Virginia ? The home state of Marlboro and the world’s largest cigarette factory is banning most smoking in restaurants and bars.

Virginia Gov. Tim Kaine signed a bill Monday that generally restricts smoking to separate rooms that have their own ventilation. It takes effect Dec. 1.

Kaine had been working for years for a total ban on smoking in all restaurants but compromised with lawmakers in the bill that passed last month.

The measure also exempts private clubs and open-air outdoor areas of bars.

The first substantial tobacco curb is remarkable, however, in a state that began growing tobacco at Jamestown 400 years ago and is home to Philip Morris and its Marlboro cigarette factory, the world’s largest.
