Vaping-related lung injuries are primarily linked to vitamin E acetate in THC-containing products
Vaping-related lung injuries, specifically the 2019 EVALI outbreak, are strongly linked to vitamin E acetate found predominantly in illicit THC-containing vaping products. Multiple studies and reviews confirm its detection in affected patients and its role in causing acute pulmonary damage.
The retrieved papers consistently support the claim that EVALI is heavily linked to vitamin E acetate (VEA), particularly in THC-containing products, though some newer case reports note nicotine-only cases as well. Papers 0, 1, 9, and 10 explicitly tie VEA to EVALI pathophysiology. Therefore, the overall balance verdict is SUPPORTED.

Simulations and kinetic models show that vitamin E acetate decomposes under vaping conditions to produce toxic ketene gas, contributing to EVALI.

The acute impacts of vaping during the major outbreak were characterised by the emergence of EVALI linked to vitamin E acetate exposure.

Literature reviews indicate that a vast majority of EVALI patients tested positive for vitamin E acetate in bronchoalveolar lavage fluid.

Research highlights the role of vitamin E acetate in the pathophysiology of EVALI, where its thermal breakdown and surfactant disruption cause acute respiratory failure.
