What causes COPD?

Smoking accounts for 90% of all COPD cases.2 Cigarettes are the primary culprit — and most COPD patients have smoked a pack of cigarettes a day for 10 years or more. But cigar and pipe smokers are also at risk.3 

Exposure to passive smoke, family susceptibility, or inhaling large amounts of dust at work or at home may also cause COPD.2 

Who has COPD?

Millions of people just like you. Right now, more than 12 million people in the United States are diagnosed with COPD; it is estimated that an additional 12 million people have COPD but don’t even know it.4

Most people are diagnosed with COPD when they are 45 years old or older — but signs and symptoms may have been present for years before diagnosis.3
