Also, it seems that smokers (at least in the US) are much more likely to go outside to smoke now, even when at their own home. Sorry, no data just personal recollections from childhood in the '80s.
This seems correct anecdotally. At some point they figured out that smoking is somewhat less bad for you if you smoke outside, so maybe this had some effect.

Smoking is in no way less bad for you if done out of doors. It's because no one, not even a smoker, wants their domicile to smell like an ash tray...and when selling a house, you don't want to cut out that large swath of the population that doesn't smoke from your buyer pool.
