Sangha is one of five people to have been convicted for playing a part in the star’s death.
Dr Salvador Plasencia, who admitted four counts of distribution of ketamine in the weeks before Perry’s death, was last year sentenced to 30 months in jail.
Another doctor, Mark Chavez, was eight months of home detention and three years of supervised release.
Plasencia bought ketamine off Chavez and sold it to Perry for massively inflated prices – $2,000 (£1,500) per vial. “I wonder how much this moron will pay,” Plasencia wrote in one text message, the court heard.
Sangha worked with an intermediary, Erik Fleming, to sell 51 vials of ketamine to Perry’s personal assistant, Kenneth Iwamasa.
Iwamasa repeatedly injected Perry with the drugs including on 28 October 2023, when he administered at least three shots that ultimately led to the actor’s death.
Sangha then instructed Fleming to “delete all our messages”.
Iwamasa and Fleming are scheduled to be sentenced later this month.
