Meh. I don't care much either way. Partly because I stopped smoking a few weeks back, but even before I started smoking I didn't generally care about other people's smoke if they're at least polite enough not to blow it in my face.

You can go overboard with anything, but I don't see much of a problem with people who smoke 1-2 packs a week (what I did). If you get cancer because of that little bit, you probably were geneticly inclined towards it. Sure all smokers die at an earlier age- but in a society where the economy suffers because the average age is on the rise, is that a bad thing?

Stop population ageing - start smoking
