Los Angeles: "Friends" actor Matthew Perry died from an accidental ketamine overdose, medical examiners said Friday, concluding their investigation into the death of the beloved but troubled TV star.
Perry, who played Chandler Bing on the hit TV sitcom from 1994-2004, died at the age of 54, having been found unconscious in a swimming pool at his house in Los Angeles in October.
He had struggled for decades with addiction to drugs, including ketamine, and related serious health issues, but had reportedly been clean for 19 months prior to his passing.
"Matthew Perry's cause of death is determined to be from the acute effects of ketamine," the Los Angeles County Medical Examiner's office said in a statement.
"Contributory factors in his death include drowning, coronary artery disease and buprenorphine effects. The manner of death is accident. "
Ketamine is illegally used as a recreational drug for its numbing and hallucinogenic effects.
The drug can also be used by doctors as an anesthetic, and researchers are exploring its use as a mental health treatment.
Perry wrote in his memoirs of how he had relied on using ketamine daily at points during his battles with addiction. He said the drug eased his pain and helped with depression.
"Has my name written all over it - they might as well have called it 'Matty,'" he wrote, of ketamine.
"Taking K is like being hit in the head with a giant happy shovel. But the hangover was rough and outweighed the shovel," explained Perry.
'The Big Terrible Thing'
"Friends," which followed the lives of six New Yorkers navigating adulthood and careers, drew a massive global following.
But even as he delivered on-air gag after gag - and earned a fortune - Perry was struggling.
He attended multiple rehabilitation clinics to combat addiction to painkillers. In 2018 he suffered a burst colon, related to drug usage, and underwent multiple surgeries.
In his memoir "Friends, Lovers and the Big Terrible Thing," published last year, Perry described going through detox dozens of times. He dedicated the book to "all of the sufferers out there," and wrote in the prologue: "I should be dead."
"I have mostly been sober since 2001," he wrote, "save for about sixty or seventy little mishaps over the years."
The examiner's report does not specify how or when Perry had consumed the fatal dose of the drug.
But it found that trace amounts were detected in his stomach, and that prescription medications and loose pills were present at his home.
Perry was undergoing medical treatment - but his most recent known infusion was more than a week before his death, meaning that dose would no longer have been in his system.
The examiner's report says the levels of ketamine in Perry's blood were comparable to higher-range levels used as general anesthetic in surgeries, and would cause overstimulation of the heart and problems breathing.
This could have caused Perry to lapse into unconsciousness, with drowning then becoming a contributory cause of death.
Perry's coronary artery disease, and his use of buprenorphine to treat severe pain, would have made him more vulnerable to the effects of ketamine, the report finds.
No alcohol was detected in his system by the autopsy report. Nor were there any traces of other drugs such as cocaine, heroin or fentanyl.
'The 6 of us'
Perry's sudden passing in October drew shocked reactions from Hollywood A-listers, his co-stars, and "Friends" fans worldwide.
"Oh boy this one has cut deep," said Jennifer Aniston, who played Rachel on the show about six close-knit friends navigating adult life in New York.
"He was such a part of our DNA. We were always the 6 of us. This was a chosen family that forever changed the course of who we were and what our path was going to be," she wrote on Instagram.
"The times we had together are honestly among the favorite times of my life," wrote Matt LeBlanc, who played Perry's roommate and best friend on the show.
