After Quitting.

Have a look at these health benefits over time:

20 minutes after quitting, your heart rate and blood pressure drop.
12 hours after quitting, the carbon monoxide level in your blood drops to normal.
2 weeks to 3 months after quitting, your circulation improves and your lung function increases.
1 to 9 months after quitting, coughing and shortness of breath decrease; cilia (tiny hair-like structures that move mucus out of the lungs) start to regain normal function, and are better ableto handle mucus, clean the lungs, and reduce the risk of infection.
1 year after quitting, the excess risk of coronary heart disease is half that of a continuing smoker’s.
5 years after quitting, the risk of cancer of the mouth, throat, oesophagus and bladder is halved. Cervical cancer risk falls to that of a non-smoker. Stroke risk can fall to that of a non-smoker after 2-5 years.
10 years after quitting, the risk of dying from lung cancer is about half that of a person who is still smoking. The risk of cancer of the larynx (voice box) and pancreas decreases.
15 years after quitting, the risk of coronary heart disease is that of a non-smoker’s.
