International Overdose Awareness Day 2026: Understanding and Preventing Overdose

Every year, on 31 August, communities across more than 40 countries come together to mark International Overdose Awareness Day (IOAD), the world’s largest campaign dedicated to ending overdose.

Led since 2012 by the Penington Institute, a public health non-profit, IOAD began as a single event and has since grown into a global day of action.

Its aims are to amplify the conversation around overdose, share evidence-based prevention strategies, and encourage everyone, individuals, families, professionals and policymakers alike, to play a part in reducing overdose deaths.

This year’s theme, 25 Years On. Still Needed, reflects a sobering truth: despite decades of awareness-raising, overdose continues to affect people from all walks of life. It is also a reminder that overdose is preventable, and that timely support, education, and evidence-based action can save lives.

Here, we look at why IOAD is still so important, how overdose happens, and the role that drug testing can play in supporting prevention.

Why is International Overdose Awareness Day important?

Despite 25 years of IOAD campaigning, overdose deaths in the UK continue to rise.

According to the latest figures from the Office for National Statistics (ONS), 5,565 drug-poisoning deaths were registered in England and Wales in 2024 alone: equivalent to 93.9 deaths per million people.

This marks the highest number ever recorded since data collection began in 1993

Some of the key findings from the 2024 data include:

• A growing opioid crisis: just under half of all drug-poisoning deaths registered in 2024 were confirmed to involve an opiate or opioid (47.1%, 2,621 deaths)
• A sharp rise in synthetic opioids: 195 deaths involved nitazenes, a class of synthetic opioids, almost four times higher than in 2023. Some nitazenes can be significantly more potent than heroin, and are increasingly appearing in counterfeit medications and other street drugs
• Cocaine deaths continue to climb: there were 1,279 deaths involving cocaine registered in 2024, 14.4% higher than the previous year, marking over a decade of consecutive annual increases
• Poly-drug use as a major factor: more than half of all drug-poisoning deaths involved more than one drug, highlighting the risks of combining substances, whether intentionally or unknowingly
• Regional disparities: the North East of England continues to have the highest rates of deaths relating to drug poisoning and drug misuse compared with any other English region

It’s also worth noting that these figures likely understate the true scale of the problem.

In 2024, 1,192 deaths (21.4%) registered in England and Wales had no drug type recorded on the death certificate, meaning the real number of substance-specific deaths may be considerably higher.

How does an overdose happen?

Understanding how an overdose occurs is an important part of prevention.

An overdose happens when a person has more of a drug, or a combination of drugs, in their body than it can safely process.

Every drug, including illegal, prescribed and over-the-counter drugs, has a threshold beyond which the body struggles to cope, causing vital functions such as breathing and heart rate to become dangerously suppressed or disrupted. This is what makes overdose potentially fatal.

A few important points to understand:

• Overdose isn’t limited to illegal drugs 
  Medication prescribed by a doctor, such as opioid painkillers or benzodiazepines, can cause an overdose if taken in higher doses than intended or combined with other substances, including alcohol

• Mixing substances increases risk 
  Poly-drug use – taking more than one substance at a time – is involved in most drug-poisoning deaths. Combining depressants such as opioids, benzodiazepines and alcohol is particularly dangerous, as their effects can compound one another

• Contamination is a growing concern 
  The illicit drug market is unregulated, meaning substances are often cut, mixed or substituted without the user’s knowledge. This has contributed to the sharp rise in nitazene-related deaths

• Overdose can be fatal or non-fatal 
  A non-fatal overdose can still cause serious, lasting harm, and often serves as a critical warning sign that support is urgently needed

Overdose prevention: how drug testing can help

Overdose is preventable, and prevention starts with awareness, honest conversations, and access to accurate information.

While no single intervention can eliminate risk entirely, understanding what substances are present in a person’s system can play a valuable role in identifying concerns early and supporting safer outcomes.
