In the US, New York City took its smoking prohibition outdoors, adding the city's parks and beaches to the list of places where lighting up is off limits.

It's part of Mayor Michael Bloomberg's campaign to promote healthy habits. The campaign aims to prevent problems caused by second-hand smoke. And the latest move extends the city's 2003 ban on cigarettes in bars and restaurants. It includes the city's 1,700 parks, beaches, boardwalks and pedestrian plazas, such as Times Square.

Violators face a 50 dollar fine, but officials say the ban is meant to be largely self-enforcing. Residents shared their thoughts.
