This is how much – and how quickly – you’ll reap the benefits of quitting.

Smoking damages every organ in the body. These are the major advantages of giving up smoking:

  • After 20 minutes:

    Your blood pressure and pulse are back to normal and your circulation has improved.
  • After 8 hours:

    Your cells are receiving a normal supply of oxygen again, and your risk of a heart attack is decreasing.
  • After 24 hours:

    Carbon monoxide from the cigarette smoke has been completely eliminated from your body. Your lungs start to break down the mucus and smoke residues.
  • After 48 hours:

    Your body is now free of nicotine. Your sense of smell and taste is improving.
  • After 72 hours:

    Breathing is easier. Your bronchi are relaxing and you have more energy.
  • After 2–12 weeks:

    Your circulation is improving, and this improves your performance during sports and sex.
  • After 3–9 months:

    Breathing difficulties, shortness of breath and wheezing are becoming much less of a problem. Your lung function is improving.
  • After 5 years:

    Your risk of a heart attack is now only half that of a smoker.
  • After 10 years:

    Your risk of developing lung cancer is now only half that of a person who smokes.
