Smokers, on average, die 11-12 years earlier than nonsmokers. Smoking is responsible for most lung cancer, COPD, and other lung diseases. Smoking is also a strong risk factor for heart disease and stroke. We also have learned that a person’s chance of developing diabetes is higher by 30-40%. A person with diabetes who smokes is more likely to have trouble controlling their blood sugars and to have complications. Many cancers other than lung cancer are also caused by smoking. Smoking is also a known risk factor for pregnancy complications and impotence.
