Health benefits of stopping smoking

The benefits from stopping smoking begin straightaway. The following are examples of the dangers that can be avoided or reduced by quitting smoking.

You reduce your risk of getting serious disease no matter what age you give up. However, the sooner you stop, the greater the reduction in your risk. In fact, researchers have found that if you stop smoking before the age of 50 your risk of dying prematurely is virtually reduced to that of a non-smoker. Even if you give up after the age of 60, your risk of dying at any given age is reduced by about 39% compared to a person who carries on smoking.

If you stop smoking you:

  • If you have smoked since being a teenager or young adult:

    • If you stop smoking before the age of about 35, your life expectancy is only slightly less than it is for people who have never smoked.

    • If you stop smoking before the age of 50, you decrease the risk of dying from smoking-related diseases by 50%.

  • It is never too late to stop smoking to gain health benefits. Even if you already have COPD or heart disease, your outlook (prognosis) is much improved if you stop smoking.
