UK Ministers develop an early warning system to detect synthetic opioids like fentanyl, using waste water and emergency service data.

UK Ministers develop an early warning system to detect synthetic opioids, such as fentanyl, to prevent a US-style crisis. The system will test waste water and overdose spikes reported by emergency services to track drug presence and strength in real time. Crime and Policing Minister Chris Philp aims to raise public awareness about the risks of synthetic opioids, which are more toxic than better-known drugs like heroin.
