5 Shocking Revelations From Matthew Perry's Autopsy Report: The Tragic Truth Of His Final Hours
The world was stunned on October 28, 2023, by the sudden passing of beloved actor Matthew Perry, best known for his iconic role as Chandler Bing on the hit sitcom Friends. For months, the public and his devoted fanbase waited for the official determination of his death, which occurred at his Los Angeles home. The final toxicology and autopsy reports, released in December 2023, delivered a tragic and complex answer, confirming the actor's long-documented struggle with addiction played a fatal role in his final hours. As of today, December 23, 2025, the full details paint a somber picture of an accidental death involving a potent anesthetic, heart disease, and drowning.
The Los Angeles County Department of Medical Examiner's findings ruled the death "accidental," but the specific factors involved have raised serious questions about the circumstances and the source of the lethal substance. This article breaks down the official findings, the key contributing factors, and the ongoing criminal investigation that followed the tragic event.

The Official Cause of Death: Acute Effects of Ketamine
The primary finding from the Los Angeles County Medical Examiner was that Matthew Perry died from the "acute effects of ketamine." This ruling was based on the toxicology report, which revealed very high levels of ketamine in his system—levels typically associated with general anesthesia. Ketamine is a powerful dissociative anesthetic that is also used recreationally for its hallucinogenic and sedative effects.
The report specified that the actor had been receiving Ketamine Infusion Therapy (KIT) to treat depression and anxiety. However, the medical examiner noted a critical discrepancy: the half-life of ketamine is short, and his last known infusion was approximately one-and-a-half weeks before his death. The extremely high levels found in his postmortem blood indicated that the ketamine in his system at the time of death could not have been from his last therapeutic session. This strongly suggested a non-therapeutic, recreational intake of the drug shortly before he died.
Ketamine can cause cardiovascular stimulation and respiratory depression. In Perry’s case, the drug is believed to have caused overstimulation of his heart and central nervous system depression, leading to a loss of consciousness.
5 Critical Revelations from the Autopsy and Investigation
The official autopsy report and the subsequent criminal investigation revealed several shocking factors that contributed to the actor's accidental death, providing a clearer picture of the tragic event.
1. Drowning Was a Major Contributing Factor
Matthew Perry was discovered unresponsive in the hot tub at his Pacific Palisades home by his assistant. The autopsy listed "drowning" as a contributing factor to his death. The theory is that the high levels of ketamine caused him to lose consciousness while in the water, rendering him unable to keep his head above the surface. Drowning, combined with the other factors, proved fatal. The scene of the death was a stark and lonely end for the man who brought so much laughter to millions.
2. The Role of Coronary Artery Disease
Another significant factor listed in the report was Coronary Artery Disease (CAD). CAD is a common condition that affects blood flow to the heart. While not the primary cause, the presence of CAD meant that Perry's heart was already compromised. The stress and stimulation caused by the high levels of ketamine would have been significantly more dangerous to a heart affected by CAD, accelerating the cardiac effects that preceded his unconsciousness.
3. Buprenorphine Complicated the System
The autopsy also cited the "effects of buprenorphine" as a contributing factor. Buprenorphine is a medication often used to treat opioid use disorder, helping to manage withdrawal symptoms and cravings. While not a direct cause of death, the presence of this opioid-based medication in his system, combined with the powerful sedative effects of ketamine, would have compounded the respiratory depression and central nervous system slowdown, increasing the risk of losing consciousness and subsequent drowning.
4. The Source of Ketamine Led to a Criminal Probe
The medical examiner's conclusion that the fatal dose of ketamine was not from a prescribed therapeutic infusion immediately triggered a criminal investigation by the Los Angeles Police Department (LAPD) and the U.S. Drug Enforcement Administration (DEA). The focus of the probe was to determine how Perry obtained the ketamine he consumed on the day of his death. This investigation sought to identify the individuals who may have illegally provided the drug to the actor.
5. Doctor and Assistant Sentenced in Connection
The criminal investigation, which is a key fresh detail, has already led to legal action. In a significant development, a second doctor was sentenced in late 2024 to 8 months of home detention and 3 years of supervised release after pleading guilty to conspiracy to distribute ketamine in connection with Perry's death. Additionally, another individual, identified as a doctor who helped sell ketamine to the actor, avoided prison time but was sentenced. These developments underscore the seriousness of the non-therapeutic drug supply chain and the tragic outcome of illicit drug use, even for someone in recovery.
The Tragic Intersection of Fame and Addiction
Matthew Perry’s memoir, *Friends, Lovers, and the Big Terrible Thing*, was a raw and honest account of his life-long battle with substance abuse, an entity that stalked him throughout his career. He openly discussed his goal of helping others struggling with addiction, famously stating, "The best thing about me, bar none, is that if somebody comes up to me and says, 'I can't stop drinking, can you help me?' I can say, 'Yes.'"
His death is a profound tragedy, not just for the loss of a brilliant actor, but as a stark reminder of the insidious nature of addiction. The combination of ketamine, buprenorphine, and an underlying heart condition created a lethal scenario, ultimately ruling his death an accidental drowning due to drug effects. The ongoing investigation and the sentencing of individuals involved in the ketamine supply chain serve as a somber final chapter to his story, emphasizing the dangers of recreational drug use, even in the context of recovery and mental health treatment.
