poisonous substance
Harmful if ingested
A poisonous substance is any material that causes harm, illness, or death when introduced into the body through ingestion, inhalation, or absorption.
The term appears frequently in legal and regulatory contexts: The label warned that the container held a poisonous substance.
Unlike venom, which must be injected, poisons typically enter through contact or consumption.
