Popcorn Lung Myth: Why Health Sites Still Get It Wrong
The persistent association between vaping and “popcorn lung” highlights how incomplete scientific communication can distort perceptions of health risks.
Although diacetyl, a flavouring chemical linked to occupational lung disease, was previously detected in some e-cigarettes, no confirmed cases of popcorn lung have been attributed to vaping. The chemical has also been prohibited in regulated e-liquids in the UK and EU for years.
Continued references to this risk without appropriate context may discourage smokers from switching to lower-risk alternatives. Accurate public health messaging must distinguish between potential hazards, actual exposure and established evidence.
