Deadly ‘Frankenstein’ party drugs have hit Australia – here’s what you need to know


Strong opioids are being mixed into drugs to create deadly substances in Australia. Here’s what to look out for.

A deadly synthetic drug posing as cocaine has reached Australia, killing one person and causing several hospitalisations in Sydney over the past week. 

Dubbed ‘Frankenstein opioids’, the drugs are comprised of a potent cocktail of substances but are being sold to unsuspecting buyers as cocaine and ketamine. Due to the combination of substances, people are unable to manage their dosage of the high-strength opioids, causing unsuspecting buyers to overdose.

Frankenstein opioids were first detected in the United States last year, causing deadly consequences in several states, according to the Centre of Diseases and Control

They are characterised by the combination of a drug, like cocaine, heroin, Xanax and oxycodone, a strong and highly addictive pain medication, along with a cheap, synthetic opioid.

Similar concoctions have been seen on the streets, but are often combined with heroin or fentanyl. However, according to the Daily Telegraph, these Frankenstein opioids are even stronger, and deemed “more dangerous than fentanyl, and up to 200 times more potent than morphine.” 

Reportedly, the drugs, which are part of the nitazene family, are cheaper to produce than fentanyl (a powerful synthetic opioid) or heroin, which makes them an easy and low-cost substitute when producing the drugs.

As such, higher volumes of the potent drugs are likely in circulation, posing a risk not just for those in NSW, but around the rest of the country. 

Late last week, NSW Health issued a warning for heroin overdoses, with NSW Poisons Information Centre Medical Director, Dr Darren Roberts, saying “We’ve seen heroin overdose among people using what they thought was cocaine. A heroin overdose could quickly result from snorting a single line.” 

Fentanyl and heroin has been found cut into drugs in Australia before, with a health warning issued in NSW in November of 2020. However if the new data is to be believed, then these Frankenstein opioids pose an even greater risk than heroin or fentanyl. 

“It’s important that people recognise the signs of an opioid overdose early and know how to respond,” Dr Roberts. “Opioids such as heroin can cause pin-point pupils, drowsiness, loss of consciousness, slowed breathing/snoring and skin turning blue/grey and can be life-threatening.” 

“One of the dangers of illicit drug supply is the strength and contents of the substance you are getting is unknown and can be inconsistent. In light of this detection, people who use cocaine should also consider carrying naloxone” – a drug that can temporarily reverse opioid overdose.

Similarly, NSW Health states that “People who have never or rarely used opioids are at highest risk of overdose from these substances,” as they won’t know what effects to expect from consumption, or when it’s time to call an ambulance. 

Risk of overdose is also increased by the use of other sedatives like alcohol, benzodiazepines, ketamine, GHB. 

According to the World Health Organisation (WHO), “Opioid use can lead to death due to the effects of opioids on the part of the brain which regulates breathing”. Opioid overdoses can be characterised by the following three signs and symptoms: 

  • Pinpoint pupils
  • Unconsciousness
  • Difficulties with breathing.

“Anyone who has taken a stimulant drug, such as cocaine, and is experiencing unexpected symptoms, such as drowsiness, should call Triple Zero (‘000’) immediately or seek urgent medical attention. Naloxone should be given immediately if available,” says NSW Health. “It does not require a prescription and is free for anyone at risk of opioid overdose in NSW.” 

While going to the hospital after taking drugs may be scary, the government body urges people to remember they won’t get in trouble for seeking medical care. 

“If you feel unwell, or if your friend feels unwell, do something about it.”

How to spot a narcissist across the dinner table


Identifying a narcissist early on is no doubt the key to protecting yourself against their damaging behaviour. Now, according to a new study, it might be possible to pick them out based on how they pick their plate. 

If you’ve spent more than a little time in the company of a textbook narcissist, you’re likely familiar with the personality traits they exude. Defined by their over-inflated sense of self-importance, entitlement, lack of empathy and desperate need to be admired, narcissists in their full, unbridled glory aren’t difficult to spot. 

Now, it’s important to note most people alter their nutritional choices depending on what kind of social setting they find themselves in. For example, you’re more likely to fix yourself a classic smorgasbord of girl dinner when you’re home alone in your sweats than if you’re spending the evening surrounded by others. 

