You may have seen the term “popcorn lung” trending online — but what exactly does it mean?
Popcorn lung is the nickname for bronchiolitis obliterans, a rare and irreversible lung disease. It causes inflammation and scarring in the smallest airways of the lungs (bronchioles), which makes it difficult for air to flow properly.
The name dates back to the early 2000s when several workers at a microwave popcorn factory developed this condition after being exposed to a flavoring chemical called diacetyl — commonly used to create a buttery taste.
How Vaping Became Associated with Popcorn Lung
Vaping and e-cigarettes have often been linked to popcorn lung because some flavored vape liquids once contained diacetyl. According to the Centers for Disease Control and Prevention (CDC), diacetyl can become a toxic inhalant when aerosolized, leading to lung irritation and long-term damage.

While diacetyl is now banned in the UK and EU, it may still appear in illegal or unregulated vape products. The U.S. Food and Drug Administration (FDA) also warns that some e-liquids, particularly those from unauthorized sellers, can contain unsafe additives or flavoring agents.
In simple terms: not every vape causes popcorn lung — but using unregulated or flavored vapes increases the risk.
What Are the Symptoms?
Popcorn lung doesn’t appear overnight. Symptoms often begin a few weeks after exposure to a harmful gas, chemical, or infection.

According to Cleveland Clinic and WebMD, the most common symptoms include:
- Persistent dry cough
- Shortness of breath (especially during activity)
- Wheezing (even without asthma)
- Fatigue or unexplained tiredness
- Occasionally, fever, night sweats, or skin rash
These signs can resemble asthma or bronchitis, which means diagnosis can be tricky. If symptoms persist, it’s important to consult a healthcare professional for proper testing.
Can Popcorn Lung Be Cured?
Unfortunately, there’s no known cure for popcorn lung. Once lung tissue is scarred, the damage is permanent.

Treatments mainly focus on managing symptoms and preventing further damage. These may include:
- Bronchodilators to open airways
- Steroids to reduce inflammation
- Oxygen therapy for breathing support
- In extreme cases, lung transplantation
As Professor Donal O’Shea from RCSI University explains, “Prevention – not treatment – is the best and only defense.”
How to Protect Yourself
Here’s what health experts recommend for keeping your lungs safe:
- Avoid unregulated vapes — Only purchase products that are certified and legally sold.
- Choose non-flavored e-liquids, as these are less likely to contain harmful additives.
- Stay informed — Check resources from WHO and CDC for vaping safety updates.
- Quit smoking and vaping entirely if possible — studies suggest that lung function improves over time after quitting.
If you’re looking for support, many organizations like SmokeFree.gov offer free quitting resources.
The Bigger Picture: What We Still Don’t Know
Researchers are still studying the long-term effects of vaping, especially among young users. Early data from the Office for National Statistics (ONS) in the UK shows that vaping rates among under-25s have increased significantly.
While vaping may be less harmful than traditional smoking, “less harmful” doesn’t mean harmless. Staying cautious, informed, and choosing regulated products is key.
