If all those warnings on cigarette packs aren't deterring you to kick the habit, then the CDC's graphic television spot will. It features personal stories from people dealing with the horrifying physical consequences of smoking.

The ads, which the CDC began running in 2012 as part of its Tips From Former Smokers campaign, may have prompted more than 100,000 smokers to stub out their addictions, according to a new study.
The study, led by a team at the Centers for Disease Control and Prevention, surveyed 5,300 Americans before and after the campaign, including 3,000 smokers. The paid ads ran for three months beginning in March, just after the New Year resolution season, when the percentage of smokers trying to quit is typically on the decline.

The researchers found that over all, four of five of smokers had seen the commercials, and the percentage who reported trying to quit rose by 12 percent. Of those who tried to quit, about 13 percent remained abstinent after the campaign had ended.
