Smoking is not as common in American as in many other countries. Generally, Americans smoke less than Europeans and much less than Asians. It is a practice that is becoming less and less socially acceptable.

Smoking is prohibited in many places. It is not allowed in any public buildings, on any public transportation (including airplane flights within the United State), in shops, in movies theaters, schools, and office buildings. The general rule is if you are indoors, then you probably are not allowed to smoke. The exceptions are bars, nightclubs, and some restaurants. If a restaurant does allow smoking, it will only be in an area that is designated for smokers. If you are with someone, even outdoors, it is polite to ask if they mind before you start smoking.
