Benefits of quitting

Almost everyone knows that smoking is bad for you but do you know all the benefits of quitting? For the vast majority of smokers, quitting smoking is the best single thing they can do to improve the length and quality of their lives. Persons who quit smoking immediately begin to reduce their chances of developing heart disease, cancer, breathing problems, infections, or being in an accident.

Former smokers also live longer than those who continue to smoke. For example, those who quit before age 50 have only half the chance of dying in the next 15 years compared with those who continue to smoke.

Women who stop smoking before pregnancy or early in their pregnancy reduce their chance of having a low birth weight baby. Quitting can also reduce the chance of stillbirth, early infant death, and improve the health of the woman.

The health benefits of quitting occur for all types of smokers, men and women, young and old. Even those who have developed smoking related problems like heart disease can benefit. For example, compared to continuing smokers, people who quit smoking after having a heart attack reduce their chances of having another heart attack by 50 per cent. They also reduce their risk of dying prematurely by 50 per cent.

What are the other benefits of quitting?

Although reducing your chances of premature death and illness is important, they aren't the only benefits of quitting smoking.
