Tobacco use is responsible for about one in five deaths annually in the United States.
Smoking can damage virtually all systems of your body and can cause:
- Acute lung disease, such as pneumonia
- Chronic lung disease, such as emphysema and chronic obstructive pulmonary disease (COPD)
Other conditions related to smoking include:
- Periodontitis or gum disease
- Peptic ulcer disease
Second-hand smoke can cause premature death and disease in both children and adult non-smokers.
Children exposed to second-hand smoke are at an increased risk for sudden infant death syndrome (SIDS) and may also develop:
- Acute respiratory infections
- Ear problems
- More severe asthma
- Respiratory symptoms and slowed lung growth if parents smoke
Adults exposed to second-hand smoke are at increased risk for coronary heart disease and lung cancer. Second-hand smoke may also have an immediate negative effect on your cardiovascular system.
