Clean Indoor Air Act

The Maryland Clean Indoor Air Act (CIAA) of 2007 prohibits smoking indoors in public places, including restaurants and bars. The purpose of the act is to preserve and improve the health, comfort and environment of people in Maryland by limiting exposure to environmental tobacco smoke.
