Our vision is a world without overdose
Every August 31, International Overdose Awareness Day (IOAD) brings a global community together to take action on overdose.
It is a global platform that provides tools, resources and a space for communities to connect and drive change.
Through events – both in person and online – communities honour lives lost, educate their families, friends and peers and explore evidence-based overdose prevention solutions.

What drives us
The International Overdose Awareness Day campaign is guided by 6 principles.
Overdose can and must be prevented
Overdose prevention solutions exist – let’s use them.
Criminalizing drug use hasn’t worked. Compassionate alternatives must be pursued.
Policy and legislation must exist to protect individuals and communities, and ensure basic human rights and needs are met.
Everyone has a right to respectful and comprehensive health care.
Only a community-wide effort can end overdose.

How it began
International Overdose Awareness Day begins as a BBQ remembrance event at The Salvation Army needle exchange in Melbourne, Australia.
Penington Institute takes the lead, transforming a local event into a global day of action.
IOAD adopts overdose prevention as a core campaign ambition, alongside remembrance.
Communities around the globe embrace the day, holding events, sharing stories, and building momentum for change.
Thousands of voices, 1,000+ events, 40+ countries. IOAD sparks open conversations about overdose driving life-saving action.
Who is behind IOAD

Penington Institute
Penington Institute, a drug policy research non-profit, has been quietly leading International Overdose Awareness Day since 2012, transforming a single event into a global day of action.
From the start, Penington Institute championed local ownership, believing that lasting change happens when communities are empowered to find their own solutions.
This approach has allowed IOAD to grow and be focused on local priorities, driven by the voices of those most impacted.
