Cannabis-induced psychosis is becoming increasingly common across the UK. With stronger strains easily available and a perception that weed is harmless, doctors are seeing worrying consequences for mental health.

What Exactly Is Psychosis?

Psychosis is not just a medical term; it describes a mental state where someone loses touch with reality. A person in a psychotic episode may hear voices, see things that are not there, or believe unusual ideas with unshakeable certainty. Everyday surroundings feel warped, thoughts become jumbled, and behaviour can change dramatically. These episodes can last days, weeks, or longer, and while many people recover, some continue to experience symptoms for years.

Psychosis is not a condition in itself but a symptom of underlying mental illnesses such as schizophrenia, bipolar disorder, or drug-induced disorders. And cannabis, once dismissed as a “soft” recreational drug, is increasingly proving to be a serious trigger.

Cannabis and Its Dark Side

The UK has no shortage of cannabis users. In the year to March 2024, about 2.3 million people reportedly admitted to using the drug. But while regular use has halved over the past two decades, psychiatrists are alarmed by a sharp rise in cannabis-induced psychosis cases. The problem is potent modern strains and the growing popularity of “skunk”.

Skunk is produced from unpollinated cannabis plants with naturally higher levels of THC, the psychoactive compound responsible for the drug’s “high”. Unlike traditional varieties, these turbocharged versions can push the brain into paranoia, hallucinations, and even long-term mental health conditions.

The Risk Behind the Smoke

According to reports, the public health problem is deepening. There has been a visible rise in the number of people needing intensive support for psychosis as a result of cannabis use. What begins with smoking a few ‘joints’ and feeling a bit paranoid can easily escalate.

The issue is compounded by the fact that cannabis is readily available online. High-strength weed can be bought and delivered with the same ease as ordering a takeaway. For some users, that ease leads them into dangerous territory. Over time, repeated exposure to potent cannabis does not just spark temporary paranoia; it can cement itself into a chronic psychotic state.

How Cannabis-Induced Psychosis Feels

For those caught in its grip, cannabis-induced psychosis can be terrifying. Hallucinations distort familiar environments, creating confusion and fear. Dissociation leaves people feeling detached from their own bodies or surroundings. Everyday interactions can feel hostile or threatening, and the person’s sense of what is real becomes fragile.

While these symptoms may fade once the drug wears off, for some they linger, leading to severe depression or even suicidal thoughts. Studies suggest cannabis can also trigger schizophrenia in vulnerable individuals, an illness characterised by recurring psychotic episodes, delusions, and long-term disability.

Why Skunk Is Different

You might wonder, why is today’s cannabis so much more risky? The answer lies in THC levels. Traditional cannabis varieties contained lower amounts of this psychoactive compound, and many also carried cannabidiol (CBD), a chemical thought to counteract some of THC’s mind-altering effects. Skunk, however, has been bred to maximise THC and reduce CBD.

This results in a product that is stronger, more destabilising, and far more likely to provoke psychosis. While occasional users may brush it off as a “bad trip”, for others, the effects can be life-altering.

A Growing Health Crisis

Despite the popular image of cannabis as a “chill” substance, psychiatrists are dealing with an entirely different reality. Hospitals and rehab centres across the UK are seeing more young people admitted with psychosis linked to cannabis. Over time, people can reach a psychotic state which would not go away, even if they stop smoking. They can become very depressed or suicidal.

The public health implications are significant. Not only do psychotic disorders put immense strain on the NHS, but they also derail lives, disrupting work, education, and relationships.

Rethinking “Harmless” Weed

The narrative around cannabis has long been tangled. To some, it is a natural plant, a stress reliever, even a medicine. But the reality is more complicated. Yes, cannabis contains compounds with therapeutic potential, but when engineered for potency and consumed regularly, it can become a gateway to enduring mental illness.

People need to know that today’s cannabis is not the same mellow joint their parents smoked in the 1970s. It is stronger, riskier, and capable of tipping vulnerable minds into frightening psychological territory.

