Starting Monday, smoking is no longer allowed in any of Seattle’s 465 public parks. The city’s Board of Park Commissioners unanimously voted for the ban in May, according to a statement on Seattle.gov. The city of Dearborn, Michigan, is expected to do the same, CBS Detroit reported Monday, though the proposal hasn’t been approved.

Seattle’s new rule is an update to an old policy that banned smoking within 25 feet of nonsmokers, King 5 News reports. Smokers won’t be kept out of the parks, and violators won’t immediately be cited for smoking. Instead, park personnel will approach smokers and ask if they know smoking isn’t allowed in the parks, and will then give them info on where they can smoke and resources for quitting. Despite this warning system and lack of citations, KOMO News reports that police may still arrest people caught smoking.

Dearborn, a Detroit suburb with 43 public parks, has also proposed a ban on all forms of smoking, including cigarettes, e-cigarettes, cigars, and hookahs, according to CBS Detroit. Smokers would not be ticketed right away but could be fined $25 if they don’t heed police warnings to stop smoking. Dearborn’s city council will consider the ban on July 23.

About 1,000 other cities in the country, including New York and San Francisco, already ban smoking in public parks.
