Young New Yorkers would not be able to buy cigarettes until they were 21, up from the current 18, under a proposal advanced Monday by Dr. Thomas A. Farley, the city’s health commissioner, and Christine C. Quinn, the City Council speaker.

The proposal, which would give New York the highest smoking age in the country among major cities, is the latest effort in a long campaign to limit smoking that began soon after Mayor Michael R. Bloomberg took office, with bans on smoking in restaurants and bars, and expanding more recently to bans at parks, beaches, plazas and other public places.

Given some of the responses to New York’s last major health initiative, we imagine more than a few residents won’t be particularly fond of the proposed change; however, it is likely to see some support. Thoughts?
