Inside the inner circle that fuelled Matthew Perry’s ketamine addiction

Inside the inner circle that fuelled Matthew Perry’s ketamine addiction

May 30, 2026 discoverhiddenusacom Entertainment

Matthew Perry’s loved ones and his Friends co-stars gathered at Forest Lawn Memorial Park to say their final goodbyes. The private event took place just two kilometres away from the studio where the hit sitcom was filmed.

While the occasion was one of mourning, it marked the beginning of a dark revelation regarding the actor’s inner circle. Among the mourners was Kenneth Iwamasa, Perry’s personal live-in assistant, whose role would later be revealed as far more sinister than a typical employee.

A Betrayal of Trust

Kenneth Iwamasa, a friend of 25 years, was hired in 2022 as a live-in assistant with a salary of $US150,000 ($210,000) a year. His primary responsibility was to help Perry maintain his sobriety and manage his medical care.

However, prosecutors revealed that Iwamasa transitioned from a caregiver to an enabler and drug messenger. He used thousands of dollars of Perry’s money to acquire illegal ketamine from crooked doctors and dealers.

Did You Know? Matthew Perry’s final farewell at Forest Lawn Memorial Park occurred just two kilometres away from the studio where the Friends sitcom was filmed.

On the morning of October 23, 2023, Iwamasa injected Perry with substantial quantities of ketamine, despite having no medical training. Hours later, Perry was found floating face down in the hot tub at his Pacific Palisades home.

The LA medical examiner determined the cause of death to be the “acute effects of ketamine,” noting that while Perry drowned in the heated end of his pool, it was a secondary factor in an accidental death.

The Underground Network

The investigation uncovered a sophisticated network of suppliers who preyed upon Perry’s addiction. This group included two doctors, a middleman and a dealer known as the “Ketamine Queen.”

Jasveen Sangha, the “Ketamine Queen,” operated a “drug-selling emporium” for high-profile clients. She was sentenced to 15 years in prison for her role in selling the drugs that led to the actor’s death.

Erik Fleming, a licensed drug addiction counsellor and former acquaintance of Perry, acted as a middleman and was sentenced to two years in prison.

Two doctors were also implicated. Salvador Plasencia, who taught Iwamasa how to administer the drug, was sentenced to 30 months in prison. Mark Chavez received eight months of home detention and three years of supervised release.

Expert Insight: Samantha Carter notes that this case highlights the dangerous intersection of celebrity power dynamics and addiction. When a personal assistant becomes financially and relationally compromised, the boundary between loyalty and enablement can blur, potentially leaving vulnerable individuals without a genuine safety net.

Significance and Consequences

United States Attorney Martin Estrada stated that the defendants cared more about profiting from Mr. Perry than his well-being. The case underscores the vulnerability of individuals battling lifelong addiction when those entrusted with their care prioritize greed.

Perry’s family expressed a profound sense of betrayal. His stepfather, Keith Morrison, noted that the family trusted Iwamasa implicitly, while his sister Madeline described the experience of choosing burial clothes while Iwamasa attempted to distract them from the truth.

Looking Ahead

The conclusion of these sentencings may lead to increased scrutiny regarding the legal responsibilities of personal assistants in medical care roles. There could be a shift in how “discreet” celebrity employment contracts are viewed when they overlap with the administration of controlled substances.

the case may serve as a precedent for how the legal system addresses the “enabler” role in addiction-related deaths, potentially leading to harsher penalties for those in positions of trust.
