E-cigarettes, commonly referred to as vapes, have surged in popularity as an alternative to traditional smoking. Many users believe these devices are a safer option, given the lack of tar and combustion, but concerns remain, especially regarding their association with “Popcorn Lung” or bronchiolitis obliterans. This term originated from an unusual outbreak among popcorn factory workers who were exposed to diacetyl, a chemical used to provide a buttery flavor in foods.
What is Popcorn Lung?
Bronchiolitis obliterans, colloquially known as Popcorn Lung, is a rare condition damaging the lungs’ smallest airways, leading to coughing, wheezing, and shortness of breath. The disease name became popular following the discovery that workers inhaling diacetyl-rich vapors developed respiratory problems. Though this chemical flavoring agent was removed from commercial popcorn production, concern arises due to its presence in some e-cigarette liquids.
E-Cigarettes and Diacetyl: The Connection

Research indicates that certain e-liquids contain diacetyl and other potentially harmful chemicals, albeit typically at lower concentrations than found in industrial settings. The inhalation of diacetyl in vapor form poses a risk, although the exact health implications remain a subject of ongoing study. Given the widespread use of e-cigarettes, understanding which brands or flavors may contain diacetyl is crucial for consumer safety.

Potential Health Risks Beyond Popcorn Lung
E-cigarette Usage: A Balanced View
While e-cigarettes might indeed reduce exposure to many harmful substances associated with traditional smoking, they are not without risk. Smokers seeking safer alternatives should approach vaping with caution, ensuring they select products with transparency regarding ingredient lists and preferably those certified as diacetyl-free. It’s important for consumers to stay informed through reliable research and thorough understanding of e-cigarette components.
The Smokers’ Dilemma: Weighing Risks
Users weighing the decision to switch from cigarettes to e-cigarettes must consider the balance between potential benefits and risks. While reducing tar and combustion exposure is beneficial, monitoring and evaluating the extent of exposure to other volatile compounds present in e-liquids can shape healthier usage habits.
