| ===2020: [https://www.nejm.org/doi/full/10.1056/nejmoa1916433 Vitamin E Acetate in Bronchoalveolar-Lavage Fluid Associated with EVALI]===
| |
| The FDA detected no vitamin E acetate in 197 case-associated nicotine products analyzed to date. The viscosity of vitamin E acetate makes it undesirable as an additive to nicotine solutions.
| |
| Data that have been reported to date indicate that vitamin E acetate in the supply of THC-containing products and use among patients with EVALI aligns with the timing of the 2019 EVALI outbreak. In Minnesota, 10 of 10 products seized by law enforcement during 2018, before the EVALI outbreak, did not contain vitamin E acetate, whereas 20 of 20 THC-containing products seized by law enforcement during September 2019, at the peak of the outbreak, contained vitamin E acetate.
| |
| Pure THC oil has a viscosity like that of vitamin E acetate. Cutting THC oil with vitamin E acetate has been reported to be common in the illicit market.
