How is smoking related to heart disease?
Smoking is the best risk factor to eliminate for prevention of death related to heart disease; it is responsible for 30-45% of such deaths in the U.S.
What cancers are more likely in smokers?

Describe the effects of smoking on the lung.
Lung cancer and COPD (emphysema, chronic bronchitis, and bronchiectasis) are due to smoking. Emphysema almost always results from smoking; if the patient is very young or has no smoking history, consider alpha1-antitrypsin deficiency. Although the changes of emphysema are irreversible, the risk of death still decreases if the patient stops smoking.
