“Mark Chavez, a doctor accused of giving ketamine to the late Friends star Matthew Perry, has pleaded guilty to one count of conspiring to distribute the drug. Perry died in October 2023 primarily from the effects of ketamine. His assistant allegedly administered the drug shortly before his death, and he later drowned in the pool of his Los Angeles home. Other factors such as coronary artery disease and the effects of buprenorphine, a medication used to treat opioid use disorder, contributed to his death.” (10/03/24)
