'Friends' star Matthew Perry died Oct. 28 after being injected with ketamine
Two doctors among those charged in Matthew Perry's death
Constitutional law attorney Katie Cherkasky and former DEA special operations director Derek Maltz say the doctors should be held to a higher standard as they are facing charges for providing ketamine to Matthew Perry.
Dr. Mark Chavez was allowed to remain free on bond after conspiring to distribute surgical anesthetic ketamine to late actor Matthew Perry.
Chavez appeared in Los Angeles court on Friday after reaching a plea agreement earlier this month. U.S. Magistrate Judge Jean P. Rosenbluth told him he could remain free on bond with several restrictions, including turning over his passport and not working as a doctor.
Chavez did not enter his guilty plea or speak about the case, which he will do with another judge at a date to be determined.
After entering his guilty plea, Chavez could be sentenced to a maximum of 10 years in prison.

Perry's death on Oct. 28 was caused by "acute effects of ketamine," according to his autopsy, which was completed on Oct. 29. Drowning, coronary artery disease and buprenorphine effects were listed as contributing factors.

Chavez agreed to plead guilty to one count of conspiracy to distribute ketamine as part of his plea agreement. The San Diego-based doctor admitted to selling ketamine to Dr. Salvador Plasencia, including ketamine that he had diverted from his former clinic.
Chavez previously ran a ketamine clinic and allegedly submitted a bogus prescription in the name of a former patient to secure the drug. Plasencia allegedly taught Perry's assistant how to inject the actor with the drug.
Perry had been looking to find an additional ketamine source in the month before his death after the doctor he had been using wouldn't give him more of the drug, according to court documents obtained by Fox News Digital.

Three others were charged in connection to Perry's death.
Perry's assistant, Kenneth Iwamasa, pleaded guilty on Aug. 7 to one count of conspiracy to distribute ketamine, causing death. Iwamasa admitted to repeatedly injecting Perry with ketamine without medical training, including performing multiple injections on the day Perry died.

Jasveen Sangha, aka "The Ketamine Queen," was charged with one count of conspiracy to distribute ketamine. She is also charged with one count of maintaining a drug-involved premises, one count of possession with intent to distribute methamphetamine, one count of possession with intent to distribute ketamine and five counts of distribution of ketamine.
Erik Fleming, who admitted to working as a middleman between Sangha and Iwamasa, pleaded guilty on Aug. 8 to one count of conspiracy to distribute ketamine and one count of distribution of ketamine resulting in death. Fleming admitted in court documents that he distributed the ketamine that killed Perry.

The ketamine allegedly provided by Sangha and delivered to Iwamasa by Fleming killed Perry on Oct. 28, according to court documents.
That morning, Perry's assistant administered a shot of ketamine to the actor around 8:30. By 12:45 p.m., Perry had instructed Iwamasa to give him another injection while the "Friends" star watched a movie. Roughly 40 minutes later, Perry requested another injection, allegedly telling Iwamasa, "Shoot me up with a big one," according to the plea agreement.
The live-in assistant administered a third injection to Perry while the 54-year-old was near or in a Jacuzzi. Iwamasa then left the home to run errands for Perry. When he returned, the assistant found Perry "face down" in the Jacuzzi, deceased.
The three then worked together to cover up their involvement in Perry's death, authorities alleged.
