“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.

GLP-1 medications, widely prescribed for diabetes and weight loss, may also be associated with a lower risk of serious complications after surgery, a new study suggests.

The study, involving more than 2 million adults undergoing surgery, found that people taking GLP-1 medications had lower rates of major cardiovascular complications and postoperative infections than those not taking the drugs. Researchers from the University of Texas Health Houston presented the findings at the Anesthesiology 2026 annual meeting.

"GLP-1 medications have become part of everyday care for many people with diabetes or obesity, but physicians still need more evidence about how these drugs affect patients around the time of surgery," said lead author Josephine Tolan, an anesthesiologist at the Center for Outcomes Research, Department of Anesthesiology, Critical Care and Pain Medicine, McGovern Medical School at UTHealth Houston.

Tolan added that although the results are encouraging, more research is needed to determine if the medications themselves are driving these benefits and how best to manage them before and after surgery.

What Are The Key Findings

Researchers analyzed data from the Epic Cosmos database, a de-identified electronic health record database covering more than 1,700 hospitals and 40,000 clinics.

The study included US adults aged 18 and older who underwent elective surgeries lasting more than 60 minutes and stayed in the hospital for at least 24 hours after surgery between January 2016 and December 2024. Of the 2,028,601 patients included, 145,610, or about 7%, were taking GLP-1 medications.

After matching GLP-1 users with similar patients who were not taking the drugs, researchers found that GLP-1 use was associated with:

• 11% lower odds of major cardiovascular complications, including heart attack, heart injury, stroke or death.
• 8% lower odds of postoperative infections, including surgical site infections, urinary tract infections, pneumonia and sepsis.

Previous research has shown that GLP-1 medications can lower the risk of cardiovascular problems in some patients. However, their effects during and after surgery remain less clear.

Surgery places stress on the body, can trigger inflammation and may cause changes in blood pressure, blood sugar and circulation, potentially increasing the risk of cardiovascular complications and infections, the researchers explained.

Further, they suggest that GLP-1 medications may be associated with fewer cardiovascular complications because they support weight loss, improve blood pressure and blood sugar control, reduce inflammation and may protect heart muscle during periods of stress.

These medications may also help reduce infection risk by improving blood sugar control. High blood sugar can weaken the body's immune response, making it harder to fight infections.

GLP-1 Drugs And Cardiovascular Health

Research has found that people taking GLP-1 medications to treat diabetes, overweight or obesity have fewer major cardiovascular events, like heart attack or stroke, compared to people not taking GLP-1 medications.

In fact, the American College of Cardiology now recommends GLP-1 drugs as a way to reduce cardiovascular disease risk through weight loss.

When weight decreases, so does blood pressure, inflammation, LDL (bad) cholesterol and triglycerides, and protective factors like good (HDL) cholesterol increase. In other words, overweight or obese individuals who are prescribed a GLP-1 for weight loss may experience positive changes to their heart health, especially if they are at risk of heart disease.

Smokeless tobacco accounted for 57.3% of mouth cancers among men in India, while tobacco in any form estimated to be at least 73.4% of mouth cancers among women, according to a new study published in the Indian Journal of Medical Research.

The study, Head and Neck Cancer Burden Attributable to Tobacco Use in India: National and Region-wise Estimates, sheds light on the differences in tobacco-related cancer risks by sex, cancer site and region. The findings also bring attention to the role of smokeless tobacco products and their contribution to head and neck cancer burden in India.

The researchers estimated that eliminating tobacco exposure could prevent a bulk proportion of these cancers.

Researchers studied records of 11,285 patients diagnosed with head and neck cancers and 7,154 people with non-cancerous conditions who visited the Regional Cancer Centre in Thiruvananthapuram, Kerala, India between 2019 and 2024.

Among men, smokeless tobacco accounted for 61.8% of lip cancers, 30.7% of tongue cancers and 57.3% of mouth cancers.

On the other hand, almost 40.2% of cancers of the base of the tongue, tonsils and oropharynx, 45.7% of hypopharyngeal cancers and 38.4% of laryngeal cancers were attributed to smoking.

The authors highlighted how smoking and smokeless tobacco expose oral tissues to carcinogens. The authors wrote, “This may be because smokeless tobacco directly contacts the oral cavity, causing prolonged exposure of the tongue to carcinogens, whereas smoking produces more diffuse and less concentrated exposure.”

The study also found that 55.3% of men with mouth cancer used smokeless tobacco, compared to 17.5% of men in the comparison group. Among men diagnosed with hypopharyngeal cancer, 85% smoked.

Among women, smokeless tobacco accounted for around 68.8% of lip cancers and 68% of mouth cancers. Smoking accounted for 41% of oropharyngeal cancers and 34% of hypopharyngeal cancers.

