The Drug Enforcement Administration says it seized enough fentanyl for 379 million lethal doses in 2022 — twice last year’s amount and enough to kill every person living in the United States and beyond. The DEA is blaming the majority of trafficking on Mexican drug cartels. The World’s host Marco Werman speaks to journalist Sam Quinones, who has written multiple books on drug trafficking and the new era of synthetic drugs in the US. His latest book is, “The Least of Us: True Tales of America and Hope in the Time of Fentanyl and Meth.”
