The Boston Parks and Recreation Commission decided yesterday you can no longer light 'em up, up, up in city parks and playgrounds.

In a unanimous vote, the commission set a $250 fine for anybody caught lighting up a cigarette or other inhalable substances. Although the ordinance, also approved by Mayor Menino and the city council, goes into effect immediately, city officials will hold off actual enforcement until after a public-education drive in the new year.

The amendment to City of Boston Municipal Code, Ordinance 7-4.14, prohibits the smoking of tobacco, marijuana, or any other material on properties controlled by the Boston Parks and Recreation Department.
