The health benefits of stopping smoking start almost immediately:
After...
20 minutes: Blood pressure and pulse return to normal 
8 hours: Nicotine and carbon monoxide levels in the blood are halved, oxygen levels in the blood return to normal 
24 hours: Carbon monoxide is eliminated from the body and the lungs start to clear out the build up of tar 
48 hours: There is no nicotine left in the body. Taste and smell are greatly improved 
72 hours: Breathing becomes easier, bronchial tubes begin to relax, energy levels increase 
2 - 12 weeks: Circulation improves, making walking and running a lot easier 
3 - 9 months: Coughs, wheezing and breathing problems improve as the lungs have room for up to 10% more oxygen 
1 year: Risk of heart attack is halved 
10 years: Risk of lung cancer is halved 
10 years: Risk of heart attack is at the same level as non-smokers 
Medium to long-term: Risk of developing lung cancer, other cancers, heart attack, stroke and chronic lung disease is reduced - the sooner you stop, the sooner your risk starts going down 
Medium to long-term: Stopping smoking at any age increases your life expectancy, provided that you stop before the onset of serious disease. Even if you have developed a disease, you can benefit from stopping as your body will be under less strain and be able to fight it more easily 
Medium to long-term: A smoker who has suffered from a heart attack can halve the risk of a second heart attack by stopping smoking 
Medium to long-term: Ten years after stopping smoking an ex-smoker's risk of lung cancer is reduced by 30 - 50% compared with that of a continuing smoker 
Medium to long-term: Smokers who stop before the age of 35 have a life expectancy not significantly different from that of a non-smoker 
Medium to long-term: Smokers who stop between 65 and 74 years of age have a better life expectancy beyond 75 than those who continue to smoke 
For life:
