Poisons

Introduction to poisons

A poison - also called a toxin - is a substance which, if taken into the body in sufficient quantity, may cause temporary or permanent damage.

Poisons can be swallowed, absorbed through the skin, inhaled, splashed into the eyes, or injected. Once in the body, they may enter the bloodstream and be carried swiftly to all organs and tissues. Recognition features vary with the poison - they may develop quickly or over a number of days.

See the individual tips for recognition features and treatment of specific poisions.
