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.
