Doctor allegedly provided Matthew Perry with ketamine so he could resume his practice | Matthew Perry

A doctor accused of illegally supplying Friends star Matthew Perry with ketamine before his death from an accidental overdose last year plans to resume his medical practice this week.

Dr. Salvador Plasencia's attorney confirmed to NBC News that the doctor plans to resume his practice at the urgent care clinic he runs in Calabasas, a city in the San Fernando Valley in Los Angeles County.

Last week, Plasencia pleaded not guilty to one count of conspiracy to distribute ketamine and was released on $100,000 bail. A judge overseeing his case ruled that he must post a sign on the door of his clinic informing potential patients of his upcoming trial.

In addition, Plasencia's patients must sign a form at each visit declaring that they understand the allegations against him and consent to treatment.

Prosecutors allege that Perry was injected with ketamine at least 20 times in the days before his intoxicated and drowning death in a hot tub in October of last year, and that he was given three injections in the hours before his death.

The last time, Perry allegedly instructed his assistant, Kenneth Iwamasa, to “give him a large dose” and prepare the hot tub. The assistant administered the dose to Perry and left the house to run errands, the papers say. When he returned, Perry was lying face down in the water.

Prosecutors allege that Plasencia gave Iwamasa ketamine and that he also administered injections of the drug to Perry himself and taught the assistant how to administer them.

Perry had been undergoing ketamine treatment to treat depression, but reportedly sought alternative sources of the drug when the clinic began restricting dosages. Prosecutors said the actor obtained the drug illegally outside of his scheduled dosages, as part of an “out-of-control” addiction.

The drug has become very popular as an alternative treatment, with users praising the feeling of going down a rabbit hole and entering an egoless state.

Iwamasa pleaded guilty to conspiracy to distribute ketamine causing a death and administering injections without medical training. According to prosecutors, Perry had a scheduled ketamine infusion with a doctor on Oct. 14, two weeks before his Oct. 28 death.

That day, the assistant contacted Plasencia to get more of the drug, and the doctor arranged to meet at Perry's home and administered a “large dose of ketamine.” But Perry reacted to the extra dose and his body began to “freeze.”

With Iwamasa's permission, Plasencia left additional vials of ketamine for the actor at his home. But Perry wanted more and instructed Iwamasa to contact another supplier.

Documents released by the court show that Plasencia obtained ketamine from another doctor charged in the case, Dr. Mark Chavez, who previously ran a ketamine clinic. Chavez allegedly provided a fake ketamine prescription for Plasencia to give to Perry.

Iwamasa said he purchased about $55,000 worth of ketamine in the month before Perry's death from various sources, including, according to the indictment, Plasencia, “ketamine queen” Jasveen Sangha, Chavez and drug broker Erik Fleming.

At one point, Chavez Plasencia is said to have sold at least four vials of liquid ketamine and ketamine lozenges valued at $2,000.

In a September 2023 text message to Chavez, Plasencia described his visit to Perry's house as “like a bad movie.” After a visit to the actor's home a month later, Plasencia wrote to Chavez: “[If] If today goes well, we might come back.”

“Let’s do everything we can to make it happen,” Chavez is said to have replied.

According to court documents, Plasencia and Chavez also discussed how much to charge Perry. “I wonder how much this idiot is going to pay,” Plasencia texted Chavez. Chavez reportedly responded, “Let's find out.”
