Maryland - The Maryland Clean Indoor Air Act of 2007

Statewide smoking ban: On February 1, 2008, the Maryland Clean Indoor Air Act of 2007 went into effect, banning smoking in all public transportation vehicles, enclosed public places, and enclosed wokplaces, including bars, restaurants, and private clubs.

The Act exempts private residences and vehicles while not being used as a childcare or healthcare facility, designated hotel/motel smoking rooms, retail tobacco stores, other tobacco-related workplaces such as importers and distributors, facilities where smoking research is conducted, psychiatric facilities, long-term care facilities, hospitals where a doctor has authorized a patient to smoke, and any business that has applied for and received a waiver allowing smoking (though all waivers expire on January 1, 2011). Local governments may regulate smoking more strictly than the state, though not less stricly.
