How a drug that's killed dozens of Australians is bypassing border control
Nitazenes are dangerous synthetic opioids that carry a high risk of overdose, even in very small amounts.
At least 17 Australians have died from nitazenes since 2021.
The dangerous compound is being found in fake sleeping, anti-anxiety and pain medication pills. It is also being used in drugs like cocaine, MDMA and heroin.
But these potentially fatal drugs are evading border control, Australian Crime Intelligence Commission's (ACIC) Shane Neilson said.
Nitazenes are so strong that only a fraction of a gram can be lethal. This makes it easy to send them through the mail in parcels, and hard for border control to detect.
"The traditional serious and organised crime groups do not play a significant role, as the less sophisticated groups are bringing the drugs into the country," Mr Neilson said.
The Australian Federal Police said they intercepted eight nitazene imports at the Australian border between January 2024 and March 2025, with parcels coming from Canada, the US and Hong Kong.
Nitazenes are being mixed into drugs sold online and marketed as opiates and benzodiazepines.
Opiates provide pain relief, used legally as drugs like morphine, endone and tramadol. Benzodiazepines, also known as benzos, can reduce anxiety and aid sleep. Examples include Xanax and Valium.
Nitazenes have also been found in party drugs like MDMA (also known as ecstasy) and GHB.
"They've been identified in vape liquids, they're in tablet forms, powders, nasal sprays," ACIC's Amber Migus said.
They are easy to order from manufacturers off the internet and being so potent, a small amount can be ordered and added to a large quantity of drugs.
About three Australians die every day from an opioid-related overdose. Opiates are behind most unintentional drug deaths, followed by benzodiazepines.
The number of drug-induced deaths related to benzos doubled in the 20 years to 2022.
They are both addictive and people can develop a dependency on pharmaceutical drugs after being prescribed for legitimate reasons.
More people die from unintentional drug overdose than from road accidents, according to the Penington Institute.
Why would a drug dealer add such a dangerous compound like nitazenes to their supply, risking killing their customers?
"Drug dealers are very cynical people," Mr Neilson said.
He said evidence from the United States' opioid crisis suggests dealers might be adding nitazene to their gear to create more loyal customers.
Drug users are more dependent on the original drug, become addicted to the nitazene, and eventually dealers can sell the nitazene directly.
Australia's strict prescribing rules may be why we do not have an opioid crisis like the US, Ms Migus said.
"It means that prevention and preventative actions can work in relation to illicit drug markets," she said.
"And we're always going to be watchful in relation to synthetic opioids because potentially they're so dangerous."
While nitazenes are a growing concern for health and crime authorities, a 2021 federal government report said 70 per cent of fatal opioid overdoses in Australia involved prescribed drugs.
Health authorities encourage anyone taking an opiate legally or illegally to carry naxolone. In both nasal spray and injectable form, it reverses the effect of an opioid.
A deadly substance a thousand times stronger than heroin is bypassing customs, experts warn.

John Worsfold and Alicia Molik among sporting greats taking part in Big Freeze event for MND research
An Australian father in the fight of his life against motor neurone disease (MND) is raising funds in the hope doctors can one day find a cure. Jordan Early, from Perth, was diagnosed five months ago and the disease has already ravaged his body, stealing his strength and speech. But the 42-year-old is determined not to let it defeat him. 'MND is not incurable, it's underfunded,' he told 7NEWS. 'If we can raise the money to keep pushing forward, we'll solve this one day.' The father-of-three has set himself the goal of raising $100,000 for research. He is doing it through Jordan's Big Freeze fundraiser, with a group of sporting greats including John Worsfold, Alicia Molik, Andrew Embley and Daisy Pearce to head down a slide into a pool of icy water on Saturday at Claremont Oval. The sliding starts at 1.45pm, prior to the WAFL match between Claremont and Peel at 2.30pm. There will be special coverage on Channel 7. You can go online now to donate and help Jordan achieve his goal.

