Doesn't seem to be making the slightest difference in my local. Except that it's a much more pleasant place to be. Same regulars, same numbers, the odd one pops out for a fag from time to time.

I'm sure there will be pubs where it will make a difference, for a time anyway. I mean, a pub where 90 per cent of the users smoked must have been a pretty extreme environment for the 70 or 80 per cent of the population who don't smoke, and they aren't going to change overnight the reasonable habit of giving it a wide berth. Give them time and they'll venture in, and the smokers are mostly going to adjust.
