California prohibits smoking in buildings open to the public. You get used to it if you live here.

When you are in many US states outside California or are in Europe or Latin America people smoke in restaurants, and more or less everywhere including medical offices or hospitals. 
I visited a Chinese hospital a couple of years ago and literally everyone including the medical staff were smoking. There was no ventilation on the ward and the place felt as if somebody was piping automobile exhaust directly in. I found it odd.
I don’t smoke, so there you have it. My prejudice is exposed!
Where do you feel your rights begin and a smoker’s rights end (if you don’t smoke). If you do smoke, do you feel that there are places where it would be better not to light up? Have you ever considered smokeless tobacco? If you are a non-smoker, have you ever had the urge to kiss somebody who is chewing tobacco? (curious)