In the case of narcissists, recent research suggests these conscious behavioural changes may be even more amplified. A series of three American studies published in Psychology & Marketing examines the choices made by sample groups of adults (each inclusive of individuals exhibiting narcissistic tendencies), linking distinct eating patterns to the infamous personality type.

Breaking down the three studies

The three studies were each centred around foods that boasted token health properties but were known to be harmful in high doses. Before being presented with the food items in question, the participants were all asked to complete a questionnaire that gave researchers an indication of how narcissistic each person was. 

In the first study, a sample of 644 adults was offered wine, a beverage that despite its high alcoholic content is also rich in health-promoting polyphenols. In the second study, another random selection of participants was offered chocolate, a classically unhealthy choice that is sometimes praised for its anti-oxidant properties. 

Lastly, participants in the third study were subject to a more hypothetical scenario, being asked to consider consuming durian (a relatively unfamiliar fruit to most people in the US) in both a social setting and at home alone. Before making their decision, the participants were made to read a short overview of the fruit’s health benefits and disadvantages, such as supporting heart health and high in natural sugars respectively. 

What researchers discovered

Narcissists are often associated with a skewed sense of judgement, possessing a unique approach to weighing risks and benefits. The studies were designed to highlight this association in the context of nutrition, with the results of each indeed supporting the notion that narcissistic individuals were more likely to drastically alter their eating habits depending on their social surroundings. 

For instance, in the first two studies where participants were offered wine and chocolate in a social setting, individuals who exhibited narcissistic tendencies often chose to consume more. They were found to lean heavily towards the perceived ‘health benefits’ that both foods offered, choosing to ignore the high alcohol and sugar content of each.  

Researchers found these results to be in line with ‘optimism bias’, a known personality association guided by the notion that narcissists misjudge their susceptibility to positive or negative events. In other words, a narcissist would choose to indulge in wine and chocolate due to the foods’ health-promoting polyphenols and anti-oxidant properties, likely believing they would in turn not be impacted by the high alcohol and sugar content. 

In the third study, exploring the difference between eating habits in isolation and in a group, the participants believed to portray narcissistic tendencies were found to focus on the fruit’s health-related drawbacks in a social setting, therefore opting to eat less. When left alone, researchers found the same individuals leaned more heavily into durian’s heart-health properties, consuming more of the fruit.

Does liking chocolate and wine make you a narcissist?

While the researchers uncovered a pattern between people’s narcissistic tendencies and their decisions to consume or avoid certain foods, indulging in a block of Cadbury and a glass of red at the end of the day is not indicative of any particular personality disorder. 

Narcissistic eating habits were not found to be defined by people’s affinity towards certain foods, but rather by their willingness to reverse their opinion based on their social setting, leaning heavily into health consciousness when surrounded by other people.   

In each of the three studies, participants who demonstrated narcissistic tendencies (based on the questionnaire) were more likely to overestimate the health benefits of both wine and chocolate in a social setting, and durian when alone.

YouTuber Andrew Boyd tried a billionaire biohacker’s program to look younger


Most people wouldn’t mind looking younger, but what if you could literally turn back the clock on your body at a cellular level? YouTuber Andrew Boyd tried exactly that for 75 days.

You might have heard about Bryan Johnson, the 46-year-old Silicon Valley biohacker who is spending $3 million a year trying to reverse the ageing process. You’ve possibly seen pictures of the milky-skinned multimillionaire strapped to various machines like a shaved guinea pig in his quest to be 18 again. 

You may have read about the team of 30 medics he employs to monitor the biological age of his brain, heart, teeth, skin, hair, bladder, rectum and genitals, and you’ve probably decided that, on balance, Johnson’s regime – which includes waking at 4.30am, eating all his meals before 11am, taking 111 pills a day and bathing in LED light – might not be one for you. 

Andrew Boyd, a 23-year-old YouTuber from Chattanooga, Tennessee, has put a budget version of Johnson’s reverse-ageing program to the test, following his diet and exercise plan for an impressive 75 days – and he was shocked by the results. 

Like what you see? Sign up to our bodyandsoul.com.au newsletter for more stories like this.

One of the most eyebrow-raising elements of Johnson’s regime? The transfusion of blood plasma he received from his 17-year-old son. Boyd didn’t go to that extreme. “I didn’t swap blood with anybody,” he says with a laugh. “Some of the things that Johnson does are a little bit fringe – on the border of what is known to be scientifically sound.” Indeed, Johnson has said that he won’t be swapping any more blood because there were “no benefits detected”.

