Don't know if there's a link, but just a story to share. After I detoxed, I gave AA a try, lasted just three meetings. I'd say at least 3/4 of them smoked like a chimney, and drunk gob's of coffee. The smoke at the entrance, well you could cut with a knife. So bad I would actual get physically ill. (I don't smoke or drink coffee) so I never returned. Not saying AA is bad, just an observation.
