Smoke from tobacco contains more than 7,000 chemicals. Hundreds are harmful and many cause cancer. Smoking increases your risk for serious health problems and diseases. However, people who quit stand a chance at reducing their risk for disease and early death. The earlier you stop, the greater your health benefits are. You are never too old to quit smoking cigarettes!
Health benefits of quitting
Lowered risk for lung cancer and many other types of cancer.
Reduced risk for heart disease, stroke, and peripheral vascular disease (narrowing of the blood vessels outside your heart).
Reduced heart disease risk within 1 to 2 years of quitting.
Reduced respiratory symptoms, such as coughing, wheezing, and shortness of breath. While these symptoms may not disappear, they do not continue to progress at the same rate among people who quit compared with those who continue to smoke.
Reduced risk of developing some lung diseases (such as chronic obstructive pulmonary disease, also known as COPD, one of the leading causes of death in the United States).
Reduced risk for infertility in women of childbearing age. Women who stop smoking during pregnancy also reduce their risk of having a low birth weight baby.
Among U.S. adult cigarette smokers, nearly 7 out of every 10 report wanting to quit completely.
The percentage of daily cigarette smokers trying to quit who stopped smoking for more than 1 day:
More than 5 out of 10 (55.4%) of all adult smokers
Nearly 7 out of 10 (66.7%) smokers aged 18–24 years
Nearly 6 out of 10 (59.8%) smokers aged 25–44 years
More than 4 out of 10 (49.6%) smokers aged 45–64 years
About 4 out of 10 (47.2%) smokers aged 65 years or older
More than 4 out of 10 (45.5%) high school students who smoke tried to stop in the past 12 months
