Vaping has become a popular alternative to traditional smoking, with many people believing that it is a safer option. However, there is growing concern about the potential health risks associated with vaping, particularly when it comes to lung health. One specific concern is the development of a condition known as “popcorn lung,” which has been linked to a flavoring chemical used in some e-cigarette products.
Key Takeaways:
- “Popcorn lung” refers to bronchiolitis obliterans, a serious and irreversible lung disease initially discovered among workers in a microwave popcorn factory exposed to diacetyl.
- E-cigarette companies add diacetyl to enhance flavors such as vanilla, maple, and coconut, which raises concerns about the potential risk to the respiratory health of users.
- The presence of harmful chemicals like diacetyl, 2,3 pentanedione, and acetoin in e-cigarettes can lead to bronchiolitis obliterans or “popcorn lung,” inflammation, lung damage, and other serious respiratory conditions.
- The FDA needs to take immediate action to regulate e-cigarettes, ensure the removal of harmful chemicals, and protect public health.
What Is Popcorn Lung and Its Connection to Vaping?
The term “popcorn lung” refers to bronchiolitis obliterans, a serious and irreversible lung disease that was initially discovered among workers in a microwave popcorn factory over a decade ago. These workers were exposed to diacetyl, a chemical used to give foods like popcorn, caramel, and dairy products a buttery flavor. The inhalation of diacetyl caused scarring of the tiny air sacs in the lungs, leading to the thickening and narrowing of the airways.
While popcorn manufacturers quickly removed diacetyl from their products to protect their workers, the chemical is still being found in many e-cigarette flavors. E-cigarette companies add diacetyl to “e-juice” liquids to enhance flavors such as vanilla, maple, and coconut. Shockingly, a study conducted by researchers at Harvard found that 39 out of 51 e-cigarette brands tested contained diacetyl. Furthermore, the study identified two other harmful chemicals, 2,3 pentanedione and acetoin, in a significant number of the tested flavors.
The presence of these chemicals in e-cigarettes raises concerns about the potential risk to users’ respiratory health. Inhalation of diacetyl, 2,3 pentanedione, and acetoin can lead to bronchiolitis obliterans, or “popcorn lung,” which manifests as symptoms such as coughing, wheezing, and shortness of breath, similar to the symptoms of chronic obstructive pulmonary disease (COPD).
The fact that these harmful chemicals are found in e-cigarettes highlights a pressing public health issue, especially considering the popularity of these devices among youth. Unfortunately, the Food and Drug Administration (FDA) has delayed the requirement for e-cigarette companies to submit their products and ingredients for review until 2022. As a result, these potentially harmful products remain on the market, putting users at risk.
It is crucial that the FDA takes swift action to protect public health by requiring the removal of diacetyl and other harmful chemicals from e-cigarettes. The American Lung Association has filed a lawsuit against the FDA to challenge the delay in enforcing these provisions.

While there is ongoing research into the specific health effects of vaping, it is important to note that the chemicals found in e-cigarette vapor have the potential to cause harm to the respiratory system. Some studies have highlighted the harmful effects of vaping on the lungs, indicating that certain substances in e-liquid can lead to inflammation and damage to lung tissue.
One of the substances of concern is vitamin E, which is commonly used as a thickening and delivery agent in e-liquids. When inhaled, vitamin E can irritate the lungs and has been found in the lungs of individuals with severe vaping-related damage. Other potentially harmful substances found in e-liquid or produced when heated include diacetyl, which is known to damage small passageways in the lungs, formaldehyde, which is toxic and can cause lung and heart disease, and acrolein, which is primarily used as a weed killer but can also damage the lungs.
In addition to concerns about developing popcorn lung, other lung diseases have been associated with vaping. Lipoid pneumonia, for example, can occur when oily substances from e-liquid are inhaled and trigger an inflammatory response in the lungs. Symptoms of lipoid pneumonia include chronic cough, shortness of breath, and coughing up blood or blood-tinged mucus. Treatment for lipoid pneumonia is supportive care, where the lungs heal on their own, but identifying the cause (i.e., vaping) and eliminating it is essential.
Moreover, there have been reports of collapsed lungs in individuals who vape. The act of vaping can increase the risk of primary spontaneous pneumothorax, where a hole develops in the lung and causes air to escape. This can occur due to the rupture of air blisters on the top of the lungs, a risk that is heightened by smoking or vaping. Treating a collapsed lung may involve oxygen treatment and rest, but more severe cases may require a chest tube or surgery.
It is important to note that the potential risk of developing lung cancer from vaping is still unknown, as vaping products have not been around long enough for conclusive studies to be conducted. However, given that vaping introduces a range of chemicals into the lungs and tobacco smoking is known to increase the risk of cancer, it is prudent to be cautious about the potential long-term effects of vaping on lung health.
It is worth mentioning that secondhand vapor from e-cigarettes is not harmless. Contrary to popular belief, the exhaled vapor contains nicotine, ultrafine particles, diacetyl, and benzene, among other substances. While the impact on the lungs may be different than when actively vaping, it is best to avoid exposure to secondhand vapor when possible.

Conclusion
In conclusion, vaping has the potential to cause “popcorn lung” and other respiratory issues due to the presence of harmful chemicals in e-cigarettes. The inhalation of diacetyl, as well as other substances found in e-liquids or produced when heated, can lead to inflammation, lung damage, and the development of serious lung conditions. The FDA needs to take immediate action to regulate these products and ensure the removal of harmful chemicals. Additionally, individuals who vape should be aware of the potential risks to their lung health and consider alternative methods for nicotine or substance delivery.
The fact that e-cigarettes remain unregulated by the FDA is an alarming concern, especially given the popularity of these devices among youth. The delay in enforcing these provisions has resulted in the continued availability of potentially harmful products in the market, putting users at risk. The American Lung Association has filed a lawsuit against the FDA to challenge this delay and ensure that these products are held to the same safety standards as other tobacco products.
Furthermore, the long-term effects of vaping on lung cancer are still unknown, and caution should be exercised given the introduction of a range of chemicals into the lungs. It is time for e-cigarette companies to be held responsible for the potential harm their products can cause to respiratory health.
It is also worth noting that secondhand vapor from e-cigarettes is not harmless, and individuals should avoid exposure to it when possible to reduce the potential risk to their lung health.
Overall, it is essential to prioritize respiratory health and understand the potential risks associated with vaping. Consider alternative methods for nicotine or substance delivery, and demand that e-cigarette companies take responsibility for their products. Only then can we work towards a future where respiratory health is not compromised for the sake of convenience.
