Concerns grow over workplace drug use
Amphetamine and opioid use is a major hazard and Dunedin is not immune to the risks.
The Drug Detection Agency (TDDA) says findings in its 2024 fourth quarter workplace drug and alcohol report indicate a rise in amphetamine-type substances and opioids compared with the same period in 2023.
The most prevalent substances detected nationally in TDDA testing included THC (Cannabis) at 59.1%, down from 63.8% in Q4 2023.
Amphetamine-type substances rose to 24.4% from 18.8% and opioids rose to 12.1% from 11.9%.
Drug Detection Agency chief executive Glenn Dobson said working under the influence of amphetamines was a major workplace hazard.
"These substances impair vision, cause dizziness, and adversely affect co-ordination, increasing the risk of serious accidents.
"In high-risk environments like construction, transport, and manufacturing, impairment can be the difference between a routine workday and a fatal incident."
Cannabis use in New Zealand has always been high but the rise in opioids was worrying because it suggested the country may be following a global trend.
"America has a huge problem with opioid abuse, and they have a lot of deaths."
"The opioid abuse brings the safety issues into the workplace as well."
Several factors could be driving the increase, including overprescribing painkillers such as Tramadol.
"Tramadol is obviously a synthetic opioid that is a very good painkiller, but also affects people's abilities to react in certain situations.
"So if you are operating machinery, if you are driving trucks, vehicles, it could affect your ability to do that in a safe manner."
Another contributor to the rise was the commercialisation of drugs.
"Drugs are very commodified these days, and they follow trends and fashions.
"We have seen synthetic opioids like fentanyl, for instance, in the States being put in other drugs to either give the drug user a different high or to give them an addiction so that they keep going back to that drug dealer."
A further driver is the growing influence of global gangs.
"We know that New Zealand is a popular market for global gangs because we pay more for drugs in New Zealand."
Massey University's 2024 New Zealand Drug Trends Survey found one in four frequent drug users reported having used a pharmaceutical non-medically in the past six months.
Non-medical use of ADHD medications is highest in Wellington, Otago and Auckland.
The survey links ADHD medication misuse to student populations and party drug culture.
"Dunedin has a large student population and the geography and population in any area is going to dictate some of the drug taking trends in that area."
Companies seeking a drug-safe workplace needed to adopt a robust, current drug and alcohol policy backed with training so everyone understood its purpose.
Frank conversations needed to be fostered to focus on getting workers home safely and fair testing programmes needed to run so risks identified could be managed openly and justly, Mr Dobson said.

New Zealand Adults Facing 'Hidden Epidemic' Of Undiagnosed Dyslexia And ADHD
Press Release – Truth About Dyslexia AUCKLAND, NZ – A growing number of New Zealanders in their 30s, 40s, and 50s are waking up to a confronting truth: they've been living with undiagnosed dyslexia and ADHD their entire lives, and it's been affecting far more than just their spelling or ability to concentrate. Stephen Martin, founder of Truth About Dyslexia and host of the podcast nearing 1,000,000 downloads globally, says it's time to stop viewing these diagnoses in isolation. 'Too many people are being handed ADHD as a diagnosis and told 'that's the answer', but underneath it, there's often undiagnosed dyslexia,' says Martin. 'Dyslexia isn't just a childhood reading issue. It lives in our self-esteem, our work habits, our relationships, and our mental health.' As Mental Health Awareness Month wraps up, Martin is urging Aotearoa to face what he calls 'the root issue hiding in plain sight.' 'You don't grow out of dyslexia or ADHD. You grow around it, masking it with perfectionism, people-pleasing, addiction, or burnout,' he explains. 'And it's exhausting. The system never gave us the right lens, so we internalised that we were broken.' Online searches for adult ADHD have surged in New Zealand over the past year, but dyslexia remains under-discussed, especially in adults. Martin believes that's a dangerous oversight, particularly for Māori and Pasifika communities where access to diagnosis was (and often still is) limited. He's calling on the government and mental health sector to: Acknowledge the deep overlap between mental health symptoms and undiagnosed neurodiversity. Raise awareness around adult dyslexia and its lifelong impact, especially in communities underrepresented in diagnosis data. Fund accessible adult screening for dyslexia and ADHD across all regions of New Zealand. Martin's podcast, Truth About Dyslexia, has become a global voice for adults navigating late diagnosis and reframing what it means to live with a neurodiverse brain. With his signature straight-talking Kiwi style, he pulls no punches about the trauma caused by decades of misunderstanding. 'Dyslexia and ADHD often travel together, but it's dyslexia that teaches you to hide your truth. And hiding comes at a cost. Until we treat the roots, not just the branches, people will keep falling through the cracks.' About Truth About Dyslexia Founded in 2019, Truth About Dyslexia is one of the most downloaded adult-focused dyslexia podcasts in the world. Hosted by New Zealander Stephen Martin, the show explores the messy, unspoken sides of neurodiversity, from addiction to anxiety to late diagnosis, all through a refreshingly human lens.

What's protein, why do we need it, and how do you get more?
Photo: 123RF Distinguished professor Paul Moughan from The Riddet Institute is an expert in all things protein related. The Riddet Institute is a Centre of Research Excellence (CoRE) focusing on fundamental and advanced food research. It's hosted by Massey University on the Palmerston North campus. Dr Moughan answers some questions from the Country Life team. Protein is a very important component for the human body. It's central to body function and therefore to nutrition. We get proteins from the foods we eat - we don't need protein itself but rather the amino acids that are the building blocks of protein. When we eat protein, it gets broken down to amino acids and it is those that are absorbed. There are nine essential amino acids. Some foods can supply all nine of those amino acids readily, while others might be deficient in one of those essential amino acids. Follow Country Life on Apple Podcasts , Spotify , iHeart or wherever you get your podcasts. The amount of protein we need depends on a persons age and weight. The average adult needs about 0.8 grams of protein per kilogram of body weight - so a person who weighs 80kg needs about 65g of protein per day. Again though it comes back to the quality of the protein and the amino acids you can get from it. From a lesser quality protein you might need more to get the same benefit. We also need more protein as we age - about 1.5g compared to 0.8g. Generally there's no such thing as too much protein for most people. Distinguished professor Paul Moughan from the Riddet Institute. Photo: Supplied There are major differences between proteins. Consumer information is pretty poor. Looking at the protein content on a product's label is a good starting point but it doesn't speak to the quality of the protein. As a general rule, animal-based proteins - so milk, dairy- based proteins, egg, meat, fish - are all very high quality. They have all the amino acids you need and they're highly digestible and highly available. Soyabean-based foods like tofu and tempeh are also high quality. Peas and beans tend to be high in protein but the quality is not always high. A lot of the vegetable-based proteins are less good quality so you would need to consume more of them. Pea and potato-based proteins can be good for vegan or vegetarian diets though. In the past it didn't matter too much because we generally consumed mixtures of proteins. Now there's a movement worldwide to go away from animal-based proteins more towards vegetable-based proteins and as we do that we need to be more careful. There have been studies of vegan and vegetarian diest which have found people were not meeting their total protein requirements in terms of quality. Protein quality is going to become more of an issue. When we look at future world food needs, because the world population is growing, it's also ageing, protein is going to become a major consideration. I personally think it shouldn't be vegetable or animal. It needs to be vegetable and animal. It may be very appropriate to move towards more vegetable-based foods but I think people who completely exclude animal-based foods may well be entering into the territory of nutritional inadequacy and problems with their diet. It's all about balance.
