Study Finds Big Social Factor in Quitting Smoking

Smokers tend to quit in groups, the study finds, which means smoking cessation programs should work best if they focus on groups rather than individuals. It also means that people may help many more than just themselves by quitting: quitting can have a ripple effect prompting an entire social network to break the habit.

The study, by Dr. Nicholas Christakis of Harvard Medical School and James Fowler of the University of California, San Diego, followed thousands of smokers and nonsmokers for 32 years, from 1971 until 2003, studying them as part of a large network of relatives, co-workers, neighbors, friends and friends of friends.

Dr. Christakis described watching the vanishing clusters as like lying on your back in a field, looking up at stars that were burning out. “It’s not like one little star turning off at a time,” he said. “Whole constellations are blinking off at once.”

As cluster after cluster of smokers disappeared, those that remained were pushed to the margins of society, isolated, with fewer friends, fewer social connections. “Smokers used to be the center of the party,” Dr. Fowler said, “but now they’ve become wallflowers.”
