Weed vapes may not be safe from vaping-linked health problems
大麻蒸汽烟或导致健康问题
The victim tally continues to rise for the vaping-linked now known as EVALI, an acronym that stands for e-cigarette or vaping product use-associated lung injury, and which appeared to be linked mainly to nicotine-delivering vape products. Unfortunately, weed vapers who thought they were safe from vaping-related health issues may not be safe either, as a new study found that marijuana vapes may harbor different harmful chemicals.
电子烟或蒸汽烟相关的肺损伤（EVALI）病例持续增加，这似乎主要与传递尼古丁的电子烟产品相关。不幸的是，大麻蒸汽烟民原以为自己可免受使用蒸汽产品相关的健康疾病，但事实却并非如此一项新研究发现，大麻蒸汽烟可能含有几种不同的有害化学物。
As reported by the Centers for Disease Control and Prevention (CDC) last week, a total of 2,291 cases of EVALI from around the country were reported as of December 3. Forty-eight deaths were confirmed in 25 states and the District of Columbia. In the beginning of September, numbers hovered around 450 people being hospitalized, and five deaths. As scientists continue to investigate the outbreak and illness, they are faced with a lot of unknowns, including a specific product and cause. The CDC states it appears that vitamin E acetate is associated with EVALI, however, evidence is not yet sufficient to rule out contribution of other chemicals of concern.
美疾控中心上周表示，截至12月3日，全美共报道2291例EVALI病例。在美国25个州以及哥伦比亚特区，共有48人因此离世。9月初，大约450人住院，5人死亡。科学家在进一步调查病情爆发的原因时面临着许多未知数，包括特定的产品和病因。美疾控中心指出维生素E醋酸盐似乎与EVALI有关，但我们的证据还不足以排除其它化学物质是否在其间产生了作用。
A recent study published in the September issue of academic journal ACS Omega, is raising questions about what happens when additives are put into cannabis vaping products. The study seeks to bring a greater understanding about product safety when cannabis is inhaled using nontraditional methods like vaping.
9月份发表在ACS Omega学术期刊上的一篇研究引发了大家的思考：将添加剂放入大麻蒸汽产品中会发生什么。这项研究旨在让人们进一步了解使用蒸汽烟等非传统方法吸大麻时是否安全。
What's inhaled is actually different than what's listed in the ingredients, Portland State University Chemistry Professor Rob Strongin, who led the research team for the study, said in a media statement.
该研究团队的负责人、波特兰州立大学的化学教授罗布斯特金（Rob Strongin）在一份媒体声明中表示：实际上，烟民吸入的物质与成分中列出的物质存在差异。
Researchers found that in these chemical reactions, more toxins emerged from terpenes than from THC. Specifically, they found a nearly fivefold increase in the chemical isoprene, which was released from THC with 10 percent more terpenes compared to THC alone. Inhaling isoprene caused tumors in mice and rats.
研究人员发现，在这些化学反应中，萜烯产生的毒素高于四氢大麻酚。具体而言，他们发现四氢大麻酚释放的异戊二烯这一化学物质的含量增加了近五倍，且与四氢大麻酚相比，萜烯的含量增加了10%。小鼠和大鼠吸入异戊二烯会引发肿瘤。
Several identified components are International Agency for Research on Cancer-classified carcinogens, and exposure to these may place a burden on the health of people that use vaping to consume cannabis, the researchers stated.
研究人员表示：我们确定了其含有国际癌症研究机构致癌物质分类中的几种成分，接触这些成分可能会给大麻蒸汽烟民的健康带来负担。
