The Great American Smokeout, sponsored by the American Cancer Society, is an annual event that encourages smokers to quit smoking on November 19, 2015. Despite a 50-year decline in cigarette smoking among U.S. adults, an estimated 20 million people have died from smoking-related diseases since 1964. About two-thirds of adult smokers want to quit, and more than half have made a quit attempt in the past year. However, in 2014, approximately 40 million U.S. adults still smoked. Effective counseling and medication can increase the chances of quitting by up to three times. Additional resources for quitting smoking are available through the CDC's Tips from Former Smokers campaign and by telephone at 800-QUIT-NOW (800-784-8669).The Great American Smokeout, sponsored by the American Cancer Society, is an annual event that encourages smokers to quit smoking on November 19, 2015.
