Cigarette smoking harms nearly every organ of the body, causes many diseases, and reduces the health of smokers in general. Smokers are more likely than nonsmokers to develop heart disease, stroke, and lung cancer. Quitting smoking lowers your risk for smoking-related diseases and can add years to your life.
Cigarette smoking is estimated to increase the risk:
- For coronary heart disease by 2 to 4 times1,7
- For stroke by 2 to 4 times1
- Of men developing lung cancer by 23 times1
- Of women developing lung cancer by 13 times1