Summers are approaching and what would be better than having your own clothes that keep you cool? Scientists at the University of Alabama at Birmingham in the United States are working on innovations and have also applied for a patent. The research team led by Dr Vinoy Thomas, who is a native of Valakam in Kottarakkara. The findings have been published in the journal of the American Chemical Society.

What Is The New Finding Of Self-Cooling Fabric?

The researchers did not create a brand-new cooling fabric. Instead, they introduced a technique that transforms regular textiles into heat-regulating materials. This is done using two processes: electrospinning and plasma surface modification.

The first technique allows boron nitride nanoparticles to be evenly spread across the surface of the fabric. The second method uses low-temperature plasma (LTP) treatment to embed silicon oxide nanoparticles into the stitching threads.

Both boron nitride and silicon oxide are known for their heat-resistant qualities. By combining these two methods, researchers have created a coating that significantly lowers heat. The nanoparticles act as an added protective layer on the fabric.

Testing showed that the coating remains effective even after five to eight washes and does not affect the fabric’s original properties. Although its performance gradually decreases with repeated washing, researchers suggest applying a double-layer surface coating to improve durability.

Commercial production is expected to start once the patent is approved. In experiments, the coated garments reduced an external temperature of 35°C by 15°C, lowering it to 20°C. According to the researchers, this technique can be applied to any type of fabric.

Unlike earlier studies that focused on inventing entirely new heat-resistant materials, this innovation modifies existing fabrics. The study states that this approach is more efficient and cost-effective than current technologies.

The research team also includes Dr Ranjith Rajanpillai, Dr Kannadasan Appavu, Dr Claudiu T Lungu, and Dr Sanjay K Behura from the Department of Mechanical and Materials Engineering.

Innovations For Sizzling Summers

In Japan, something similar happened when former Sony engineer Hiroshi Ichigaya came up with kuchofuku or "fan jackets". This garment has a built-in feature, powered by battery, which is a fan at the lower back. This helps the circulation of air and to evaporate sweat and cool workers. These jackets are commonly used by construction workers, delivery partners, and people working in factory to combat extreme heat.

The meningococcal B vaccine (4CMenB) is completely ineffective in preventing gonorrhea -- a sexually transmitted infection (STI) --, especially among high-risk groups like gay and bisexual men, according to the results of the world’s largest randomized control trial (RCT).

Gonorrhea is a common bacterial STI caused by the bacterium Neisseria gonorrheae, and is transmitted through unprotected sex.

Even as antimicrobial resistance in gonorrhea has increased rapidly in recent years, Australian researchers explored the efficacy of 4CMenB against the disease.

The large randomized, placebo-controlled trial involving 587 gay and bisexual men showed that the risk of gonorrhea incidence remains essentially the same even after vaccination.

“Across both arms, the gonorrhea incidence was virtually the same -- at around 48 per cent per year, indicating very clearly that the vaccine had no effect on preventing gonorrhea,” said Professor Kate Seib, from Griffith University, in Australia, who led the trial.

In light of the study, the researchers stressed the need to explore other options to combat gonorrhea, such as condoms and regular testing.

The 4CMenB Vaccine

While meningococcal disease (caused by Neisseria meningitidis) and gonorrhea (caused by Neisseria gonorrhoeae) are distinct infections, both are caused by Neisseria bacteria, which share 80-90 percent genetic material.

The bacterium N. meningitidis primarily causes meningitis and septicemia, and observational studies have shown that meningococcal B (MenB) vaccines such as the 4CMenB offer 33-40 percent cross-protection against gonorrhea.

However, the latest study, presented at the Conference on Retroviruses and Opportunistic Infections in Denver, US, found no protection against gonorrhea.

The study “provides strong evidence that the 4CMenB meningococcal vaccine is not effective at preventing gonorrhea in gay and bisexual men who are at high risk of contracting it,” Seib said.

