International Overdose Awareness Day

International Overdose Awareness Day is a very important observance held on August 31 to raise awareness about the dangers of drug use and overdose. This day is dedicated to remembering those who have lost their lives due to overdoses and supporting their families.

History

International Overdose Awareness Day was first proposed in 2001 by Peter Strecker and Sally Jay Finn, both members of the Salvation Army in Melbourne. Since 2012, the event has been coordinated by the Penington Institute, a non-profit organization in Australia focused on drug harm prevention. Today, the awareness campaign has spread worldwide.

What is an overdose? An overdose occurs when drugs or psychoactive substances are taken in amounts that threaten health and life. It may be accidental or intentional and is often caused by using medications or substances in excess of what is prescribed or typically used. Overdoses can result in severe health consequences, including disorientation, seizures, respiratory or cardiac depression, coma, and death.

Important Information

Recognizing the signs of overdose can save lives. Watch for the following symptoms:

• Abnormally dilated or constricted pupils, or pupils that do not respond to light changes.
• Sudden agitation or, conversely, severe drowsiness and unresponsiveness.
• Unusual skin temperature—very hot and dry, or cool and clammy with cold sweat.
• Disorientation in time and space.
• Difficulty breathing, irregular heartbeat, or unstable blood pressure.
• Nausea or vomiting.

If you observe someone with these symptoms, call emergency services immediately.

How to Take Part

There are many ways to participate in International Overdose Awareness Day. Spread awareness about the dangers of drug and alcohol abuse on social media, organize or join local events, or support organizations that help those affected by overdoses.
