As far as tobacco smoking, the nanny state is operative in all U.S. states and many countries. I fondly remember flying commercial when you could light up a few seconds after wheels-up. Nowadays, few countries are civilized enough to even have a smoking area inside a terminal. I’m told that Israel has them.
There is one at Dulles, terminal D, all the way at the end. .
And the non-smoking passengers on the plane unfondly remember breathing your smoke and then having to take their clothes to the cleaner.
