Smoking is really bad for you. Most people know that. Even smokers think smoking is bad for one’s health. But most people don’t know just how bad it is.

More people in the United States die every year from smoking than from alcohol, illegal drug use, car accidents, suicides and murders combined. Cigarette smoking costs an estimated US$240 billion annually in health care costs, which harm not only smokers but also nonsmokers, communities and the economy. Smoking is the top preventable cause of death and disease in the U.S. and worldwide.
