The death of American actor Matthew Perry, star of the television series "Friends", was caused by "the acute effects" of taking ketamine, the Los Angeles County Forensic Pathology Office announced on Friday, December 15. However, other factors also contributed to his death, which was determined to be an "accident," the same source detailed: "drowning," "coronary artery disease," and "effects of buprenorphine," a drug used to treat opioid addiction.
Ketamine is an anesthetic that is sometimes misused for recreational purposes.
