Dr. Salvador Plasencia exploited Matthew Perry’s addiction for profit. In September 2023, he texted a co-conspirator: “I wonder how much this moron will pay.”
He then supplied illegal ketamine during the weeks before Perry died in October. On December 3, 2025, Judge Sherilyn Peace Garnett sentenced the 44-year-old Santa Monica physician to 30 months in federal prison for four felony counts of ketamine distribution.
She fined him $5,600 and remanded him to custody immediately. His case marks a rare federal prosecution of a licensed physician for distribution tied to a celebrity overdose.
Timeline of Betrayal
In late September 2023, Plasencia learned Perry wanted ketamine and contacted Dr. Mark Chavez, a San Diego physician who ran a ketamine clinic.
Between September 30 and October 12, Plasencia distributed 20 vials of liquid ketamine, ketamine lozenges, and syringes to Perry and his assistant, Kenneth Iwamasa.
Perry paid roughly $57,000 over 13 days—a massive markup from the $12-per-vial street price. Two weeks after Plasencia’s final delivery on October 12, Perry drowned in his Pacific Palisades hot tub on October 28, age 54.
The Medical Premise
Ketamine has legitimate medical uses. For decades, doctors used it as a surgical anesthetic with FDA approval. Recently, esketamine (a ketamine variant) gained FDA approval for treatment-resistant depression—severe depression that resists at least two conventional antidepressants.
Doctors must administer the FDA-approved version in-office with cardiac monitoring. However, the FDA has not approved ketamine for at-home psychiatric use, and compounded versions operate in regulatory gray areas.
Perry received supervised ketamine therapy at a legitimate clinic for depression and anxiety—until his doctors refused to increase his dosage.
Where Supervision Ended
When legitimate clinicians refused Perry’s requests for higher doses, he turned to unscrupulous practitioners. Federal prosecutors stated that Perry, with decades-long public struggles against addiction, sought illegal suppliers willing to prioritize profit over ethics.
This is where Plasencia’s criminal enterprise began. Instead of recognizing Perry’s escalating dependency as a clinical red flag, Plasencia saw a wealthy, vulnerable addict—an opportunity.
Prosecutors alleged Plasencia learned Perry would pay premium prices for ketamine, turning “$12 vials” into “$2,000 fees.” Supplying Perry despite knowing his addiction history represented a catastrophic breach of medical ethics.
The Damning Texts
In September 2023, Plasencia and Dr. Chavez exchanged texts revealing calculated exploitation. Plasencia wrote: “I wonder how much this moron will pay,” and told Chavez, “Let’s find out.” Prosecutors used these messages to prove premeditated targeting.
Plasencia treated Perry not as a patient but as a mark. The texts documented Plasencia and Chavez discussing inventory, pricing, and ketamine availability specifically to sell to Perry. They met three times in September and October 2023 to coordinate the supply of materials.
Chavez obtained at least 22 vials of liquid ketamine and nine lozenges through fraudulent prescriptions to pharmaceutical wholesalers.
Methods of Administration
Plasencia didn’t merely supply pills or prescriptions. He personally administered ketamine to Perry at least seven times between late September and mid-October 2023.
He appeared at Perry’s home and met him in public locations, including an aquarium parking lot in Long Beach, 25 miles south of Los Angeles, to inject the drug directly.
Prosecutors alleged Plasencia taught Perry’s assistant Kenneth Iwamasa, who had no medical training, how to inject ketamine. Plasencia left vials for unsupervised use.
Iwamasa later admitted to injecting Perry six to eight times daily in Perry’s final days, including October 28.
The Escalation Pattern
Perry’s addiction spiraled visibly. Court documents reveal prosecutors learned Perry’s consumption was accelerating—and Plasencia knew this. Yet he continued supplying.
One week before his final delivery on October 27, Plasencia texted Iwamasa: “I have been stocking up in the meantime. I am not sure when you guys plan to resume, but in case it’s when I’m out of town this weekend, I have left supplies with a nurse of mine.”
This message showed Plasencia preparing for continued supply despite Perry’s increasing consumption—classic exploitation behavior rather than medical care.
Fatal Dose Source
The ketamine that killed Perry came from another source: drug dealer Jasveen Sangha, the “Ketamine Queen.” Court evidence shows Perry received ketamine from multiple defendants simultaneously.
Sangha pleaded guilty in September 2025 to five charges, including the distribution of ketamine resulting in death. She admitted knowing Perry was the intended customer when she provided 50 vials through intermediary Erik Fleming.
