I don't know... what I do know is that drinks/drugs are but a symptom of the real problem, and it requires constant work to "recover" from that problem... once you stop working the problem resurfaces and inevitably will lead the person back to using/drinking (they might can stay sober, but it's a miserable kind of sober). I know that in the program that I am in, I was told that there is no graduation. Just my 2 cents
