Today’s illegal drug supply remains highly toxic and unpredictable. Substances are often mixed, and many overdoses involve combinations of depressants, stimulants, additional opioids, and other contaminants, making overdoses harder to predict and respond to. As a result, Canada’s drug toxicity crisis continues to affect individuals, families, communities, and members of the Defence Team.

International Overdose Awareness Day was Aug. 31, with trends showing substance-related harms remain significantly higher than pre-pandemic levels, despite encouraging signs of improvement in 2025.

Naloxone and overdose response

You do not need to know exactly what substance was used to respond to an overdose.

Naloxone is a safe, effective, and easy-to-use medication that can temporarily reverse the effects of an opioid overdose. If someone shows signs of poisoning or overdose, act quickly: call 911 and provide appropriate first aid and naloxone, if available. An overdose can be fatal; a rapid response can save a life.

Learn how to use naloxone in just a few minutes by watching this short video or by participating in training available in your area. Take-home naloxone kits are available through pharmacies without a prescription.

Taking action across the Defence Team

Naloxone is becoming more widely available, and awareness of mental health and substance use continues to grow. Across Canada, individuals, communities, and organizations are taking action to reduce substance-related harms and support those affected by substance use. One example is Captain Aoun, who administered naloxone to an Ottawa resident experiencing an opioid overdose. In recognition of his life-saving actions, he was awarded the Chief of the Defence Staff Commendation.

Local initiatives are also helping build knowledge, skills, and supportive environments. At CFB Esquimalt, a recent naloxone workshop provided Defence Team members with practical knowledge and skills to respond to an overdose emergency.

Visit Stop Overdoses to learn how to recognize and respond to an overdose, reduce overdose risk, and how to have supportive conversations about substance use.

Supporting yourself and others through iCARE

Reducing stigma can help create an environment where people feel more comfortable seeking support. Recovery is possible, and with the right care, CAF members can recover from substance use disorders and continue successful careers. By staying informed, caring for one another, and being prepared to act, the Defence Team can put iCARE into action while helping protect teammates, workplaces, and communities.