The autopsy showed Perry ingested approximately 2.2 grams of ketamine—an anesthetic-level dosage used in surgery. Perry’s last legitimate ketamine treatment occurred a week-and-a-half before his death, meaning he self-administered the fatal dose on October 28.
Contributing Medical Factors
Multiple bodily insults caused Perry’s death. The medical examiner identified the primary cause as “acute effects of ketamine,” with three contributing factors: drowning (ketamine rendered him unconscious in the hot tub), coronary artery disease (existing heart condition), and buprenorphine (an opioid-addiction medication that reacts dangerously with ketamine).
Ketamine overstimulated Perry’s cardiovascular system and depressed his respiration. Medical experts note that people with hypertension or cardiac conditions face heightened ketamine risk at high doses. Perry fit this profile: decades of substance abuse had damaged his heart.
No defendant screened him for these contraindications before supplying anesthetic-level dosages.
Plasencia’s Calculated Indifference
Evidence suggested deliberate negligence rather than accidental over-prescription. Plasencia held a medical degree and managed an urgent-care clinic—he understood the risks of ketamine.
Prosecutors alleged he recognized Perry’s addiction escalation but prioritized revenue. Plasencia charged roughly $4,500 per visit and obtained vials at wholesale cost from Dr. Chavez, generating extraordinary profit margins.
His defense claimed he was a “compassionate doctor” who “made serious mistakes.” However, the texts and transactions painted a different picture: a physician using medical knowledge to exploit vulnerability.
Supplying 20 vials over 13 days—versus supervised protocols delivering single doses—revealed calculated recklessness.
Perry’s Family Confronts Plasencia
The sentencing hearing became a forum for familial anguish. Perry’s mother, Suzanne Morrison, stood directly facing Plasencia and said softly, “I just want you to see his mother.”
Perry’s stepfather, Keith Morrison (NBC Dateline correspondent), submitted a 1,400-word victim impact statement calling Plasencia “the most culpable of all.” Morrison wrote: “This doctor conspired to break his most important vows repeatedly, sneaked through the night to meet his victim in secret.
For what, a few thousand dollars?” He termed Plasencia and co-conspirators “greedy jackals” who exploited Perry’s public addiction struggles. Perry’s father and stepmother told Plasencia, “You don’t deserve to hear our feelings.”
Perry’s Third Act Stolen
The family emphasized Perry’s recovery trajectory before the conspiracy derailed it. Perry documented his addiction struggles in his 2022 memoir “Friends, Lovers, and the Big Terrible Thing.” He actively worked on recovery and secured a movie comeback—what Morrison called “a third act.”
Perry had a two-year-old godson and stable relationships. The victim impact statement noted: “Life so entwined with ours and held aloft sometimes with duct tape and baling wire”—yet recovery seemed achievable.
“And then those greedy jackals come out of the dark, and all the effort is for naught; it all crashes down,” Morrison lamented. The family’s testimony revealed not merely a death but the destruction of redemption.
Plasencia’s Reckoning in Court
During sentencing, Plasencia expressed remorse. He told the court, “I should have protected him, as his mother articulated. I am just so sorry.” His attorneys acknowledged “the mistakes he made during the 13 days he treated Mr. Perry will stay with him forever.”
His own mother wept in the courtroom gallery as Plasencia was handcuffed. He mentioned his two-year-old son, expressing worry about explaining his crimes: “I want to raise him right.”
His legal team argued he rose from poverty to become a physician beloved by clinic patients, that his crime was aberrational, and that he’d already lost his career and medical license, deserving mercy rather than prison.
The Judge’s Sentence
Judge Sherilyn Peace Garnett rejected appeals for leniency. She sentenced Plasencia to 30 months (2.5 years) in federal prison, two years of supervised release, and a $5,600 fine, plus a $400 assessment.
Prosecutors requested three years; Perry’s family sought harsher punishment. The sentence fell short of the 40-year maximum available under Plasencia’s plea agreement but reflected the judge’s assessment of his culpability.
Garnett emphasized that although Plasencia didn’t provide the fatal dose, he enabled Perry’s addiction and violated fundamental medical ethics. Immediately after sentencing, officers took Plasencia into federal custody in the courtroom to begin his sentence without time to prepare for his family affairs.
Four Sentencings Pending
Plasencia’s sentencing launched a cascade of court dates. Dr. Mark Chavez, the San Diego physician who supplied ketamine to Plasencia, faces sentencing on December 17, 2025.
