In the [[context]] of [[biology]], [[poison]]s are substances that can cause disturbances to organisms, usually by [[chemical]] reaction or other activity on the [[molecular]] scale, when a sufficient [[quantity]] is absorbed by an organism. Legally and in hazardous chemical labelling, poisons are especially toxic substances; less toxic substances are labelled "harmful", "irritant", or not labelled at all.

In [[medicine]] (particularly veterinary) and in zoology, a poison is often distinguished from a toxin and a venom. Toxins are poisons produced via some biological function in [[nature]], and venoms are usually defined as biologic toxins that are injected by a bite or sting to cause their effect, while other poisons are generally defined as substances which are absorbed through epithelial linings such as the skin or gut.
