E-cigarettes linked to incurable ‘Popcorn Lung’ disease.

According to researchers at Harvard T.H. Chan School of Public Health, the harmful ingredient is the flavoring, as more than three out of four e-cigarettes and refill liquids they tested contained Diacetyl, a chemical linked to the disease, properly called bronchiolitis obliterans.

“Recognition of the hazards associated with inhaling flavoring chemicals started with ‘Popcorn Lung’ over a decade ago. However, diacetyl and other related flavoring chemicals are used in many other flavors beyond butter-flavored popcorn, including fruit flavors, alcohol flavors, and, we learned in our study, candy flavored e-cigarettes,” said lead author Joseph Allen, assistant professor of exposure assessment science, according to a release on the Harvard T.H. Chan School of Public Health website.

The study selected 51 types of flavored e-cigarettes “sold by leading e-cigarette brands and flavors we deemed were appealing to youth.”