Jasveen Sangha, known as the “Ketamine Queen,” is scheduled to be sentenced on February 25, 2026, after being initially set for December 10. Erik Fleming, the middleman dealer who connected Perry to Sangha, is scheduled to face sentencing on January 7, 2026.
Kenneth Iwamasa, Perry’s assistant who administered fatal injections without training, will be sentenced on January 14, 2026. Maximum potential sentences range from 10 years (Chavez) to 65 years (Sangha). The staggered schedule keeps Perry’s case in public focus through early 2026.
Medical Regulation Gaps Exposed
Plasencia’s case exposed critical regulatory vulnerabilities in the distribution of ketamine. The FDA approved esketamine nasal spray (Spravato) for treatment-resistant depression in January 2025, but compounded ketamine—liquids, lozenges, oral forms—largely escapes FDA oversight.
Clinics operate in regulatory gray zones, prescribing off-label ketamine with minimal requirements. The FDA has not approved ketamine for any psychiatric disorder through standard pharmaceutical channels.
Yet as of early 2025, over 140,000 patients received esketamine, and hundreds of ketamine clinics nationwide offer at-home treatments without physician presence. California’s Medical Board suspended Chavez’s license and revoked Plasencia’s—but only after deaths occurred.
Lawmakers and medical societies now debate standards to prevent future exploitations.
Ketamine Industry Crossroads
Perry’s case poses existential questions for legitimate ketamine therapy. Researchers at Yale and major universities published evidence that ketamine produces rapid antidepressant effects—within 24 hours versus the two-month timeline of conventional antidepressants.
For treatment-resistant depression, ketamine offers hope when other drugs fail. However, Perry’s case demonstrates that vulnerable populations—particularly those with addiction histories—face extreme risk in unsupervised settings.
Medical societies now debate screening protocols: Should doctors exclude people with documented addiction histories from ketamine therapy? Should at-home administration be banned? Should licensing requirements tighten?
These debates will reshape access to a potentially lifesaving treatment, forcing clinicians to balance efficacy with safety.
Public Perception and Misinformation
Public reaction to Perry’s case has been visceral and polarized. Social media initially mischaracterized Plasencia as uniformly “evil”; deeper reporting revealed a complex picture of greed, recklessness, and institutional failure.
Misinformation claimed Perry “went to a drug dealer” when he initially sought legitimate treatment and only turned to illegal sources when clinic doctors appropriately refused escalation. Some accounts falsely suggested Plasencia caused Perry’s death—overlooking that Sangha supplied the fatal dose.
Mental health advocates worried the case would stigmatize ketamine therapy entirely, deterring depressed patients from potentially helpful treatment. News coverage evolved to reflect the five-defendant conspiracy rather than singular villainy, reducing sensationalism.
Precedent in Medical Prosecution
Plasencia’s case joins a rare category of federal prosecutions targeting licensed physicians for drug distribution beyond surgical contexts. It parallels opioid epidemic prosecutions of doctors like pain specialist Nouri Safadi (sentenced to 40 years in 2022), who prescribed dangerously to known addicts.
However, ketamine differs from opioids: it has genuine psychiatric applications and FDA-approved formulations. This distinction complicated prosecution narratives. Prosecutors bore the burden of proving Plasencia violated medical standards rather than merely breaking regulations.
The outcome establishes that physicians supplying high-dose ketamine to vulnerable addicts—especially when profit motivation is documented—face serious federal penalties. This potentially chills both legitimate and reckless prescribing.
The Fundamental Betrayal
Perry’s death exposes how addiction vulnerability creates opportunity for medical exploitation. Perry sought legitimate treatment, paid for it, and followed clinical protocols until the doctors responsibly refused to escalate. At that inflection point—when a patient’s addiction redlined—the system failed.
Instead of coordinated intervention (addiction specialists, family counseling, psychiatric support), Perry encountered Plasencia: a physician who recognized addiction not as a clinical emergency but as a sales pipeline. The $2,000-per-vial business model, secret meetings, and escalating supplies, despite visible deterioration, reflected a calculated indifference masquerading as medicine.
Plasencia’s 30-month sentence sends a message: physicians cannot exploit addiction for profit without consequences. Yet thousands of Americans with addiction histories seeking psychiatric treatment still encounter inadequate safeguards and practitioners willing to breach ethics for financial gain.
