Being a recent ex-smoker (5 months yesterday), I still have no problem with smoke and smokers. Maybe I still enjoy the smell of them, I'm not sure. As long as there are smoking and non-smoking sections, I don't have an issue.
Smoking outdoors is no problem. It is ridiculous to make that illegal.
However, I have always said that if I became one of those obnoxious ex-smokers, to shoot me.
BTW, if smoking does bother you, don't go to Vegas. The smoking was so bad there (there seem to be no restrictions) it even got to me.
