Some 45 million people in the U.S. are smokers, and 69 percent of them want to quit, according to the Centers for Disease Control. Seven out of 10 smokers say they've tried at least once to quit -- and failed, says Dr. Michael Fiore, director of the University of Wisconsin Center for Tobacco Research and Intervention. For those who go cold turkey -- and don't replace smoking with food or shopping -- costs may be minimal. Otherwise, costs can mount, though you'll save as much as $4,300 a year if you were a pack-a-day smoker.
