The authors refer to an outbreak of 53 cases of e-cigarette and vaping–related lung injury, in which 84% of the cases admitted to the use of tetrahydrocannabinol products. The remaining 16% may have concealed the use of an illegal product, or not known what they were using. In those cases of e-cigarette and vaping–related lung injury where bronchoalveolar lavage was performed, 100% of the specimens were positive for vitamin E acetate, a dangerous contaminant in tetrahydrocannabinol oil. This outbreak is troubling but it is unrelated to the use of legal nicotine-based vaping products. | The authors refer to an outbreak of 53 cases of e-cigarette and vaping–related lung injury, in which 84% of the cases admitted to the use of tetrahydrocannabinol products.

As of December 12, 2019, the Wadsworth Center has analyzed 206 vaporizer fluids from 61 NYS EVALI cases. Of these, 147 contained THC, and 59 contained nicotine. Of the 147 THC-containing fluids, 101 (69%) contained VEA. In the nicotine-containing products we analyzed, we detected no unusual compounds that appeared to be of concern. | As of December 12, 2019, the Wadsworth Center has analyzed 206 vaporizer fluids from 61 NYS EVALI cases.

There is additional evidence of a strong association of VEA with EVALI. In the initial analyses of bronchoalveolar lavage fluids from EVALI patients, 28 of 28 fluids contained vitamin E acetate. | There is additional evidence of a strong association of VEA with EVALI.
