Ok the term 'kill' isn't appropriate, but passive smoking exposes non-smokers to the same carcinogens as smokers and this would certainly cause a higher increase in various health problems, especially the long-term ones like cancer if you are exposed to it on a fairly regular basis.
When I used to be stuck in a room full of smokers, I'd temporarily have an irritable throat, nausea and a splitting headache. Of course everyone has different levels of tolerance and some people may not have any obvious physical effects.
The third hand smoking is a bit of a stretch I think, though my bf's mother has a separate bathroom in their house just for her smoking... and after years of it, the entire room is a sickly shade of orange brown

I accidentally stepped into the room once and almost freaked out coz it looked nasty. Everything was coated with the stuff. I know that's an extreme case though.
Our modern lifestyle does bring us into contact with lots of harmful chemicals, but I still wouldn't expose myself to a concentrated form of any chemical. We're already at high risk for cancer through so many means... why increase my chances?
I have nothing against people smoking, I just prefer if it wasn't around me. I don't mind the occasional contact with smoke, I just don't want to have to go to a restaurant, be on a plane etc and have to endure it for long periods. I think the smoking ban in public places is a great idea, but I do feel bad for smokers having to endure unpleasant weather and such to satisfy their habits.
There should be more 'smoking shelters' and the like for them.
