Designer opioid cychlorphine linked to teen death triggers nationwide warnings

TL;DR
A San Francisco teen’s death is tied to cychlorphine, a newly detected synthetic opioid said to be up to 10x more potent than fentanyl. The drug often appears in counterfeit pills or mixed with other substances, is hard to detect with standard tests, and may require multiple naloxone doses to reverse an overdose. Federal and local officials have issued warnings, and the DEA has placed cychlorphine on Schedule I as its presence spreads across several states.
