Dr Salvador Plasencia, who admitted four counts of distribution of ketamine in the weeks before Perry’s death, was last year ordered to serve 30 months in jail.
Another doctor, Mark Chavez, was ordered to be confined at home and told to do hundreds of hours of community service.
Plasencia bought ketamine off Chavez and sold it to the American-Canadian actor at hugely inflated prices.
“I wonder how much this moron will pay,” Plasencia wrote in one text message.
Prosecutors said Perry was paying more than US$2000 ($3400) per vial of ketamine; his dealers paid a fraction of that.
Sangha worked with a middleman, Erik Fleming, to sell 51 vials of ketamine to Perry’s live-in personal assistant, Kenneth Iwamasa.
Iwamasa repeatedly injected Perry with the ketamine that Sangha had supplied, including on October 28, 2023, when he administered at least three shots of drugs, which killed the actor.
When Sangha heard news reports about Perry’s sudden death, she tried to cover her tracks.
“Delete all our messages,” she instructed Fleming.
When investigators raided Sangha’s home in North Hollywood, they found methamphetamine, ketamine, ecstasy, cocaine and counterfeit Xanax pills, as well as a money-counting machine, a scale and devices to detect wireless signals and hidden cameras.
