Popcorn Lung and Vaping: A Hidden Danger for Teens

“Popcorn lung,” or bronchiolitis obliterans, is a serious, irreversible lung disease causing inflammation and scarring in the smallest airways, making breathing difficult. It was first identified in microwave popcorn factory workers exposed to diacetyl, a chemical used for buttery flavoring. Unfortunately, diacetyl is still found in some vape liquids, especially in the US, and becomes toxic when inhaled.

Vaping liquids contain many harmful chemicals like acetaldehyde, formaldehyde, and others, which can damage lungs when inhaled regularly. There are over 180 flavoring chemicals used in vaping, many untested for safety when heated and inhaled. This creates a risky, unpredictable mix that can lead to popcorn lung.
Symptoms include coughing, wheezing, fatigue, and shortness of breath, but they may not appear immediately. There is no cure for popcorn lung; treatments focus on easing symptoms and slowing progression. The best prevention is to avoid exposure to these harmful chemicals by not vaping or smoking.

Flavored vape products attract many young people, with flavors like cotton candy and mango making vaping appealing. However, inhaling these chemicals bypasses the body’s natural defenses and quickly reaches critical organs, increasing health risks.

Early diagnosis and avoiding further exposure are crucial. Treatments may include inhalers, steroids, oxygen therapy, or, in severe cases, lung transplants. Protecting lung health also involves avoiding smoke, pollution, and infections.

Support groups can help patients and families cope with the challenges of living with popcorn lung.
