Q. Do former smokers still have long-term health risks?
A. Smoking raises your risk of premature death, lung cancer, heart attacks, strokes, respiratory disease, and other health problems. Does your health “reset” after you quit smoking? Research has examined both the benefits of quitting smoking at various ages, and the health risks of former smokers. The main message is that quitting smoking at any time will benefit your health and extend your life, but quitting young is best.
