2. COPD Does Not Affect Only Smokers
While is true that as many as nine out of 10 people diagnosed with COPD are past or current smokers, COPD can also develop in people who don’t smoke. Other risk factors for this condition include exposure to toxic chemicals such as silica and cadmium, or working in places with excessive dust, industrial smoke or other air pollutants. If you work in such environment, or if you are a miner, furnace worker or grain farmer, you should see your doctor regularly to assess the function of your lungs.
