Causes
The main cause of emphysema is long-term exposure to airborne irritants, including:
- Tobacco smoke
- Marijuana smoke
- Air pollution
- Chemical fumes and dust
Rarely, emphysema is caused by an inherited deficiency of a protein that protects the elastic structures in the lungs. It's called alpha-1-antitrypsin deficiency emphysema.
