每一张纸屑都要检查：正当美国与致命的新毒品疫情搏击之际，《BBC新闻》从吸毒者、毒贩、监狱和戒毒工作人员那里听取了情况。芝加哥最大的监狱、也是美国最大的单一使用监狱是库克县监狱。
Every scrap of paper checked: Police hunting for synthetic drugs in Chicago jail BBC News hears from users, dealers, prison and recovery workers as America battles with a deadly new drug epidemic. Chicago's largest jail, and the largest single use jail in America, is Cook County.
2023年，该监狱的过量吸毒死亡人数激增。该设施通常平均每年有一到两起过量吸毒死亡事件，当年却有八名囚犯因致命癫痫发作而丧生。监控录像显示，囚犯们出现痉挛并倒地。
In 2023 it saw a spike in overdose deaths. The facility, which averages one or two overdose deaths a year, lost eight inmates that year to fatal seizures. Security footage shows prisoners spasming and collapsing.
传统毒品通常是通过人体腔道被带入监狱的，因此该监狱配备了与机场相同的全身扫描仪来防止这种情况发生。然而，人们发现了一条毒品进入监狱的新途径。毒品被浸泡在书籍的纸张和信件中邮寄进监狱。
Traditional drugs were usually brought into the jail in body cavities, so the jail had the same body scanners you find at airports to prevent that happening. However, a new way of drugs entering the prison was uncovered. Drugs were being mailed into the jail soaked in the paper of the pages of books and in letters.
BBC的昆廷·萨默维尔跟随库克县监狱的惩教人员，准备对该监狱戒备森严的D区进行清晨突袭。
The BBC's Quentin Sommerville joined corrections officers at Cook County as they prepared for an early morning raid on the jail's high security D block.
为了解当局在应对这一问题时面临的挑战，BBC采访了一名前囚犯兼毒贩，他解释了如何在美国使用家用原料制造合成毒品，以及这如何可能改变对来自国外毒品的需求。
To understand the challenge that authorities face in tackling the problem the BBC interviewed a former inmate and dealer, who explained how synthetic drugs can be made in the US using household ingredients and how this could change the demand for drugs from outside of the country.
