The chemicals in cigarette smoke weaken lungs’ defense against infections,
narrow air passages,
cause swelling in air tubes and destroy air sacs all contributing factors for COPD.
Using other tobacco products like e-cigarettes and cigars also increase risk of developing COPD.
- COPD is a lung disease that’s usually caused by smoking, although some people who smoke for years never get the condition,
- while a few get COPD even if they’ve never lit up.
- Most people with COPD have a combination of a cough that just won’t go away, called chronic bronchitis, and lung damage, called emphysema.
