New Synthetic Opioid Cychlorphine Linked to Death of San Francisco Teenager
San Francisco is facing a warning over a newly emerging synthetic opioid after a 16-year-old boy died with the drug in his system.
The teenager, identified in reports as Dante Lacourte, died in April 2026 after an apparent drug overdose. According to the San Francisco Office of the Chief Medical Examiner, his death involved a combination of drugs, including cychlorphine, a relatively new synthetic opioid. San Francisco authorities have described him as the city’s first known death involving the substance.
A drug more powerful than fentanyl
Cychlorphine, also known as N-propionitrile chlorphine, belongs to a group of new synthetic opioids known as orphine opioids. The European Union Drugs Agency is monitoring it as a new psychoactive substance because of concerns about its potential public-health risks.
San Francisco officials have warned that the substance can be around 10 times more potent than fentanyl, making accidental exposure particularly dangerous. Officials have also warned that conventional fentanyl test strips may not detect cychlorphine.
Counterfeit pills raise concern
The investigation into the teenager’s death led San Francisco police to investigate the suspected supply of counterfeit pharmaceutical pills.
On September 8 and 9, police searched several properties and arrested four people. Officers reported seizing more than 20,000 counterfeit pills, along with fentanyl, other narcotics and firearms.
Some counterfeit pills recovered by investigators were suspected to resemble prescription medicines. Authorities have warned that young people could unknowingly consume dangerous synthetic opioids when pills are falsely represented as legitimate medication.
Investigation remains open
Police have said the four arrested suspects face narcotics and firearms charges. However, investigators have not established that the suspects were directly responsible for Lacourte’s death.
San Francisco officials said additional charges could follow if investigators are able to establish a direct connection between a drug sale and the teenager’s fatal overdose.
The case highlights the rapidly changing nature of the illicit-drug market, where newly emerging synthetic substances can appear before authorities and health services fully understand their effects.
A warning to families
The emergence of cychlorphine has prompted concerns about teenagers and counterfeit pills sold through illicit markets and social-media channels.
Health authorities stress that illegally manufactured pills can contain unexpected substances and potentially fatal quantities of synthetic opioids.
The key message from officials is that a pill that looks like a prescription medication may not actually contain the drug it claims to contain.
