Doesn't matter whether it's Al Anon or Nar Anon. Like everyone else has said, you qualitfy for either one. A drug is a drug is a drug and my particular Al Anon group doesn't care what it is the person is drinking or taking.
So I say RUN, don't walk to the next Al Anon meeting! And promise me you'll attend AT LEAST six meetings. You can't judge a meeting or the people by one or two meetings.
