The success rate of AA is somewhere around 5-10%. Perfectly accurate stats are hard to acquire due to the nature of the disease of addiction, and the programs themselves intentionally do not track efficacy rate (after all, a program based on religious ideology instead of actual evidence has hilariously become the defacto prescription for drug addiction in the american legal system. Why ruin a good thing?). You would achieve a similar efficacy rate by giving addicts a sugar pill and telling them it was a miracle drug that cures addiction.

Also instead of taking the time to write out multiple comments expressing your doubt as to the efficacy of AA, you could've found the information you needed in a single google search.
