Authorities in New South Wales and Victoria are raising alarms about a disturbing rise in heroin overdoses among individuals who mistakenly believed they were using cocaine or methamphetamine. Reports indicate that this issue is not confined to these states and is becoming increasingly relevant across Australia. The implications are staggering, as heroin is notorious for causing life-threatening opioid overdoses, especially in those unfamiliar with its use.

Recent research has uncovered startling findings about accidental heroin consumption. A vital initiative by NSW Health is dedicated to swiftly addressing troubling trends in illicit and recreational drug use. This program involves collaboration among various government health entities, including hospitals, the NSW Poisons Information Centre, and forensic labs.

From our data analysis, we identified 34 instances of opioid overdoses linked to users who thought they were consuming stimulant drugs between January 2022 and June 2024. Among these, 19 individuals believed they were taking cocaine, while 15 thought they were using methamphetamine. Tragically, two fatalities were reported among this group.

In every instance where we specifically tested for it, heroin was identified as the opioid involved. Notably, 68% of these cases occurred in Sydney, and our analysis revealed that the frequency of such incidents is on the rise, with multiple cases surfacing each month recently.

In the United States, the dangerous trend of mixing stimulants with the potent opioid fentanyl has resulted in a catastrophic increase in overdose deaths. However, no evidence suggests fentanyl's presence in the Australian cases we've studied.

What Happens When You Accidentally Snort Heroin?

Cocaine and methamphetamine are stimulant drugs that lead to feelings of euphoria, increased energy, and confidence. In contrast, heroin acts as a sedative, relaxing the user and causing drowsiness. The opposing effects of these substances mean that someone who mistakenly consumes heroin, expecting a stimulant experience, can easily succumb to an overdose. For those unaccustomed to opioids, even a small dose—such as snorting a line—can be fatal.

Why Are These Mix-Ups Happening?

Drug users may unintentionally receive a different substance than they intended due to various reasons during production and distribution processes. Heroin often resembles cocaine or methamphetamine visually, which complicates efforts to identify drugs until after consumption.

What Can Be Done?

Preventing opioid-related deaths is possible, and government agencies, along with community organizations, are actively tackling this crisis through drug alerts and education initiatives. Users of illicit substances can mitigate risks by avoiding solitary drug use and designating a responsible individual in their group to seek help when necessary.

If someone appears unusually drowsy after drug use, it is critical to seek immediate assistance rather than dismissing it as a normal reaction. Initiate CPR if the person is unresponsive and call emergency services.

The Life-Saving Role of Naloxone

Naloxone, a vital medication that can reverse opioid overdoses, should be administered promptly if an individual exhibits overdose symptoms. It is available for free without a prescription through the national Take Home Naloxone program and can be ordered online or obtained through local pharmacies.

Authorities urge that naloxone be accessible for anyone who may encounter an opioid overdose scenario. Call 000 even after naloxone is given, as professional medical assistance is paramount.

Remember, if you observe unexpected overdoses or have concerns about drug usage, contact the Poisons Information Centre at 131 126 from anywhere in Australia. In emergencies, always dial 000. This alarming trend highlights the urgent need for public awareness and safety measures. Stay informed and stay safe!
