structure,and the right kind of activity will lead to freedom just as the wrong discipline, the wrong kind of structure and the wrong kind of activity will lead you to the bondage of addiction.
