I believe that addictive disorders must be treated first before an afflicted individual can truly recover.  Twelve Step Models like AA and NA are a recovery models that are, in my opinion, foundational to a person’s long term recovery and reestablishment of an orderly life.
The AA adage of “Don’t drink and go to meetings” is invaluable for people that are in the recovery phase of their addiction, but may be detrimental and even dangerous to people that are in the throes of an active addiction and may need medical attention.
