Most addiction recovery programs are based on the AA 12 Step nonsense.

"AA’s actual success rate somewhere between 5 and 8 percent."
If addicts want to clean up, they'll clean up.
Show me a heroin user, Anywhere in America who hadn't heard about what the stuff was before they started using.
Considering that at its basic self, AA is a voluntary program, you'd expect the success rate to be higher.
But there's a problem:
Not all people are there of their own volition. (Not all the people in treatment programs are there because they want to quit.) A tremendous number are there because they have been court ordered to attend AA meetings, either as part of their court ordered treatment, or part of their sentence.
Wanting to quit is probably the single most important thing in a successful treatment program, because, ultimately, someone who doesn't want to quit (entirely) will find a way, find an excuse, just this once, to go back to it.
Believe it or not, those court-ordered people often sit around and talk abut how much they miss being out, and their plans to tie one on when they get there, at least according to people I have known who did get in trouble and end up in treatment facilities because the 'evaluation' people found them to be Alcoholics or Addicts.
You'd hear them talking about it down at the bar. Of several dozen people I have known who got DUIs, only two were not judged by the evaluation people to be Alcoholics. They were not all heavy drinkers.
These were people who held down jobs and raised families and generally maintained, but who didn't that time, or were just slightly over the limit, for the most part. Did they drink regularly? Yep. 2-3-4-5 beer a night, after work, after dinner. Did they have a 'problem' with alcohol? In my unprofessional estimation, some did, some didn't. I think the evaluation people were very aggressive in their interpretation of who was an "alcoholic".
I think if you were to take the people who showed up at AA because they actually wanted to quit, the numbers would be considerably higher.
