据美国疾病控制与预防中心称，去年，超过7万名美国人因芬太尼用药过量死亡。这一死亡人数比美国在越南、伊拉克和阿富汗战争中的军事伤亡总数还要高。 以下是外媒报道。
双语文本
The US Drug Enforcement Administration says that less fentanyl is present in the nation's illicitpill supply and that is helping drive down overdose deaths in the United States. But experts say that there are limitations to this claim and that many other factors are probably playing a role.
美国缉毒局表示，美国非法药丸供应中的芬太尼含量减少，这有助于降低因过量服用而死亡的人数。但专家表示，这一说法有局限性，可能还有许多其他因素在起作用。
There were about 16,000 fewer lives lost in the most recent 12-month period, according to estimates from the US Centers for Disease Control and Prevention--and the vast majority ofthe decrease was in deaths involving fentanyl and other syntheticopioids.
据美国疾控和预防中心估计，最近12个月内死亡人数减少了约16000人，其中绝大多数人死因是芬太尼和其他合成阿片类药物。
Experts say there are some other critical gaps in the DEA analysis that weaken the potential link between the amount of fentanyl present in the drug supply and the drop in overdose deaths. For example, the DEA tested pills, but experts say illicit fentanyl is more commonly found and used in powder form.
专家表示，缉毒局的分析中还存在一些其他关键漏洞，削弱了药物供应中存在的芬太尼数量与过量服用死亡人数下降之间的潜在联系。例如，缉毒局测试了药丸，但专家表示，非法芬太尼更常见的形式是粉末。
The measurement that the DEA uses to define a deadly dose of fentanyl--2 milligrams--is also subjective. Individual responses to fentanyl can vary based on the person's tolerance to the drug, as well as physical and genetic characteristics.
缉毒局用来定义芬太尼致命剂量（2毫克）的测量方法也是主观的。个体对芬太尼的反应因个人对药物的耐受性以及身体和遗传特征而异。
