New York smokers have been sent outside in all kinds of weather, coughed at in disdain, and now they are burdened with the most expensive cigarette taxes in the nation.

Now, to add cost to injury, the state is declaring its highest-in-the-nation cigarette tax a success.

The number of calls to the state’s Smoker’s Quitline quadrupled to nearly 10,000 calls during the week of June 2, when the full $2.75-a-pack tax kicked in, New York Health Commissioner Dr. Richard Daines said. Fewer than 2,300 people called for help during the same week in 2007.

The urge to smoke is contagious, but quitting apparently is, too. A team of researchers who showed that obesity can spread person-to-person has found a similar pattern with smoking cessation: A smoker is more likely to kick the habit if a spouse, friend, co-worker or sibling did.

What’s more, smokers tend to quit in groups and those who don’t stop puffing increasingly find themselves pushed to the edge of their social circles, the researchers found.

“Your smoking behavior depends upon not just the smoking behavior of the people you know, but also the people who they know” and so on, said Dr. Nicholas Christakis, a medical sociologist at Harvard Medical School and lead author of the new report.
