  • This chart illustrates the range of risks facing smokers and the greater likelihood of death arising from a smoking related disease.
  • This is from the 40 year follow up of a cohort of British doctors. It illustrates an average loss of life of about 7.5 years and shows that any given age survival rates for smokers are considerably lower. The use of doctors eliminates any social class or income bias.
  • This outlines the type of benefits to be expected. With lung cancer the risk accumulates during a smoking career but does not diminish on cessation, it just stops increasing. Unless the heart has been irreversibly damaged by actual CHD, the heart disease risk gradually subsides to that of a non-smoker over about 10 years. All of us lose lung function as we age – quitting smoking returns the decline in lung function non-smokers.
  • These charts show the impact of quitting smoking on total mortality – the massage is that there are benefits at any age, but these are greater the earlier cessation takes place.
  • These are some other benefits found in the literature.
  • Studies have found a variety of improvements following smoking cessation.
