Lighting up a cigarette in any Boston park — including the iconic Boston Common and Public Garden — may soon draw a $250 fine.

The city council last week approved a ban on smoking all 250 of the city’s public parks, cemeteries and other spaces and Mayor Tom Menino is expected to sign the measure soon. Before it takes effect, the ordinance will have to pass a vote by the city parks commission, which is expected to approve the measure next month.

City officials say the ordinance will reduce the harmful effects of secondhand smoke, curb litter, and help pressure smokers to kick the habit.

Similar ordinances are in place in other major American cities.

Smokers says the measure goes too far.
