Poisoning may be accidental or deliberate. Most pharmaceuticals are poisonous, even lethal in overdose. If poisoning occurs in an industrial area, farm or laboratory setting, suspect particularly dangerous agents and take safety precautions. If more than one person simultaneously appears affected by a poison, there is a high possibility of dangerous environmental contamination.

A poison can enter the body by ingestion, injection, absorption, or inhalation.
