Health benefits of Quitting

• People who stop smoking greatly reduce their risk of dying prematurely. Benefits are greater for people who stop at earlier ages, but cessation is beneficial at all ages.

• Smoking cessation lowers the risk for lung and other types of cancer. The risk for developing cancer declines with the number of years of smoking cessation.

• Risk for coronary heart disease, stroke, and peripheral vascular disease is reduced after smoking cessation. Coronary heart disease risk is substantially reduced within 1 to 2 years of cessation.

Quitting (cont.)

• Cessation reduces respiratory symptoms, such as coughing, wheezing, and shortness of breath. The rate of decline in lung function is slower among persons who quit smoking.

• Women who stop smoking before or during pregnancy reduce their risk for adverse reproductive outcomes such as infertility or having a low-birth-weight baby.
