The Boston Parks and Recreation Commission on Monday approved a ban covering the 251 parks, squares, cemeteries and other spaces run by the Parks and Recreation Department, including Boston Common, the Public Garden and Franklin Park. No one spoke in opposition to the ban.
The ban takes effect immediately and applies to tobacco, marijuana and other "lighted or vaporized" substances. Violators face a $250 fine.
The City Council approved the measure last month.
"This amendment is necessary to maintain the health and safety of our public parks and ensure that these valuable resources can be enjoyed by all Boston residents," Mayor Thomas Menino said in a letter supporting the ban.
