In California, it is illegal to smoke in any public accomodation: restaurants, bars, hotels, or workplaces. This is even in a room with a separate entrance and separate ventilation. Now bars have people dragging their kids in because no one smokes there anymore, so it's "family friendly". It's also illegal to smoke on any public property inside *or outside* - train stations, hospitals, courthouses, post offices.

This is past protecting the "health" of non-smokers, and into punishing smokers for having a habit that the antis have made socially stigmatized.
