Popcorn Lung

Bronchiolitis obliterans is a condition better known as Popcorn lung, often attributed to the inhalation of concentrated diacetyl over prolonged periods of time. This condition has never been attributed to e-cigarettes, e-liquid use, or even smoking (which exposes the user to hundreds of times more diacetyl then vaping).

A 2014 publication found that diacetyl was present in samples of many sweet-flavored e-liquids, though at levels 100 times lower than that of traditional tobacco smoke. According to that research, diacetyl is approved for food use, but is associated with respiratory disease when inhaled. Although diacetyl was initially linked to a condition known as popcorn lung (formally bronchiolitis obliterans) among flavored popcorn factory workers, the condition is incredibly rare and likely only occurs with prolonged exposure to pure diacetyl in the air with little or no protection. Despite levels of diacetyl being much higher in traditional cigarettes than it is in e-liquids, bronchiolitis obliterans has never been linked to traditional smoking, yet mass media used the trace-detectable presence of the common flavoring additive in e-liquids to spread the rumour that it was causing popcorn lung.

Currently located in Sydney, Australia, I have been vaping since 2009 and became active in the e-cigarette industry in late 2015. Since then I’ve had the pleasure of visiting over 700 shops in 6 countries.
