# Poisons

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

## What are Poisons?

Poisons are substances that can cause harm or death when introduced into the body. They can be ingested, inhaled, injected, or absorbed through the skin.

Poisons are substances that can cause harm to living organisms through chemical reactions or other molecular activity. They can enter the body through ingestion, inhalation, absorption, or injection. The severity of poisoning depends on the type of poison, the amount, and the duration of exposure.

Some poisons, like cyanide, are highly toxic and can cause immediate harm even in small amounts, while others may require prolonged exposure to become harmful. Poisons can affect various body systems, leading to symptoms such as nausea, vomiting, diarrhoea, abdominal pain, respiratory distress, seizures, and even death.

Prevention of poisoning involves safe storage and handling of hazardous substances. Medicines, chemicals, and household products should be kept out of reach of children, preferably in locked or child-resistant cabinets. Proper labelling and disposal of chemicals and medications are also crucial.

In the event of poisoning, the primary goal is to prevent further absorption of the poison and to provide supportive care. This may involve administering activated charcoal, which can absorb certain poisons in the gastrointestinal tract, or using antidotes that counteract specific poisons. Immediate consultation with the Poisons Information Centre is essential to obtain tailored advice for managing the situation and preventing complications.
