In my experience in AA there is no "official" stance on it. The unofficial attitude is that people suggest reading the label on the Non-Alcoholic Beer and find out how much alcohol is actually in it. Then decide for yourself if it is worth the risk.

In my experience watching others I have seen too many people end up relapsing and drunk out of their minds from starting out with N/A Beer that I won't touch the stuff.

I hope this helps.

Rapid.
