Aloha, Don't know where in the world you found the 5% quote? Its widely known that AA has the highest success rate of long-term recovery thats why so many other organizations pattern their programs after the twelve steps. Equally amazing is that its free... Of course no program will work if the person isn't committed to staying off the stuff. AA really doesn't focus much on the "why" someone abuses alcohol just that they do and its a problem for them. But... I guess I'm a little bias... it saved my life and I've been sober and clean from IV drug use for 34-years. Best wishes in your quest
