Friends star Matthew Perry’s death has been ruled an accident from the “acute effects of ketamine”, a post-mortem has found.
Contributing factors in Perry‘s death included drowning, coronary artery disease and the effects of buprenorphine (used to treat opioid use disorder), officials said.
An autopsy report stated that Perry was “receiving ketamine infusion therapy for depression and anxiety” with the most recent dose reportedly taken one and a half weeks before his death.
The report continued: “The ketamine in his system at death could not be from that infusion therapy, since ketamine’s half-life is three-to-four hours, or less.”
The actor was found unresponsive in the swimming pool at his home on 28 October and pronounced dead at the age of 54 by paramedics at the scene.
A post-mortem was carried out the following day.

Perry’s cause of death comes days after Aniston revealed she had been messaging him on the morning of his death, describing him as “happy and healthy”.
“I want people to know he was really healthy, and getting healthy. He was on a pursuit. He worked so hard. He really was dealt a tough one,” she told Variety.
