ENDS EVALI VALI THCVALI

Studies, Surveys, Papers, and Case Studies

Sometimes it's necessary to view the PDF version to access the full study.
EVALI / VALI / THCVALI was originally blamed by some experts on the use of nicotine vapor products. It was proven that it was caused by illicit THC (marijuana / cannabis) cartridges, not nicotine products. It appears that most of the cases were caused by Vitamin E, which was used as a cutting and thickening agent to lower manufacturing costs and to make the products appear to be high quality. On this page, we will chronicle the studies and media covering the truth about the cause of this illness that caused several deaths in the United States.

Suggested studies to add to this page

Updated February 20, 2020
Among the case patients for whom laboratory or epidemiologic data were available, 47 of 50 (94%) had detectable tetrahydrocannabinol (THC) or its metabolites in BAL fluid or had reported vaping THC products in the 90 days before the onset of illness.
Vitamin E acetate was associated with EVALI in a convenience sample of 51 patients in 16 states across the United States.
