美国食品药物管理局在报告中写道：“重要的是，不同的使用模式、据报告患者使用的不同产品或物质以及不同的检测样本可能意味着这些损伤是由多种原因造成的。”

　　电子烟和传统香烟哪个危害大？疾病预防控制中心发现从39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。”

　　电子烟和传统香烟哪个危害大？实验室的研究结果可能发现这种疾病与大麻电子烟有着更密切的联系。他们也证实了纽约州卫生部九月份首次提出的怀疑，他们怀疑这一疾病与维生素E醋酸酯有关。该机构发现纽约的一部分患者体内维生素E醋酸酯水平较高。

　　虽然这些新的研究结果让我们对电子烟导致的疾病有了一些了解，但调查仍在继续。

　　In addition to E acetate, the organization also identified THC, the psychoactive property incannabis, in 83% of lung samples and nicotine in 63% of samples. The CDC says it tested forother chemicals, including plant oils, petroleum distillates, MCT oil, and terpenes, but was notable to detect them.

　　E acetate is a form of vitamin E that's often used in skincare products, but which has recentlybecome a popular way of cutting cannabis in vaporizer cartridges. Both the CDC and the FDAhad previously warned Americans against using THC vaping products until the source of theillness has been found.

　　Though these new findings provide some insight into the vaping illness, the inveSTIGation willcontinue.

　　Both the Centers for Disease Control and Prevention and the Food and Drug Administrationreleased new findings, reporting that vitamin E acetate appeared in a large portion of lungsamples of people suffering from a vaping-related illness affecting 3,051 people.

　　除了维生素E醋酸酯，该中心还在83%的肺部样本中发现了四氢大麻酚，在63%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。

　　"importantly, the variations of use patterns, products or substances reportedly used and thesamples being tested may mean there are multiple causes of these injuries," the FDA wrote inits report.

　　The CDC found vitamin E acetate in lung samples taken from 39 patients suffering from lunginjury associated with e-cigarettes. "This is the first time that we have detected a potentialchemical of concern in biologic samples from patients with these lung injuries," the CDC wrotein its announcement. "These findings provide direct evidence of vitamin E acetate at theprimary site of injury within the lungs."
