疾病预防控制中心发现从29个与电子烟有关的肺损伤病例中获取的肺部样本中发现了维生素E醋酸酯。该中心在公告中写道:“这是我们第一次在肺损伤患者的生物样本中检测到一种潜在的化学物质,检测结果提供了维生素E醋酸酯存在于肺损伤主要部位的直接证据”。
In addition to E acetate, the organization also identified THC, the psychoactive property in cannabis, in 82% of lung samples and nicotine in 62% of samples. The CDC says it tested for other chemicals, including plant oils, petroleum distillates, MCT oil, and terpenes, but was not able to detect them.
除了维生素E醋酸酯,该中心还在82%的肺部样本中发现了四氢大麻酚,在62%的样本中发现了尼古丁。四氢大麻酚是大麻中的精神活性物质。疾病预防控制中心称测试了其他化学物质,包括植物油、石油馏出物、中链甘油三酯和萜烯,但没有任何发现。
The Food and Drug Administration has also released preliminary lab results showing a strong presence of vitamin E acetate among nearly 600 lung samples. The administration found that the majority of samples taken from patients in 25 states contained THC. Half of the samples with THC also had vitamin E acetate; another 22% contained a different diluent.
美国食品药物管理局也公布了初步实验结果,发现在近600个肺部样本中大量存在维生素E醋酸酯。管理局发现收集到的25个州的病人样本中大部分都有四氢大麻酚。含有四氢大麻酚的样本中一半含有维生素E醋酸酯,另外22%含有另外一种稀释剂。
