Court Hands Assistant Over Three‑Year Prison TermOn Wednesday, a Los Angeles judge sentenced Kenneth Iwamasa, 61, to three years and five months in federal prison for distributing ketamine that led to the death of Matthew Perry. The punishment aligns with prosecutors’ request and caps the criminal probe into the five individuals linked to Perry’s 2023 overdose.Assistant’s Direct Role in Administering KetamineFrom 2022 to 2023 Iwamasa served as Perry’s live‑in personal assistant. In the three days before the actor was found dead in a hot tub, Iwamasa injected him with six to eight ketamine shots per day, according to court documents. Prosecutors say Iwamasa paid former doctor Salvador Plasencia at least $55,000 to obtain the drug, and also coordinated with drug dealer Jasveen Sangha and addiction counselor Erik Fleming.Sentencing Numbers and Comparative PenaltiesKenneth Iwamasa: 3 years 5 months prisonJasveen Sangha (ketamine supplier): 15 years prisonErik Fleming (middleman): 2 years prisonSalvador Plasencia (doctor who supplied Iwamasa): 30 months prisonMark Chavez (doctor who sold ketamine to Perry): 8 months home detention + 3 years supervised releaseThe court’s decisions reflect the varying degrees of culpability, from direct administration to supply chain facilitation.Broader Implications for Celebrity Assistance and Drug RegulationThe case underscores the power imbalance between high‑profile clients and personal staff, a dynamic that can enable illicit drug access. Hollywood insiders noted that assistants often lack the authority to refuse dangerous requests, raising questions about workplace protections and the need for stricter oversight of non‑medical personnel handling controlled substances.Looking Ahead: Tighter Enforcement and Preventive MeasuresLegal experts predict increased federal scrutiny of unlicensed drug distribution networks, especially when they intersect with celebrity circles. Expect more rigorous background checks for personal assistants, heightened monitoring of ketamine prescriptions, and potential legislative proposals to criminalize the facilitation of controlled‑substance use without medical credentials.
