I don't believe there is a single meeting in this town that allows smoking.
When I got sober fifteen years ago, I think about three-quarters of the meetings in my town allowed smoking, now I don't know of any. Many have been told by churches that smoking is no longer allowed, and it usually isn't a problem (it's not like there are a lot of places to hold meetings that will allow it). What churches usually have to do though is get on the people at the meetings about not leaving cigarette butts in the parking lot.
