Matthew Perrys former assistant sentenced for lethal ketamine injection

Published on May 29, 2026 | Translated from Spanish

Kenneth Iwamasa, Matthew Perry's former personal assistant, was sentenced to three years and five months in federal prison for administering lethal doses of ketamine to the actor. The case, involving five people, highlights failures in the drug's supply and administration chain. Iwamasa confessed to injecting the actor without medical training, following instructions from a doctor implicated in the scheme.

The Ketamine Supply Chain: A Vulnerable System ⚖️

The case reveals how ketamine, a dissociative anesthetic with applications in depression therapies, can be diverted from clinical use to recreational consumption. The sentence includes two years of supervised probation and a $10,000 fine. The distribution network operated without adequate controls, allowing the assistant to obtain the drug without a prescription or supervision, a pattern the FDA and DEA seek to eradicate through digital traceability systems.

The Recipe for Disaster: No Medical Degree, But Doses 💉

Iwamasa, without a white coat or nursing degree, became Perry's go-to anesthesiologist. The famous Ketamine Queen is also implicated, proving that to be the king of parties, all you need is a drug briefcase and zero scruples. In the end, the assistant received his own dose of justice: three years in prison, though without the hallucinogenic effect.
