International Overdose Awareness Day marks its 25th year on August 31, 2026, under the official theme “25 years on. Still needed.” The campaign is using the anniversary to focus on remembrance, overdose prevention, timely care and support.

The event began as a remembrance gathering in Melbourne, Australia, in 2001, and Penington Institute took the lead in 2012. Organizers now report more than 1,000 events in over 40 countries each year. Those campaign totals show reach, but they do not measure access to emergency care or overdose treatment.

Unresponsiveness or abnormal breathing requires emergency action

A person who cannot be awakened or is not breathing normally after possible drug use needs the local emergency medical service immediately. The International Federation of Red Cross and Red Crescent Societies (IFRC) identifies slow, absent, snoring or gurgling breathing as signs of suspected opioid overdose and calls for immediate cardiopulmonary resuscitation (CPR) and emergency-system activation. Emergency numbers and dispatcher protocols differ by country.

  1. Activate the local emergency medical system. The caller should state that the person is unresponsive or breathing abnormally and put the phone on speaker when safe to do so.
  2. Start CPR when the person is unresponsive and not breathing normally. IFRC guidance says CPR should begin immediately and continue until normal breathing or other signs of life return, or emergency personnel take over. A dispatcher can give instructions that match local practice.
  3. Use naloxone for suspected opioid overdose if it is available and locally permitted. The trained responder should follow the supplied product instructions, and administering it must not delay CPR.
  4. Keep monitoring breathing after the person responds. The World Health Organization (WHO) says bystander naloxone is an interim response rather than a replacement for comprehensive medical care. Responders should receive any known details about the substance, but identifying it must not delay care.

Naloxone reverses opioids, not every overdose

WHO describes naloxone as an opioid antidote that can reverse an opioid overdose when given in time and has virtually no effect in people who have not taken opioids. It is not a general antidote for sedatives, stimulants, alcohol or other poisons. An unknown or mixed exposure therefore still requires emergency assessment and support for breathing.

WHO's 2014 community guideline recommends that people likely to witness an opioid overdose receive naloxone and training in its use. The same guideline says responders should focus on the airway, assisted ventilation and naloxone, then observe breathing and consciousness after resuscitation. The IFRC's 2025 update places CPR ahead of searching for or administering naloxone when cardiac arrest is suspected.

WHO says naloxone remains limited in many countries, including in some ambulances and medical facilities, while other countries allow access without a prescription. Formulations, training requirements and legal rules are local. APPI News could not verify a public supply route or regulatory status in every country at the time of writing.

The global death estimate still carries a long reporting lag

WHO's fact sheet, published August 29, 2025, estimates that about 125,000 people died from opioid overdose worldwide in 2019. It also estimates that nonfatal opioid overdoses were several times more common. The date matters: the figure is not a 2026 count and cannot describe current risk in a particular country.

The limits are not confined to mortality data. The IFRC's 2025 review found 10 education studies on opioid-overdose response, all from the United States, Canada or the United Kingdom, and identified an evidence gap elsewhere. A global first-aid recommendation can set the sequence, but implementation still depends on each country's emergency system, laws and available products.

Risk rises after abstinence and with drug combinations

WHO lists resuming opioid use after an extended period of abstinence, using prescription opioids without medical supervision and combining opioids with alcohol or medicines that suppress breathing among overdose risk factors. Older age and concurrent lung, liver or mental health conditions are also on its list. These factors can inform a clinical assessment but cannot diagnose an overdose or identify a substance at the scene.

Emergency stabilization and longer-term treatment are separate decisions. WHO recommends evidence-based treatment options for opioid dependence, but services and medicine availability differ across countries. A local clinician or drug-treatment service must assess treatment; an emergency episode is not a basis for an improvised medication change.

Children need age-specific resuscitation instructions

The emergency threshold does not change for a child who cannot be awakened or is not breathing normally. IFRC notes that CPR recommendations differ between adults and children, so the child's age should be given to the dispatcher and age-appropriate instructions should be followed.

Pregnancy, chronic illness and regular medicines should also be reported during the emergency call because they can affect clinical assessment. People in these groups need case-specific directions from the dispatcher or treating clinician; general adult instructions cannot settle those differences.

Campaign reach does not remove local access gaps

The campaign says its annual events honor people who died, educate families and peers, and examine evidence-based prevention. Its 2026 theme connects those goals to 25 years of activity. The organizers' event and country counts have not been independently audited by APPI News.

The verified common sequence is narrower: recognize unresponsiveness or abnormal breathing, activate the local emergency system, start CPR when indicated and use naloxone for suspected opioid overdose when local rules allow. Naloxone access and emergency routes remain country-specific. APPI News could not verify either one for every market as of August 31, 2026.
