I quit in Feb 2001 (wow, been a while now), after smoking 2.5 packs a day for 10+ years.
I tellya, I can really smell it when I enter the home or car of a smoker. I bet it's a lot worse for ex-smokers, because we were so used to it.
Now, I doubt it would keep me from buying a house, since you can air it out and clean it. But a car - maybe. The smell gets in the upholstery and stuff, and as an ex smoker, you just don't need that reminder.
I got no problem with people smoking, especially outdoors. That's just ludicrous. I'm not one of those facist anti-smokers. I would recommend folks quit though - it's not that hard if you just make up your mind
