A dire warning has been issued by health professionals after a 17-year-old girl was diagnosed with irreversible “popcorn lung,” a severe respiratory condition linked to vaping—a habit that has become increasingly popular among teenagers.

The teen, whose story has quickly gained traction online, was hospitalized after experiencing months of shortness of breath, chest pain, and fatigue. Despite her young age and otherwise healthy lifestyle, doctors discovered she had developed bronchiolitis obliterans, more commonly known as popcorn lung—an incurable condition that damages the smallest airways in the lungs and causes permanent breathing problems.

Medical experts attribute the illness to chemicals commonly found in flavored vape liquids, particularly diacetyl, a buttery-flavored additive that has been banned in some countries but still appears in various e-liquids on the market.

“This isn’t just a scare tactic,” said Dr. Elaine Turner, a pulmonologist who treated the teen. “We’re seeing irreversible lung damage in kids who are still in high school. Vaping is not a harmless alternative—it’s a fast track to chronic illness.”

Popcorn lung, originally linked to workers in microwave popcorn factories exposed to diacetyl, is now resurfacing in a new demographic: young vape users. The condition inflames and scars the lungs’ airways, leading to symptoms that mimic severe asthma or COPD. There is no known cure, only treatments that may ease discomfort.

The girl, who is now undergoing ongoing respiratory therapy, shared her story to warn others about the hidden dangers of vaping. A photo of her in a hospital gown, using a nebulizer, has since gone viral—sparking conversations across schools, parent groups, and health forums.

“I thought vaping was safer than smoking,” she reportedly told hospital staff. “I never thought it could take away my ability to breathe.”

Health officials are urging parents, schools, and lawmakers to take action through education and tighter regulation. Meanwhile, doctors are advising teens to rethink the trend before it results in irreversible damage.
