The vaping-related lung disease outbreak has peaked and may be coming to an end. Vitamin E acetate in THC products seems to blame.
The U.S. Centers for Disease Control announced Friday with new confidence that vitamin E acetate seems to be largely to blame for the vaping-related lung illness outbreak that swept the country—at the same time it announced the outbreak seems to be approaching its end.
Building upon prior findings, CDC researchers published a report about vitamin E acetate in the New England Journal of Medicine Friday. Researchers tested lung fluid samples from 51 patients with EVALI from 16 states, as well as from a control group of 99 healthy subjects, some of whom smoked or vaped. They found vitamin E acetate in 48 of the 51 samples from EVALI patients, and in none of the healthy control samples.
It’s not exactly clear how vitamin E acetate could cause lung issues, but Schuchat said there are two leading theories. One is that the oily substance disrupts the lining of the lungs, interfering with their ability to expand. The other is that a byproduct produced by vitamin E acetate during the vaping process could cause a chemical injury to the lungs.