Instead, for approximately two and a half months, Boyd homed in on Johnson’s highly regimented diet, exercise and sleep plan, which is called Blueprint. This restricted him to consuming 2250 calories per day in a five- or six-hour window, exercising for at least an hour every day and getting roughly nine hours of high-quality shut-eye every night.

“I lost so much weight, so fast,” says Boyd, who documented everything for his YouTube channel, Project Andrew, on which he puts different health regimes to the test. He had been making corporate films for wineries before jumping into Project Andrew full-time, and weighed about 86 kilograms when he started. Over the 75 days, he shed almost 13kg. “At one point, my face had changed so much that the facial recognition on my phone wouldn’t work.” 

Boyd insists he “felt great” on Johnson’s diet of veggie meals, ‘Green Giant’ algae shakes (the chief ingredients are water, chlorella powder and collagen peptides), vitamin pills and supplements. “You have a lot of energy. My emotions didn’t seem to fluctuate as much throughout the day and I felt like I had clearer thought processes. There was never any time when I felt tired or full because of food.” His blood glucose levels, which he measured with a monitor on his arm, “were incredibly stable”. 

He did his weekly grocery shop at Aldi and ordered everything else in bulk online, spending about $170 a week on food and supplements. Johnson’s three meals a day included the ‘Super Veggie’, a cauliflower, broccoli, mushroom, ginger and black lentil dish, the ‘Nutty Pudding’, a berry and nut blend, and then one other veggie meal. Boyd took only a fraction of the 111 supplements on Johnson’s daily menu. 

And being half Johnson’s (chronological) age, he decided not to take testosterone, which Johnson himself supplements via patches. “I was worried that it would lower my natural levels. I think if I was above 40 years old, I probably would’ve considered taking it.”

Still, he lost weight so quickly that his testosterone nosedived – taking his libido with it. While obesity and excess belly fat are known for decreasing male testosterone levels, rapid weight loss can do the same. “My sex drive decreased – a lot,” he says. And his relationship suffered in more ways than one. “It was pretty difficult for my girlfriend. If we were going to a restaurant, I’d just hang out and sip water. The protocol sort of isolates you from people. Then my sleep schedule was really strict and regimented. And so we ended up spending less and less time together throughout the 75 days,” adds Boyd.

Improved sleep was what he thinks he benefited from most. “I’d try to get into bed around 8.30pm and spend nine hours in there, usually getting about eight and a half hours of sleep a night. It was the best sleep I’ve had in my life,” he says. “Before, I’d probably get about seven hours a night. Now, I feel better in the gym, I feel better when I’m running and I feel better when I’m working or writing.”

Boyd woke up at 5.30 or 6am. “You want to get exposure to a bright light, ideally sunlight, as soon as you can. Then, from about 7pm, I was limiting exposure to screens and blue light – I used those blue-light-blocking glasses,” he says. He measured his sleep patterns using a wrist device, specifically a Whoop 4.0 tracker. For a short time he took melatonin, a hormone that occurs naturally in the body and helps control how and when we sleep. It’s sometimes prescribed to people suffering insomnia, but only for short-term use.

“But before you blindly hop into taking something like this, you should definitely talk to your doctor,” warns Boyd, who stopped taking melatonin because it was causing him to have “crazy dreams”. Instead, he switched to a trio of sleep supplements – magnesium threonate, L-theanine and apigenin – which resulted in “significant improvements in my deep sleep, slow-wave sleep and REM”.

Not so challenging for Boyd, who was an avid soccer player when he was younger, were Johnson’s workouts. “He does some intense work on the cardio side, but he’s not lifting very heavy weights. Most of the exercises are fairly light and the idea is to flex and stretch every muscle in your body.” Boyd also did ‘Zone 2’ training – which involves not letting your heart rate go above a certain number of beats per minute – and his resting heart rate dropped from the low 60s to the low 50s.

After 75 days, says Boyd, his biological age was 19.2 – according to a blood biomarker analyser called InsideTracker – while his chronological age was 23.7. “It’s interesting,” he says, “but I don’t put a lot of weight behind this, because this biological snapshot is based on a really narrow window of time.” Meanwhile, Johnson, who has many more tools and lab tests at his disposal, has said his own heart’s biological age is 37, while he has the lung capacity of an 18-year-old.

