“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.

The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has introduced new measures to improve how the risks of suicidal thoughts and behaviors and persistent sexual dysfunction are communicated to people taking antidepressants.

Following a review involving patients and their families, the MHRA will introduce a boxed warning in patient information leaflets (PILs), a patient safety card, and an additional safety leaflet. The term “post-SSRI sexual dysfunction” (PSSD) will also be added to the leaflets for certain antidepressants.

“Patients need clear and accessible information about the benefits and risks of medicines so they can make informed decisions,” Dr. Alison Cave, MHRA chief safety officer, said.

She said the changes would support informed discussions among patients, caregivers, and healthcare professionals. Dr. Cave added that antidepressants can effectively treat depression when used appropriately and under clinical supervision. Patients should not stop taking these medicines without first consulting their healthcare professional.

Patient information leaflets will feature a boxed warning directing readers to information about suicidal thoughts and behaviors, making the guidance easier to find.

A patient safety card is expected to accompany medicine packaging, reinforcing key safety messages and explaining when and how to seek support.

For certain antidepressants, updated leaflets will include information on PSSD, highlighting the possibility that sexual dysfunction may persist after treatment ends.

The MHRA is also developing an additional safety leaflet with the wider healthcare system. Expected in 2027, it will explain the benefits and risks of antidepressant treatment to support informed decisions. It will be given to patients at their first appointment discussing antidepressants and to those already receiving treatment.

Concerns Over SSRI Safety Warnings

The MHRA has received four prevention of future deaths reports since 2020 concerning antidepressant prescribing and safety information. One followed the 2024 death by suicide of Thomas Kingston, husband of Lady Gabriella Kingston, at age 45.

An inquest heard that Kingston had been prescribed sertraline and later switched to citalopram after reporting that his medication was not helping. Both are selective serotonin reuptake inhibitors (SSRIs). He had also received the sleeping tablet zopiclone for sleep difficulties and had stopped taking his medication before his death.

Gloucestershire senior coroner Katy Skerrett questioned whether patients were adequately informed about the suicide risks associated with SSRIs. Kingston’s parents called for clearer communication of potential side effects to patients and their families.

What Should Healthcare Professionals Do?

The MHRA advises healthcare professionals to:

• Discuss the risk of suicidal thoughts and behaviors when starting antidepressants, changing doses, and during subsequent reviews.
• Explain that some antidepressants can cause sexual dysfunction that may continue after treatment stops.
• Follow relevant National Institute for Health and Care Excellence (NICE) guidance and monitor patients regularly after treatment begins.
• Provide the additional safety leaflet when it becomes available in 2027.
• Report suspected adverse reactions through the MHRA’s Yellow Card scheme.

What Should Patients Taking Antidepressants Know?

Patients experiencing new or worsening suicidal thoughts should seek urgent medical attention, particularly when starting treatment or changing their dose. In the UK, they can contact NHS 111, their local mental health crisis team, Samaritans on 116 123, or the SHOUT text service at 85258.

Anyone concerned about sexual dysfunction during or after antidepressant treatment should contact their healthcare professional.

The MHRA said these are not new risks associated with the medicines. Patients should read the information supplied with their medication and consult their healthcare professional before stopping treatment.

Lead poisoning is a widespread but preventable health threat that contributes to more than 3.5 million deaths globally each year and puts hundreds of millions of children at risk, the World Health Organization (WHO) said.

Marking International Lead Poisoning Prevention Week 2026, WHO urged countries to accelerate prevention efforts amid growing global momentum to tackle lead exposure.

Why Is Lead Dangerous for Children?

Children are particularly vulnerable to lead because their developing brains and nervous systems are highly susceptible to its toxic effects. Even low levels of exposure can cause irreversible harm, affecting learning, behavior and development.

“Lead poisoning should not be stealing children's potential in 2026,” said Bruce Gordon, Director a.i. of WHO’s Department of Environment, Climate Change, One Health and Migration.

“We know where many exposures come from and we know how to prevent them. Countries now need to move upstream, removing lead from products and environments before it reaches a child's bloodstream. WHO is working with governments and partners to help turn that evidence into action,” Gordon added.

How Does Lead Poisoning Occur?

There is no known safe level of lead exposure, WHO warned. Exposure can occur through paint, cookware, cosmetics, spices, informal recycling and industrial contamination, among other sources.

Lead affects multiple organs and can contribute to cardiovascular and kidney disease in adults. In children, exposure can cause lasting damage to brain function and development. Its effects may go undetected until significant harm has occurred.

Lead is distributed to the brain, liver, kidney and bones. It is stored in the teeth and bones, where it can accumulate over time. Human exposure is assessed through the measurement of lead in blood.

