The Truth About Popcorn Lung: Can Vaping Cause It?

Vaping is an enjoyable hobby that lets you socialize and create a lasting impression every time you do tricks, but many people shy away from trying it because they fear it can cause popcorn lung. This is a condition that is known as bronchiolitis obliterans, a lung disease that makes you cough and causes shortness of breath due to its impact on your bronchioles, alveoli, and surrounding scar tissue that reduces your lung’s ability to pass air. Learn more about the direct relationship between popcorn lung and vaping by reading the details below.

What Causes Popcorn Lung?

Diacetyl is a chemical that directly causes popcorn lung. It is an organic compound that tastes buttery, and it can be found in a wide variety of food and dairy products, including butter, cheese, coffee, milk, yoghurt, beer, wine, and honey.

Do Vapes Contain Diacetyl?

Diacetyl had been detected in some e-liquid flavourings in the previous years, but its levels are at least hundreds of times lower than those found in cigarette smoke. However, these levels are not considered risky, and there is no evidence in vaping that it causes popcorn lungs. At present, this compound is banned as an ingredient in e-liquids and electronic cigarettes in the UK.

In general, you should not be able to find diacetyl in your e-liquid. But with many brands that are not based or manufactured in the UK, it can be challenging to ensure that this compound is not in your vaping products. For your peace of mind, it is best to always do your research, read the ingredients they use, and visit the manufacturers’ websites before buying.

Does Vaping Cause Popcorn Lung?

Currently, while there are detections of the chemical diacetyl in your e-liquid, there is no solid evidence to prove that vaping or the use of e-cigarettes causes popcorn lung. Remember that this same chemical is also found in different food products, which means it’s possible that you consume it every day, and as long as it has low levels, it should be safe.

What Should I Do If I Am Still Worried about Vaping?

  • Equip yourself with the necessary knowledge

As they say, knowledge is power. Research first and check the ingredients of all e-liquid products you intend to buy before making your purchase. If you can’t find the ingredients used on the manufacturer’s website, consider reaching out to them directly and ask for lab reports. This will ease your mind about your purchase and help you make an informed decision when choosing vaping liquids.

  • Buy only e-cigarette products from TPD-compliant retailers

When buying e-liquids, confirm if your retailer complies with the Tobacco Products Directive (TPD) or European Tobacco Products Directive (EUTPD). This is a directive that oversees or limits on the sale and merchandising of tobacco products in Europe.


Have a safe and enjoyable vaping experience by being a responsible customer. One way to do that is by checking the ingredients of your vaping products. Make sure to buy only from reputable vape stores to ensure the quality and safety of your items.