So what did Boyd learn? “Bryan’s regime works really well for him. But if you don’t share the exact same goals – say, you want to run a marathon or lift more weight – then his diet isn’t for you. For me, doing it as an experiment was great. But it’s not how I’d like to live the rest of my life.” He values travel, eating out, his girlfriend and his mojo too much.

How breast milk could be key for early-stage breast cancer detection


A game-changing discovery of tumour DNA within breast milk is set to redefine how health professionals screen for the disease, promoting more accurate and life-saving diagnoses for women everywhere. 

Breast milk has long been championed for its ability to promote healthy development and boost immunity for a growing newborn. Now, it seems the natural liquid may be packing another lifesaving benefit. 

A recently published study has revealed the presence of tumour DNA circulating in breast milk. The discovery is set to alter the course of breast cancer screening and treatment for pregnant and postpartum women, some of the most vulnerable to breast cancer mortality rates. 

According to Christina Saura, PhD, and head of the team responsible for the groundbreaking research at the Vall d’Hebron Institute of Oncology (VHIO) in Spain, pregnant and postpartum women often tend to receive their cancer diagnoses in advanced stages.  

“It is typically assumed that the physiological changes in the breasts during gestation and lactation, which are considered to be normal, may hide a developing tumour, explains Saura. “The fact is that postpartum breast cancer, understood to be the ten years after delivery, accounts for 40 per cent to 45 per cent of breast cancer cases diagnosed before age 45.“

With such sombre statistics, researchers across the globe have been tirelessly working to uncover more effective and accessible methods for early detection. The latest discovery could now see women receiving an early diagnosis based on a simple liquid biopsy of their breast milk.

A surprise discovery 

According to Saura, the idea to test breast milk for any detection of breast cancer came from one of the institute’s patients, a woman diagnosed during her third pregnancy. Paranoid her tumour may have been transmitted to her second child before she was unaware of her diagnosis, she asked her doctors to test a sample of her breast milk she had kept stored in a freezer.  

“Though we knew that breast cancer is not transmitted through breast milk, we decided to test the sample and look for markers that could help our research,” explains Saura, on the institute’s subsequent discovery of DNA with the same mutation that was present in her tumour. 

With the milk sample having been stored in the freezer for more than a year, Saura and her team realised the potential breast milk had in offering a more accurate, early-stage detection method than other current screening techniques.

The subsequent research

The VHIO research team used two different techniques to analyse both breast milk and blood samples: next-generation sequencing and droplet digital polymerase chain reaction. Ana Vivancos, PhD and another author of the study, explains both methods confirmed the presence of ctDNA in breast milk, shining a light on the liquid’s association with earlier and more accurate detection. 

„We were able to detect tumour mutations in milk samples from 13 of the 15 patients with breast cancer who were tested, while circulating tumour DNA was detected in only one of all the blood samples that were collected at the same time,“ says Vivancos. 

Using a genomic panel calibrated to detect the genes that are most frequently mutated in breast cancer in women under the age of 45, the team found their breast milk screening model extremely effective in identifying early-stage tumours.  

„In practice, the panel design allows us to detect mutations in more than 95 per cent of breast cancer cases in women under 45 years old. Therefore, using this panel for early detection of this type of tumour during lactation should contribute to addressing a medical need that, until today, has gone unmet,“ explains Vivancos.

Could this test revolutionise breast cancer screening?

Given no screening techniques currently offer pregnant women an opportunity for early detection, this groundbreaking research could significantly increase the survival rate for women diagnosed with breast cancer during pregnancy, „That’s exactly the goal of this research: to screen for breast cancer in women who have just given birth,” Saura says. 

Unlike existing screening methods, this breast milk biopsy is non-invasive and painless, only requiring a milk sample from women after birth. So far, the method has also proven to be significantly more accurate than similar techniques involving blood samples. 

„We have seen that breast milk liquid biopsy was positive for the presence of circulating tumour DNA in 87 per cent of cases, whereas blood only revealed the presence of this marker in 8 per cent of cases,” says Saura. “This difference indicates that breast milk is a biofluid that is in more direct contact with tumour cells and therefore will be more informative in earlier stages.“

With further funding and research, the team at VHIO hope breast milk liquid biopsy will soon become a widely accepted screening method around the world for women of childbearing age.
