芬太尼是一种强效合成阿片类药物，正在推动加拿大和美国的药物死亡人数激增。 Fentanyl, a powerful synthetic opioid, is driving a surge in drug deaths across Canada and the U.S.

芬太尼是一种强效合成阿片类药物，开发于 1959 年，已成为加拿大和美国非法药物死亡的主要原因。 Fentanyl, a highly potent synthetic opioid developed in 1959, has become the primary cause of illicit drug deaths in Canada and the U.S. 它比海洛因强 20 到 40 倍，比吗啡强 100 倍。 It is 20 to 40 times stronger than heroin and 100 times stronger than morphine. 由于其低成本和检测不到的性质，芬太尼具有致命过量的重大风险。 Due to its low cost and undetectable nature, fentanyl poses a significant risk of fatal overdose. 在加拿大，它与 2024 年上半年 79% 的阿片类药物中毒意外死亡有关，自 2016 年以来增加了 39%。 In Canada, it was linked to 79% of accidental opioid toxicity deaths in the first half of 2024, marking a 39% increase since 2016. 去年，美国海关在加拿大边境查获了 19.5 公斤芬太尼，而墨西哥边境查获了 9,570 公斤。 U.S. customs seized 19.5 kg of fentanyl at the Canadian border last year, compared to 9,570 kg at the Mexican border.
