Popcorn Lung and Diacetyl

There are many weird and wonderful myths which, for one reason or another, the vaping community just cannot seem to shake. The most glaring of these myths and mistruths is the idea that vaping causes an unpleasant medical issue known as popcorn lung, which is in fact a moniker given to bronchiolitis obliterans: a condition which damages the small airways in the lungs and causes coughing and shortness of breath.  

What is Popcorn Lung?

The reason that this condition came to be known as popcorn lung is likely due to reports of popcorfactory workers who experienced an ailment known as popcorn lung when exposed to high levels of diacetyl. Because some e-liquids contain diacetyl, the assumption was made that vaping e-liquids could also lead to the affliction. However, very few e-liquids actually use diacetyl and those that do contain far too small of an amount to cause any harm. It should also be noted that traditional tobacco cigarettes also contain diacetyl in significantly higher amounts than what is present in e-liquids.   

What is Diacetyl?

Diacetyl is a by-product of the fermentation process used during the production of dairy products and is generally used in food and drink to give a sweet, buttery flavour. While safe for human consumption, the issue with diacetyl appears to lie with inhaling the substance in extremely large quantities as is experienced when working in a factory which uses diacetyl on an industrial scale.  

In analysis carried out by CDC (Centre for Disease Control & Prevention), it is explained that “the Food and Drug Administration regulates flavourings based on the safety of the amounts consumed, not the safety of prolonged worker inhalation of high concentrations. The statement goes on to explain that CDC has no evidence to suggest risk for consumers in the preparation and consumption of microwave popcorn.”  

Diacetyl is only found in e-liquid when certain flavourings are used and is not present in the vegetable glycerinepropylene glycol or nicotine base ingredientsTraces of diacetyl are generally only found in custard and pastry flavours to give that warm and comforting buttery exhale, but even so the levels of diacetyl in these liquids is far too minute to have any negative impact on the lungs.
