“I'm not great at the advice. Can I interest you in a sarcastic comment?”

This is what ‘Friends’ actor Matthew Perry’s character Chandler Bing was known for. He was known for being funny. However, he had his own struggles in his personal life and those struggles were acute depression. He was treating it with ketamine infusion therapy which is legal in the US and the UK.

What is Ketamine infusion therapy?

Ketamine is an anaesthetic used to treat depression, anxiety and pain under supervised and controlled medical settings. However, it does have its side effects, which can lead to distortion of sight, sound and time. It can also produce calming and relaxing effects.

Ketamine increases a person’s heart rate and blood pressure. If overdosed, it can leave users confused and agitated and can cause them to hurt themselves without even realising it. It can also lead to liver damage and bladder problems.

However, when used in moderation and under the supervision of medical doctors, it can treat depression where traditional antidepressants have failed.

Prof Rupert McShane, a University of Oxford psychiatrist who runs an NHS ketamine treatment clinic told BBC that ketamine “probably turns off the area of the brain that is involved in disappointment.”

Can Ketamine Infusion Therapy Kill Someone?

In simple terms, it cannot, be if the dosage is given in a controlled setting and as prescribed. Ketamine infusion therapy uses drugs in small doses than those used for anaesthesia. It acts faster than traditional anti-depressants, but the effects also wear off way quickly. Which is why it is important to monitor patients’ mental state for relapsing back into depression and discouraging them from overdosing on it.

There are ways of giving people ketamine. One of the ways is through “infusing”, which means to use an IV drip. However, injections, nasal sprays and capsules are also methods used to give people ketamine.

Since the dosage of ketamine used in the infusion treatment is small, it being the reason of actor Perry’s death was ruled out. The medical examiner also noted that Perry’s last ketamine infusion therapy session happened more than a week before his death, which means by the time he had died, it must have worn off.

So, What Happened To Perry?

Though Perry’s last session was more than a week before, his post-mortem showed that his blood contained a high concentration of ketamine. He had died of the “acute effects” of ketamine.

If it was not his session, then how did he get ketamine?

Prosecutors alleged that his assistant gave him at least 27 shots of ketamine in four days before his death, reported BBC.

Perry has been open about his personal struggles and this is what the doctors and dealers used against him. Martin Estrada, the US attorney for California’s Central District told the BBC that people took advantage of his condition. They charged him 165 times more than what vials of ketamine cost.

Names that have come up include Dr Salvador Plasencia, drug dealers “Ketamine Queen” aka Jasveen Sangha and Eric Fleming, and Perry’s live-in assistant Kenneth Iwamasa.

Who Are These Names And What Did They Do?

Ketamine Queen or Sangha supplied drugs that led to Perry’s death. Her home was a “drug-selling emporium,” said Estrada. More than 80 vials of ketamine, and thousands of pills including methamphetamine, cocaine and Xanax were allegedly found in her house known as the “Sangha Stash House.”

Sangha is known to deal with high-end celebs and was a “major source of supply for ketamine to others as well as Perry,” said Estrada.

Dr Plasencia called Perry a “moron” while charging him $2,000 for vials that cost only $12. He sold Perry 20 vials of ketamine between September and October 2023, costing $55,000.

He was the one who taught Iwamasa, who had no medical knowledge to inject the drug. This is after he knew that “Perry’s ketamine addiction was spiralling out of control,” as per what the investigators told the BBC.

Another dealer Fleming was told by Sangha to “delete all our messages.” While Fleming pleaded guilty to conspiring to distribute drugs unlawfully, he also allegedly messaged Sangha: “Please call...Got more info and want to bounce ideas off you. I’m 90% sure everyone is protected. I never dealt with [Perry] only his assistant. So the assistant was the enabler.”

The court documents also revealed that he asked Sangha on whether the ketamine stays in your system or “is it immediately flushed out.”

Dr Pepper, Bots, Cans

The people who allegedly exploited Perry used coded language for ketamine and called it “Dr Pepper”, “bots”, or “cans.”

Selling overpriced drugs, taking advantage of Perry’s mental condition and falsifying medical records to make the drugs given to him look legitimate by Dr Plasencia is what took Perry’s life.

Iwamasa is said to have administered more than 20 shots of ketamine and three on the day Perry died. Whereas ketamine is only administered by a physician. Authorities also found that weeks before Perry’s death, Dr Plasencia allegedly bought 10 vials of ketamine and intended to sell to Perry.

He also injected Perry with a large dose, two days later. This caused him to “freeze up” and spiked his blood pressure.

