  • 8.6 million people live with a serious illness caused by smoking.
  • On average, smokers die 13 to 14 years earlier than nonsmokers.
  • Lung cancer is the leading cause of cancer death among both men and women in the United States, and 90% of lung cancer deaths among men and approximately 80% of lung cancer deaths among women are due to smoking.
  • Smoking causes many other types of cancer, including cancers of the throat, mouth, nasal cavity, esophagus, stomach, pancreas, kidney, bladder, and cervix, as well as acute myeloid leukemia.
  • People who smoke are up to two to four times more likely to suffer a heart attack than nonsmokers, and the risk increases with the number of cigarettes smoked. Smoking also causes most cases of chronic obstructive lung disease.
