The Irrationality of Alcoholics Anonymous
I read that article in The Atlantic. I disagree with almost all of it. There is no better or cheaper (it's free) approach to substance abuse for the motivated person.
It's not about "Does it work?" It's about "Does the person work it?" Sanity, like physical health, is not a passive enterprise.
Nothing can be done for the unmotivated person. However, some people on a downward spiral need a little rehab (ie forced abstinence) first to get a little clarity; some people benefit from naltrexone or topamax, and all benefit from treatment of any coexisting problems.
