Smoking has an overwhelming amount of scientific evidence against it. It is just impossible for a smoker to honestly believe that smoking is good for the quality and length of their life. For starters, let's discuss some staggering reasons from the US Surgeon General's Report:

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) regain normal function in the lungs, increasing the ability to 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 smoker's.

5 years after quitting: Your stroke risk is reduced to that of a nonsmoker 5 to 15 years after quitting.

10 years after quitting: The lung cancer death rate is about half that of a continuing smoker's. The risk of cancer of the mouth, throat, esophagus, bladder, cervix, and pancreas decrease.

15 years after quitting: The risk of coronary heart disease is that of a non-smoker's.
