Assistant Who Gave Matthew Perry Ketamine Sentenced to Over Three Years in Prison

AI Summary
Kenneth Iwamasa, the personal assistant who repeatedly injected Matthew Perry with ketamine, received a prison term of three years and five months. The sentencing concludes a multi‑person investigation into the actor’s fatal overdose and highlights growing scrutiny of unlicensed drug distribution in celebrity circles.

Court Hands Assistant Over Three‑Year Prison Term

On 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 Ketamine

From 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 Penalties

  • Kenneth Iwamasa: 3 years 5 months prison
  • Jasveen Sangha (ketamine supplier): 15 years prison
  • Erik Fleming (middleman): 2 years prison
  • Salvador Plasencia (doctor who supplied Iwamasa): 30 months prison
  • Mark Chavez (doctor who sold ketamine to Perry): 8 months home detention + 3 years supervised release

The court’s decisions reflect the varying degrees of culpability, from direct administration to supply chain facilitation.

Broader Implications for Celebrity Assistance and Drug Regulation

The 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 Measures

Legal 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.