When I Die, I Want Helping Others To Be The First Thing That’s Mentioned

Perry had always been open about his drug addictions, struggles with alcohol and his depression. He said that his openness would help others who are also struggling and wanted to be remembered by his quote which also is on the homepage of the Mattew Perry Foundation that helps others struggling with the disease of addiction: “When I die, I want helping others to be the first thing that’s mentioned.”

Five arrests have been made in the case so far.

Mongolia recently confirmed a suspected case of bubonic plague after a bacteriological laboratory delivered positive results. The National Center for Zoonotic Diseases confirmed on Friday that the case belongs to Mongolia's western Khovd province.

Mongolia Confirms First Human Case Of Bubonic Plague

According to reports, the patient contracted the infection after eating marmot meat during a visit to Ulaankhus soum in neighbouring Bayan-Ulgii province.

Mongolia's first confirmed case of bubonic plague has prompted officials to issue warnings against hunting and eating marmots, a known source of the deadly disease which is also considered a delicacy in the country.

The warnings also stated that individuals must avoid all forms of contact with the rodent, including handling their meat or internal organs. It also said avoid contact with sick or dead rodents as it could significantly increase the risk of infection.

The National Center for Zoonotic Diseases says 17 of Mongolia's 21 provinces are considered high risk regions for plague as the bacterium persists in wildlife.

Why Bubonic Plague Still Lurks In Mongolia?

The Black Death devastated Europe in the 14th century. Even today, a few countries still see cases of plague from time to time.

Humans typically get infected through flea bites from infected rodents, handling and close contact with infected animals and eating undercooked or raw marmot meat, which has been linked to several cases in Mongolia.

Mongolia has reported human plague cases to the World Health Organization since the 1980s. Sporadic infections continue to occur almost every year, particularly in the country's western and northern provinces.

The disease still lives centuries after it was eradicated because it is entrenched in wildlife rather than spreading continuously between people.

Humans are usually infected after being bitten by infected fleas or through hunting, skinning, or eating infected marmots.

Studies show that nearly 60% of Mongolia's reported plague cases since 1998 have been linked to close contact with infected marmots, highlighting why authorities repeatedly warn against hunting and consuming the animals.

Several infamous incidents related to the disease have sparked headlines in the last few years.

In 2019, a married couple died after eating raw marmot meat.

In 2020, a teenager also died after eating marmot meat, prompting temporary travel restrictions and heightened surveillance.

The latest confirmed human case in July 2026 follows the same familiar pattern.

Mongolia's challenge is not a new outbreak but an enduring zoonotic disease that resurfaces whenever humans come into contact with infected wildlife.

Where Else Does The Plague Still Exist?

Plague remains endemic in several parts of the world. According to the World Health Organization, the Democratic Republic of Congo, Madagascar, and Peru report the highest number of human cases globally. Since the 1990s, most reported cases have occurred in Africa.

Madagascar experiences seasonal plague almost every year, typically between September and April. The country drew international attention during a major 2017 outbreak, which caused more than 2,500 suspected, probable, and confirmed cases and over 200 deaths.

In the United States, plague is rare but has never disappeared. An average of about seven human cases are reported annually, mostly in rural parts of New Mexico, Arizona, Colorado, California, Oregon, and Nevada.

In 2026, Arizona reported its first human plague case in Apache County in more than a decade.

China has also reported occasional isolated human infections, particularly in Inner Mongolia.

The Ebola outbreak in the Democratic Republic of Congo (DRC) is expanding at an alarming pace, with confirmed infections nearing 3,000 and deaths exceeding 1,300, prompting the United Nations to warn that the virus is "spreading like wildfire" across eastern parts of the country.

The outbreak, caused by the rare Bundibugyo ebolavirus, has become the fastest-growing Ebola epidemic. Unlike Zaire strain, there are currently no approved vaccines or treatments specifically for Bundibugyo Ebola, making containment and management more challenging.

UN Says DRC Outbreak Is Spreading "Like Wildfire"

UN humanitarian officials have described the outbreak as one of the most severe public health emergencies. "The outbreak is spreading like wildfire," UN officials warned recently, highlighting that conflict, population displacement and attacks on healthcare facilities are preventing rapid containment efforts.

The World Health Organization (WHO) has repeatedly warned that the outbreak is becoming increasingly difficult to control.

According to WHO, a bunch of new infections cannot be linked to known transmission chains, indicating that the virus is spreading silently within communities.

Contact tracing remains inadequate to interrupt transmission, while insecurity and misinformation continue to hamper response efforts.

Health workers have also demonstrated strikes in some areas over unpaid dues, further disrupting patient care and containment efforts.

WHO has stressed that the global public health risk remains low, as Ebola spreads only through direct contact with the bodily fluids of infected individuals. However, the regional risk remains high because of active movement across borders.

