You will feel the benefits of quitting straight away as your body repairs itself. Depending on the number of cigarettes you smoke, typical benefits of stopping are:

  • After twelve hours almost all of the nicotine is out of your system.
  • After twenty-four hours the level of carbon monoxide in your blood has dropped dramatically. You now have more oxygen in your bloodstream.
  • After five days most nicotine by-products have gone.
  • Within days your sense of taste and smell improves.
  • Within a month your blood pressure returns to its normal level and your immune system begins to show signs of recovery.
  • Within two months your lungs will no longer be producing extra phlegm caused by smoking.
  • After twelve months your increased risk of dying from heart disease is half that of a continuing smoker.
  • Stopping smoking reduces the incidence and progression of lung disease including chronic bronchitis and emphysema.
  • After ten years of stopping your risk of lung cancer is less than half that of a continuing smoker and continues to decline (provided the disease is not already present).
  • After fifteen years your risk of heart attack and stroke is almost the same as that of a person who has never smoked.

Quitting smoking can be one of the most difficult, yet rewarding things a person can do. Most smokers say they would like to quit, and may have tried at least once. Some are successful the first time, but many other people try a number of times before they finally give up for good.
