What Is Popcorn Lung
Popcorn lung is a nickname for bronchiolitis obliterans, a condition that damages the smallest airways in the lungs. It causes scarring that can lead to coughing, wheezing, and shortness of breath. The name comes from early cases tied to inhaling diacetyl, a butter-flavoring chemical used in some microwave popcorn factories.
Is Popcorn Lung Caused by Vaping
Vaping does not directly cause popcorn lung in most documented cases. However, some e-liquids have contained diacetyl or similar flavoring chemicals. Inhaling these substances over time may irritate airways. Major health agencies note that vaping exposes users to potentially harmful chemicals, though direct links to popcorn lung in vapers remain rare and under study.

Key Facts and Practical Guidance
Popcorn lung is diagnosed through lung function tests and imaging, not by symptoms alone. Common causes include workplace exposure to flavoring fumes, respiratory infections, and certain autoimmune conditions. If you vape and notice persistent cough or breathing trouble, seek medical evaluation. Reducing or stopping use of flavored vaping products can lower exposure to additives like diacetyl.
