Are You Looking At My Pint?

The smoking ban (in public places, at least) has had a weird effect. I don't smoke, but I could at least live with the smell and pollution - now, after 2 weeks of holiday and a month or so of the ban being in place, I feel nauseous every time someone lights up around me. It's not a psychological reaction to the act of lighting up, but a response to the smoke itself.