The researchers estimated that the odds of mouth cancer among women who used smokeless tobacco were 17.6 times those among non-users. Among men, the corresponding odds ratio was 5.5.

Tobacco Cancer Risks Across States

The study also shows differences in tobacco-related cancer risks between states. Among men, the estimated proportion of mouth cancers due to smokeless tobacco was 71% in Jharkhand and 70.3% in Odisha.

In southern India, the estimates were 50.2% in Karnataka, 35.1% in Tamil Nadu, 33.9% in Telangana, 25.6% in Andhra Pradesh and 25.1% in Kerala.

Among women, the estimated proportion of mouth cancers due to smokeless tobacco exceeded 80% in Chhattisgarh, Odisha and several Northeastern states. In Tripura, it was around 90.4%.

The authors said that these differences could be due to regional variations in tobacco consumption and the products used.

However, the study used cancer risk estimates derived from hospital-based data in Kerala and applied them nationally because state-specific risk estimates were unavailable.

The authors addressed this limitation, stating, “In this study, due to limited State-specific data, cancer risk from tobacco exposures was assumed uniform nationwide.”

The researchers stressed the need for prevention by improving access to tobacco cessation services, especially in regions with high estimated burdens of tobacco-related cancers.

“The findings emphasise the need to strengthen tobacco cessation services, especially for high-risk men in regions with elevated population attributable fractions,” the authors wrote.

Health authorities in Australia's New South Wales have warned against unapproved peptide products after emergency department presentations linked to their use surged.

NSW Health recorded 1,180 peptide-related hospital presentations between July 2025 and September 2026, with about a quarter involving young people aged 16 to 24.

Retatrutide Accounts For 71% ER Visits

Retatrutide accounted for 71% of peptide-related emergency hospital admissions. Products described generically as “peptides” or by other names accounted for another 38%, while 8% involved combinations of products, News.com.au reported.

Peptides have gained popularity through social media, where influencers promote them for weight loss, muscle growth, injury recovery and anti-aging. However, unapproved products may have uncertain composition, quality and safety.

Monthly hospital emergency visits rose from five in July 2025 to 217 in September 2026, an increase of 4,240%. New South Wales Health Minister Ryan Park warned that unapproved substances posed health risks and placed additional pressure on public hospitals.

“Even when a product looks professional or comes in convincing packaging, that does not guarantee it is safe for use,” Park said.

Young people aged 16 to 24 accounted for about a quarter of presentations. Those aged 25 to 34 made up 32%, while 26% were aged 35 to 44. Men accounted for 51% of cases.

Health Risks Of Using Unapproved Peptides

Patients presenting to emergency departments after adverse reactions reported symptoms including

• abdominal pain,
• nausea,
• vomiting,
• chest pain,
• anaphylaxis
• allergic reactions.

Australia's Therapeutic Goods Administration (TGA) approves some peptide-based products, but many promoted online are not approved and may be unlawful to import, supply or advertise. These include BPC-157, GHK-Cu, TB-500, retatrutide and CJC-1295.

NSW Health Chief Health Officer Dr. Kerry Chant cautioned that products sold under the same label could vary in composition and strength.

“A professional looking website, a label, purity claim, reviews, or influencer endorsement is not proof of what is inside the product,” Chant said.

She urged people to consult their general practitioner about potential risks and safer, evidence-based alternatives.

What Is Retatrutide, And What Are The Risks?

Retatrutide is an investigational obesity drug developed by Eli Lilly. It targets three hormone receptors involved in appetite, blood sugar and energy balance: GIP, GLP-1 and glucagon.

In a Phase 2 trial published in the New England Journal of Medicine, participants receiving the highest dose lost an average of 24.2% of their body weight over 48 weeks. A Phase 3 trial published in The Lancet reported nearly 21% average weight loss among participants with type 2 diabetes and obesity.

Despite these results, retatrutide remains investigational and is not yet FDA-approved.

There have been several unbranded, generic copies of the Retatrutide chemical sequence manufactured by unregulated chemical labs and sold online. It may not have verified composition, quality or strength.

The drug has been dubbed the “Godzilla” of weight-loss jabs. A recent report by the Daily Mail showed 129 symptoms associated with its use, including skin-burning sensations, panic attacks, a racing heartbeat and depression.

Professor Naveed Sattar, professor of cardiometabolic medicine at the University of Glasgow, warned against purchasing unlicensed weight-loss products online. “I would urge people to avoid buying unlicensed weight-loss products online,” he said, according to Daily Mail. “There is no certainty about what these products contain, and without proper regulatory oversight there is a risk of adverse effects.”
