Today, it's common knowledge that smoking cigarettes wreaks havoc on your health. But quitting smoking is also a wise choice for your wallet, and not just because you're saving money on packs of smokes. If one in ten American smokers quit, the U.S. would save an estimated $63 billion within a year. This figure considers the huge, rapid decline in health care costs that occurs after smokers hang up the habit for good. For example, California spent $15 billion less on medical costs in 2009 because that state has fewer smokers. On the other hand, Kentucky, which has a higher rate of smokers, had nearly $2 billion more in health care costs. We've collected some awesome videos on this topic. Watch them now to learn more.
