Smoking and COPD (Chronic Obstructive Pulmonary Disorder)

Cigarettes contain many hazardous substances that damage the lung when inhaled, including tar nicotine, carbon monoxide, and cyanide. Long-term exposure to secondhand tobacco smoke and/or repeated respiratory infections also can increase a person's risk for chronic obstructive pulmonary disorder.
