If I sit and have dinner at Smooky's Corn Blaster Shack one night, and there's smoke in the air, the worst that's going to happen is that my clothes will stink of it. The effect on my overall physical health will be no worse than what the corn blasters did to my upper GI.
Alcohol is another matter entirely. It can make anyone into a killer overnight.
Studies like the one I linked to in the first post of this thread disprove this. So do things like how people who work in businesses where there's lots of smoke in the air are more likely to get cancer. Second-hand smoke DOES cause cancer. And heart attacks too, it seems, going by this study.