WHO Plans Global Action On Lead Exposure

Fewer than half of countries had confirmed legally binding controls on lead paint, according to WHO's latest published global assessment.

This year's International Lead Poisoning Prevention Week theme, “From Detection to Prevention,” highlights the need for stronger policies, better enforcement of safety standards and greater public awareness to eliminate lead hazards at their source.

WHO Member States have recognized lead exposure as a pressing public health concern and mandated the development of a Global Action Plan on Lead Mitigation, which will be presented to the World Health Assembly in 2027.

The WHO will also launch the PREVENT Technical Package on Lead Poisoning Prevention in 2027. It will provide practical guidance to help countries identify major exposure sources, prioritize interventions, strengthen regulations and track progress.

Last year, WHO joined partners in the Lead Poisoning Prevention Initiative to strengthen laboratory capacity for blood lead testing, supporting the monitoring and early detection of exposure.

The initiative will provide technical support and build laboratory capacity in Brazil, five states in India, Nepal and six sub-Saharan African countries: Ethiopia, Ghana, Malawi, Rwanda, South Africa and the United Republic of Tanzania.

WHO Calls for Stronger Prevention Measures

Preventing lead exposure can also reduce health care costs, improve educational outcomes and support healthier, more productive societies.

The WHO urged countries to move beyond detecting lead exposure and adopt comprehensive prevention strategies such as:

• Eliminating lead hazards from products and environments.
• Strengthening regulations and enforcement.
• Improving monitoring and surveillance of lead exposure.
• Strengthening capacity to manage lead poisoning cases.
• Raising public awareness about exposure sources and prevention.
• Promoting safer industrial practices and waste management.
• Prioritizing children and other vulnerable populations.

Scottish swimmer Archie Goodburn has welcomed the UK government’s plans to review progress in brain cancer research after years of campaigning for better treatment and greater investment in research.

Goodburn, 25, revealed in 2024 that he had been diagnosed with three inoperable brain tumors. In August, he broke down during an interview on BBC Breakfast as he spoke about the challenges faced by patients with brain cancer and their families.

He appealed to the government to invest more in research, urging it to “give us a chance to fight for our lives.” His plea led to a meeting with Prime Minister Andy Burnham.

The government has now announced a new national brain cancer clinical lead and a review of progress in brain cancer research, with the aim of helping patients access treatments sooner, the BBC reported.

Goodburn thanked the prime minister, saying all three of his requests had been “promised to some extent,” although the details still needed to be worked out.

Burnham described Goodburn as an “inspiration to us all” and said he was “delighted” to welcome him to Downing Street.

“He has spoken passionately about the need for change on brain cancer, and he's right: progress hasn't been good enough, here or anywhere else. Families facing this disease can't afford to wait,” Burnham said.

According to the BBC, the review will be led by Professor Anthony Chalmers, chair of clinical oncology at the University of Glasgow. It will assess progress in brain cancer research since 2018 and identify “what is still holding progress back.”

The review will be followed by a national cancer plan aimed at getting new treatments “out of the lab and to patients faster,” Downing Street said.

The prime minister has also asked the Medicines and Healthcare products Regulatory Agency (MHRA) to complete its review of regulations for medicines used to treat rare conditions sooner.

Goodburn has urged the regulator to finish the review within two years rather than three, bringing forward potential changes that could help patients access new treatments sooner.

Scottish First Minister John Swinney, who also recently met Goodburn, highlighted the Scottish government's commitment to supporting more clinical trials.

“We are proud to support national leadership for brain cancer through the Scottish Adult Neuro-Oncology Network,” Swinney said.

The network brings together clinicians, patients and voluntary sector representatives to improve care for people with brain cancer across Scotland.

“We will give careful consideration to any further role which Scotland could play to give people living with brain cancer a faster route from research to treatment,” he added.

The Edinburgh-born swimmer sought medical tests after experiencing numbness and seizures while training for the 2024 Olympic trials. He was diagnosed with three large oligodendrogliomas, a rare type of tumor that can affect the brain and spinal cord.

He underwent chemotherapy and radiotherapy, but surgery to remove the tumors was not possible.

Despite his diagnosis, Goodburn competed at the 2026 Commonwealth Games in Glasgow, reaching the final of the 50-meter breaststroke but narrowly missing out on a medal.

Charity Brain Tumour Research has described brain tumors as the cancer most likely to kill people under 40 in the UK.

“One of my dreams is that we see a future where brain cancer isn't the biggest killer of patients under 40,” Goodburn said during the Commonwealth Games.
