After smoking was banned in bars, restaurants, and clubs in major U.S., European, and some Latin American cities, the city government of Rio de Janeiro has finally caught on.

The law, which goes into effect this month, prohibits smoking in enclosed spaces, both private and public. This means not only bars, clubs, and restaurants, but places like stairways, halls, and lobbies. It is intended to improve public health and provide clean air for Cariocas.

Bar and restaurant owners in Rio are up in arms and preparing to protest, since it could have a potential negative effect on profits. But public opinion shows that most people agree with the law–even smokers. Also, according to a survey, only 17% of Cariocas smoke.
