大麻蒸汽煙或導致健康問題
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.
“電子煙或蒸汽煙相關的肺損傷”（EVALI）病例持續增加，這似乎主要與傳遞尼古丁的電子煙產品相關。不幸的是，大麻蒸汽菸民原以爲自己可免受使用蒸汽產品相關的健康疾病，但事實卻並非如此——一項新研究發現，大麻蒸汽煙可能含有幾種不同的有害化學物。
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."
美疾控中心上週表示，截至12月3日，全美共報道2291例EVALI病例。在美國25個州以及哥倫比亞特區，共有48人因此離世。9月初，大約450人住院，5人死亡。科學家在進一步調查病情爆發的原因時面臨着許多未知數，包括特定的產品和病因。美疾控中心指出“維生素E醋酸鹽似乎與EVALI有關，”但“我們的證據還不足以排除其它化學物質是否在其間產生了作用。”
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月份發表在ACS Omega學術期刊上的一篇研究引發了大家的思考：將添加劑放入大麻蒸汽產品中會發生什麼。這項研究旨在讓人們進一步瞭解使用蒸汽煙等非傳統方法吸大麻時是否安全。
"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.
該研究團隊的負責人、波特蘭州立大學的化學教授羅布·斯特金（Rob Strongin）在一份媒體聲明中表示：“實際上，菸民吸入的物質與成分中列出的物質存在差異。”
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.
研究人員發現，在這些化學反應中，萜烯產生的毒素高於四氫大麻酚。具體而言，他們發現四氫大麻酚釋放的異戊二烯這一化學物質的含量增加了近五倍，且與四氫大麻酚相比，萜烯的含量增加了10%。小鼠和大鼠吸入異戊二烯會引發腫瘤。
"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.
研究人員表示：“我們確定了其含有國際癌症研究機構致癌物質分類中的幾種成分，接觸這些成分可能會給大麻蒸汽菸民的健康帶來負擔。”
