Vitamin E acetate has been identified as a chemical of concern among people with e-cigarette, or vaping, product use-associated lung injury.
Laboratory data show that vitamin E acetate, an additive in THC-containing products, is closely associated with lung injury.
A recent study analyzed samples from 51 EVALI cases from 16 states and a comparison group of samples from 99 healthy people for vitamin E acetate, plant oils, medium-chain triglyceride (MCT) oil, coconut oil, petroleum distillates, and diluent terpenes.
Vitamin E acetate was identified in bronchoalveolar lavage (BAL) fluid samples (fluid samples collected from the lungs) from 48 of the 51 EVALI patients, but not in the BAL fluid from the healthy comparison group.
No other toxicants were found in BAL fluid from either group, except for coconut oil and limonene (1 EVALI patient each).
