# Substance Misuse

[Resources](https://www.australiawidefirstaid.com/resources) › [Glossary](https://www.australiawidefirstaid.com/resources/glossary)

## What is Substance Misuse?

Substance misuse refers to the harmful or hazardous use of substances such as drugs or alcohol, leading to addiction or overdose.

Substance misuse refers to the harmful or hazardous use of psychoactive substances, including alcohol and illicit drugs, leading to dependence, addiction, or negative health consequences.

In first aid contexts, responders may encounter individuals experiencing acute intoxication, overdose, or withdrawal symptoms related to substance misuse. Understanding the signs and symptoms of substance misuse is essential for providing appropriate care and support.

First aid response to substance misuse focuses on ensuring the safety of the casualty and those nearby, assessing the casualty's level of consciousness and vital signs, and contacting emergency medical services as needed.

Providing reassurance, maintaining a calm environment, and monitoring the casualty's condition are key priorities. Collaborating with healthcare professionals and community resources supports ongoing management and referral for substance use disorder treatment.
