A combined analytical, theoretical, and experimental study has shown that the vaping of vitamin E acetate has the potential to produce exceptionally toxic ketene gas, which may be a contributing factor to the upsurge in pulmonary injuries associated with using e-cigarette/vaping products. Additionally, the pyrolysis of vitamin E acetate also produces carcinogen alkenes and benzene for which the negative long-term medical effects are well recognized. As temperatures reached in vaping devices can be equivalent to a laboratory pyrolysis apparatus, the potential for unexpected chemistries to take place on individual components within a vape mixture is high. Educational programs to inform of the danger are now required, as public perception has grown that vaping is not harmful.
一项综合分析、理论和实验研究表明，吸食维生素 E 醋酸酯有可能产生毒性极高的乙烯酮气体，这可能是导致与使用电子烟/蒸气产品相关的肺部损伤病例激增的一个因素。此外，维生素 E 醋酸酯的热解还会产生致癌烯烃和苯，其长期的负面影响是众所周知的。由于电子烟设备中的温度可能相当于实验室热解设备，因此在蒸气混合物的个别成分中发生意外化学反应的可能性很高。现在需要开展教育计划，告知其危害，因为公众的看法已经发生变化，认为蒸气产品没有危害。
