Based on well-known results, 12-step programs based on Alcoholics Anonymous and branching out to narcotics and such, appear to be extremely effective. However, since Jews are roughly a 1:100 minority in most of the United States (densely populated cities being an exception, of course), it's unlikely a Jewish alcoholic will be able to find a fully Jewish AA group.
Since AA requires surrender of control of our lives to "G-d as we understand Him", as one of the steps, religiously there should be no problem with a Jew's joining a non-fully-Jewish AA group.
Moreover, because one of the main rules in AA is to never encounter fellow members socially, there should be no danger of intermarriage from this. Am I right?
Is there anything else I should be concerned with when deciding to join such a group?
