Deaths involving fentanyl rise as curbing illicit supply proves tough

Keeping up with the inventive chemists sounds nearly impossible

To get in front of production, the State Department and a group of U.S. senators asked the United Nations in October to add to the list of tightly controlled substances two key ingredients used to make fentanyl. Clandestine labs across China are the main source of the illegally sold fentanyl. Producers then ship the drug to Mexico, where drug cartels mix it into heroin or press it into tablets that look like prescription pills for anxiety or pain. The powder or pills are delivered to dealers, or directly to users, via the Internet or darknet, an online area used for illegal purchases.
