A federal judge in Los Angeles on Friday revoked the license of one of two doctors accused in the ketamine overdose death of actor Matthew Perry.

Mark Chavez, 54, accepted a plea deal with prosecutors and is expected to plead guilty to assisting in the illegal supply of ketamine. The death of Matthew Perry – who was hugely popular as ‘Chandler’ in the TV series ‘Friends’ – in October 2023 shocked Hollywood.

Another doctor, Salvador Placencia, is accused of buying ketamine from Chavez to sell at a much higher price to Matthew Perry. Jasvin Sangha, known by the nickname “the queen of ketamine”, is accused of supplying the dose that killed the 54-year-old actor.

Their trial is scheduled for October. Until then, Mark Chavez is expected to plead guilty to avoid trial. Through his lawyer, he said he was “regretful” for his act. “My client accepts (his) responsibility. He’s doing everything he can to cooperate … and he’s incredibly remorseful,” Matt Binninger told reporters outside court.

This anesthetic, sometimes abused for stimulation or euphoria, was originally taken by the actor under supervision as part of sessions to treat depression. But when he was denied a dose increase, Matthew Perry turned elsewhere.

A federal Drug Enforcement Agency (DEA) official described Placencia and Chavez as “rogue” doctors who “violated the Hippocratic Oath.”
