The best thing smokers can do for their health is to quit smoking. It doesn’t matter whether you are male or female, young or old or how long you have been smoking, quitting will improve your health. Even if you already have a smoking-related problem like heart or lung disease, you still benefit from quitting.

Health benefits of quitting

  • If you quit before age 35 your life expectancy is similar to someone who has never smoked.
  • If you quit before age 50 you halve your risk of dying before you turn 65.
  • Quitting at any age increases life expectancy and improves quality of life.
  • Quitting smoking reduces your risk of:
    • cancer of the lung, throat, mouth, lips, gums, kidney and bladder