Almost half our young Australians are lonely
Loneliness is not a word often associated with young people. We tend to think of our youth as a time spent with family, friends and being engaged with school and work activities. Loneliness is an experience we may be more likely to associate with older people. In a new report looking at loneliness in young Australians, we found 43 per cent of people aged 15 to 25 feel lonely. That's more than two in five young people. While one in four felt lonely when asked, one in seven had felt lonely for at least two years — what we call persistent loneliness. There's more we should be doing in Australia to address loneliness among young people and more broadly. What else did we find? In this report, we analysed data from the Household, Income and Labour Dynamics in Australia survey from 2022 to 2023. This helped us understand what sort of factors increase the risk of loneliness among young people. We found having poor physical health and mental health can double (or more) the likelihood of persistent loneliness among young people. Life circumstances, as well as socioeconomic and behavioural factors, also play a role, as shown below. Worryingly, young people who report persistent loneliness are over seven times more likely to experience high or very high psychological distress compared to those who aren't lonely. But loneliness in young people should not be seen just as a mental health issue. Research shows it can have consequences for physical health too. For example, a study published in 2024 found loneliness is linked to early signs of vascular dysfunction (functional changes to the arteries) in adults as young as 22. Why does loneliness persist? As well as analysing data, we also interviewed young people aged 16 to 25 from diverse backgrounds about what helps them make healthy social connections, and what hinders them. One of the things they flagged was a need for safe community spaces. A male participant from metro New South Wales, aged between 22 and 25, said: 'After lectures, someone's hungry, you go to eat together.' 'We used to go to (a restaurant) after almost every lecture. 'Talk or discuss some things so it gave us that extra opportunity to mingle amongst each other and take that next step towards building a good friendship.' We found technology could both help and hinder social connections. A female from regional Victoria, aged 22 to 25, who identified as LGBTIQ+, told us: 'If you're in school or something like that and you don't really have … many people within your community to look to, it's really nice being able to connect with people and make those friends online.' On the flip side, a female participant from metropolitan Victoria, aged between 16 and 18, said: 'A lot of maybe like mean stuff or like bullying and stuff happens over the Internet.' 'There's a big group chat and like everyone's texting on it or something. 'And then a lot of the time, people will break off into a smaller chat … or they'll break off into one on one and be like, ohh, do you see what she said?' The high cost of living was also regarded as a hindrance to maintaining social connections. As a male aged 22 to 25 from metro NSW told us: 'You'll go on (a) drive (with friends) or whatever … but that is so like incredibly expensive.' 'Having to pay for your own car and like petrol and insurance and maintenance. 'Sometimes it's hard to … even like … sit down in peace and have a chat. 'All the cafés will close at 2pm and by the time everyone gets out of their jobs, you're having to go to a restaurant and (you're) spending $50.' So what can we do? Loneliness has long been treated as a personal issue, but it's increasingly clear we have to shift our approach to include community-wide and systemic solutions. The World Health Organization's Commission on Social Connection recently released a report pointing to loneliness as a public health, social, community and economic issue. In Australia, the economic burden of loneliness stands at A$2.7 billion each year for associated health-care costs, including GP and hospital visits. And there are additional costs including lower workforce productivity and educational outcomes that have yet to be accounted for. Some countries have already developed and implemented strategies to address loneliness. In 2023, Denmark, for example, commissioned the development of a national loneliness action plan led by a consortium of organisations. This was underpinned by an investment of around 21 million Danish kroner (roughly A$5 million) over 2023–25. Australia now stands at a crossroads. Australia needs a national loneliness strategy A national strategy underpinned by evidence and by lived experience is crucial to effectively address loneliness. This approach would: coordinate efforts across sectors: health, education, social services and business identify effective strategies that should be included in a comprehensive response, and the principles to guide their delivery in communities and other settings highlight sub-groups at risk of persistent loneliness who should be prioritised within population-wide strategies commit to the delivery of a national awareness campaign that can educate the public and reduce stigma around loneliness. With the right national strategy, we will be able to increase our capacity to help all Australians, not just young people, connect in meaningful ways.
