Just a random comment on the smoking thing, since I don't have anything to add on the other subjects:
Down here they've been steadily reducing the indoor places where people can smoke. Public buildings, restaurants, etc. You can easily go for a long time without inhaling any secondary smoke.
A year ago, I visited Las Vegas (we flew in and out while visiting national parks in AZ and UT, spent a day there at the end). You can smoke anywhere in Vegas, and people do. Now, I smoked for a few years. Never more than two or three cigarettes (not packs) a day, and I quit four or five years back. But breathing in the casinos was absolutely horrible. I just could not stand it at all.
Outside, in your own home, whatever. But secondary smoke in enclosed places is nasty, especially if you've been free of it for a long while.
