Success in the city: the road to implementation of Tobacco 21 and Sensible Tobacco Enforcement in New York City.

New York City, a leader in municipal tobacco control in the USA, furthered its goal of reducing the community's burden of tobacco use in 2014 by implementing Sensible Tobacco Enforcement and Tobacco 21. These policies are intended to restrict youth access and eliminate sources of cheap tobacco. Strong partnerships, substantial local data and support from the public and elected officials were key in overcoming many challenges and ensuring these policies were signed into law.
