The Centers for Disease Control and Prevention (CDC) named the outbreak “E-cigarette, or Vaping, Product Use-Associated Lung Injury,” or EVALI. That name embedded e-cigarettes and vaping into the medical language of the outbreak, even as clinical, laboratory, and epidemiological evidence increasingly pointed to vitamin E acetate in illicit, unregulated THC cartridges, not standard nicotine e-cigarettes.
The Centers for Disease Control and Prevention (CDC) named the outbreak “E-cigarette, or Vaping, Product Use-Associated Lung Injury,” or EVALI. That name embedded e-cigarettes and vaping into the medical language of the outbreak, even as clinical, laboratory, and epidemiological evidence increasingly pointed to vitamin E acetate in illicit, unregulated THC cartridges, not standard nicotine e-cigarettes.
This page documents efforts to get the CDC to correct that name, the consequences of leaving it unchanged, the scientific evidence identifying the source of the outbreak, and the people who tried to correct the record in real time.


The harm from the name “EVALI” did not end when the outbreak ended. By conflating nicotine vapor products with illicit THC cartridges, public health messaging distorted risk perceptions, contributed to widespread misunderstanding, and left many people believing that regulated nicotine vaping caused the injuries. That confusion affected many people. People who had switched from combustible tobacco to nicotine vaping went back to smoking. Some people who smoked tobacco became leery of switching. People using unregulated THC carts may not have recognized quickly enough that the warnings applied to the products they were using. With better messaging, some of the illnesses and deaths might have been averted.

This page brings together journal articles, formal policy critiques, media analysis, public health statements, and consumer-led documentation to show how one imprecise name became a lasting public health communication failure.
