It would not bother me although I am a non-smoker. My wife, however, is really bothered (physically) by second hand smoke and is very anti-smoking. We have never been bothered by folks on the balcony next to ours smoking and I think there have been at least a couple times when someone who was a smoker was next to us. I think that the odds of it being a problem are very small, but I suppose it is possible.
