Vaping and the Risk of “Popcorn Lung” Among Teens

Health experts are sounding the alarm on a rare but serious lung disease called “popcorn lung,” scientifically known as bronchiolitis obliterans, which may be linked to vaping—especially among teens. This irreversible condition causes inflammation and scarring in the small airways of the lungs, leading to chronic coughing, wheezing, and difficulty breathing.

The nickname “popcorn lung” originated from microwave popcorn factory workers who were exposed to diacetyl, a chemical used for buttery flavoring. Alarmingly, diacetyl is still found in some flavored vape liquids. When heated and inhaled, it becomes toxic and may contribute to this debilitating disease.

Vaping liquids often contain a mix of harmful substances, including diacetyl, acetaldehyde, and formaldehyde. With over 180 flavoring agents—many untested for safety when inhaled—teens are unknowingly inhaling chemicals that bypass natural defenses and go straight to vital organs.

Symptoms may develop slowly, and while there is no cure, treatments like steroids, inhalers, and oxygen therapy can help manage the condition. In severe cases, a lung transplant may be necessary.

Doctors urge early diagnosis and, more importantly, prevention. Avoiding vaping, especially flavored varieties marketed toward youth, is key to protecting long-term lung health.

Support groups and education are vital for families coping with this hidden danger.