According to the US National Institute of Health, the 4CMenB vaccine is a highly effective, protein-based vaccine designed to protect against invasive meningococcal disease (IMD) serogroup B.

Approved in over 50 countries, it offers 71-95 percent effectiveness in infants and 100 percent in adolescents.

What Is Gonorrhea

Gonorrhea is a common STI, and sexually active people of any age can get the disease and pass it on to partners, and even to their baby during childbirth.

Gonorrhea is the second most common STI caused by bacteria, just behind chlamydia.

As per data from the World Health Organization (WHO), in 2020, there were an estimated 82.4 million new infections among adults globally.

The NIH noted that nearly 1 million new gonorrhea infections occur in the United States every year. About half of these infections occur in people ages 15 to 24.

The symptoms of Gonorrhea in men include:

• White, yellow, or green discharge from the penis
• Pain or burning (possibly severe) when peeing
• Testicular pain and swollen testicles.

Notably, the condition also occurs in women, but up to 50 percent of them won’t experience symptoms. This increases the risk of spread to other partners.

• Common symptoms in women include:
• Unusual vaginal discharge (white or yellow).
• Pain in your lower abdomen or pelvis.
• Pain during sexual intercourse
• Pain when you pee
• Bleeding between periods

A new study suggests that drinking sugary drinks can increase anxiety, among other mental issues, in adolescents by 34 percent.

Sugary drinks are known to be more harmful due to their low fiber, protein, or fat, which typically slow down digestion in solid foods. This means liquid sugar gets into your bloodstream very quickly, causing a sudden jump in blood sugar and insulin levels.

Hyper-fast intake of such drinks can also make it hard for your liver to process the sugar, especially the fructose part. n large amounts, fructose turns into fat in your liver. This buildup of fat is linked to metabolic problems that lead to Type 2 diabetes.

Apart from this, a Bournemouth University, UK literature review analyzed people aged between ten and 19 who drank fizzy drinks, colas, sweetened fruit juices, sweetened milk drinks, energy drinks, and sweetened tea or coffee and found multiple links between the beverages and anxiety diagnosis.

The gut-brain axis — the connection between the brain and the gut — may help explain the link between sugary drinks and anxiety. But gut health is influenced by many factors, including diet, stress, and sleep, which are also linked to anxiety.

Overall, the study suggests that cutting back on sugary drinks could help support teenagers’ mental health. While many studies have looked at how reducing sugary drinks improves physical health, more research is needed to see if it also benefits mental health.

WHO Asks Countries To Tax Sugary Drinks

The World Health Organization is asking countries across the world to increase taxes on sugary drinks and alcohol to reduce cases of chronic conditions such as Type 2 diabetes, obesity, heart disease and fatty liver.

In a January 13 virtual conference, WHO Director-General Dr Tedros Adhanom Ghebreyesus said: "Health taxes have been shown to reduce consumption of these harmful products, helping to prevent disease and reduce the burden on health systems.

"At the same time, they generate an income stream that governments can use to invest in health, education and social protection."

According to a recent report on sugar-sweetened beverages taxes, at least 116 countries tax sugary drinks, including sodas or carbonated canned drinks, but other high-sugar products, such as 100 per cent fruit juices, sweetened milk drinks and ready-to-drink coffees and teas, escape taxation.

Additionally, another report on alcohol taxes shows that even though 167 countries levy taxes on liquor, wine and beer, alcohol has become more affordable or remained unchanged in price in most countries since 2022, as taxes do not get adjusted for inflation and income growth.

How To Cut Back On Sugary Drinks?

Sugary drinks can feel addictive. If you find yourself hooked, try to slowly reduce how much you drink, just like you would with alcohol or tobacco. It helps to plan ahead for when you usually crave a soda.

You can start by mixing plain sparkling water with an equal amount of fruit juice or soda. Then, week by week, slowly reduce the amount of the sugary drink until you're mostly just drinking sparkling water. If it helps, add a little lemon or lime juice for flavor.
