In a tragic turn of events, the cause of actor Matthew Perry's death has been confirmed, nearly two months after he was found dead at his home. ET has obtained Perry's autopsy report, shedding light on the circumstances surrounding his untimely passing.

The report states that Perry's cause of death was the acute effects of ketamine, a powerful anesthetic commonly used for medical and veterinary purposes. Perry was apparently undergoing ketamine infusion therapy to manage his depression and anxiety. However, it is noted in the report that the ketamine found in his system could not be from his last known treatment, as the drug's half-life is less than four hours.

Drowning, coronary artery disease, and the effects of buprenorphine, a medication used for opioid dependence, were listed as contributing factors to Perry's cause of death. The report suggests that his death was accidental, related to drug use and drowning, with no foul play suspected.

While prescription medications and loose pills were discovered at Perry's home, the report states that none were found near the pool where he died.

The release of the autopsy report comes a month after Perry's death certificate was obtained by ET. According to the certificate, Perry passed away on October 28, 4:17 p.m., at his home. The informant on the certificate was Perry's stepfather, Keith Morrison, who identified the actor to authorities.

Perry was laid to rest at Forest Lawn Memorial Park in Los Angeles on November 3, as stated in the death certificate. The funeral was attended by Perry's beloved Friends co-stars Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, and David Schwimmer, along with other close friends and family members.

This news brings closure to the fans and loved ones of Matthew Perry, as the details of his cause of death are now known. May he be remembered for his contributions to the entertainment industry and the joy he brought to audiences worldwide.