Armed conflict in eastern DRC has limited access to affected communities, while attacks on health facilities, shortages of medical supplies, delayed laboratory testing and public distrust have slowed efforts to isolate patients, trace contacts, and contain the outbreak.

Hope Emerges As First Human Receives Experimental Bundibugyo Ebola Vaccine

Amid the worsening outbreak, researchers have reached an important scientific milestone in vaccination. The first human volunteer has received an experimental vaccine targeting the Bundibugyo strain of Ebola, marking the world's first Phase I clinical trial.

The study, led by the University of Oxford, will evaluate the vaccine's safety by studying its ability to trigger an immune response in 50 healthy adults.

The vaccine, known as ChAdOx1 BDBV, uses the same viral vector platform that was employed for the Oxford-AstraZeneca COVID-19 vaccine. Professor Katrina Pollock, chief investigator at the Oxford Vaccine Group, described the launch as "an important milestone" in the effort to develop protection against a virus for which no licensed vaccine currently exists.

Africa CDC Director-General Dr Jean Kaseya also welcomed the development, noting that although early-stage trials will not immediately help affected communities battle the current outbreak, they are critical for building better tools against future epidemics.

WHO notes that currently approved Ebola vaccines, including Ervebo, are designed to protect against the Zaire ebolavirus, not the Bundibugyo strain responsible for the ongoing outbreak. Researchers are also in the process to determine whether existing vaccines may offer partial cross-protection while Bundibugyo-specific vaccines continue to be developed.

Alongside vaccine research, WHO and international partners have launched clinical trials in the DRC to evaluate experimental therapies, including the monoclonal antibody MBP134 and antiviral drug remdesivir, in patients infected with the Bundibugyo virus. Researchers hope these studies will identify effective treatment options for future outbreaks.

A Florida man has filed a lawsuit against OpenAI and its CEO Sam Altman, alleging that medical advice provided by ChatGPT nearly cost him his life after the chatbot repeatedly discouraged him from seeking medical care.

Scott Winters, a former pastor, filed the lawsuit in San Francisco County Superior Court, claiming ChatGPT repeatedly advised him against seeking medical help as he experienced symptoms leading up to a near-fatal pulmonary embolism—a sudden and dangerous blockage in an artery in the lungs.

"ChatGPT-4o frequently opined on and evaluated Scott's physical condition, conveying the authority and confidence of a medical professional rendering a clinical assessment and treatment recommendation, despite not having the qualifications to do so," the lawsuit states.

Winters' lawyers further allege that the platform "repeatedly and insistently misdiagnosed" him while drawing on previous discussions about religion to reassure him that he would recover.

What Does The Lawsuit Allege?

According to the lawsuit, Winters became a regular ChatGPT user and gradually came to rely on the chatbot for medical advice, resisting repeated efforts by family members and friends to persuade him to visit a hospital.

Weeks before becoming critically ill, he consulted ChatGPT about recurring dizzy spells and "bouts of blood pressure instability."

The lawsuit claims that in one response, ChatGPT advised Winters to remain in the recliner chair to which he had become "mainly confined to" because of his worsening health.

Court documents state that Winters later suffered a "massive pulmonary embolism due to multiple blood clots in both of his lungs that brought him to the brink of death, one that his doctors stated was likely brought on because of his immobility."

Winters is seeking financial damages and is asking the court to require OpenAI to implement "reasonable safeguards that protect other users from harm."

ChatGPT Not Intended For Medical Care

Earlier this year, OpenAI launched a new ChatGPT Health feature in the US that can analyze users' medical records to provide more personalised responses, although campaigners have raised privacy concerns.

At the time, OpenAI said more than 230 million people ask ChatGPT questions about their health and wellbeing every week. In a blog post, the company said ChatGPT Health offers "enhanced privacy to protect sensitive data."

"ChatGPT is not a doctor and should never be used as a substitute for medical care, diagnosis or treatment," OpenAI spokesperson Drew Pusateri told CBS News, reacting to allegations.

He added: "AI can make that experience better by helping them find clearer answers, organize their questions and prepare for conversations with medical professionals."

ChatGPT's terms of use state that users should not treat the chatbot as a "sole source of truth," particularly for decisions that could "have a legal or material impact on that person, such as making credit, educational, employment, housing, insurance, legal, medical, or other important decisions about them."

Other Health-Related Lawsuits

This is not the first lawsuit OpenAI has faced over users' health and safety.

In May, a Texas couple whose son died from an overdose after seeking information about drugs from ChatGPT sued OpenAI, alleging he would still be alive if the company had not "bypassed safety guards."
