The difference between poisons and toxins

I just learned the technical difference between things that are poisonous and things that are toxic.

Toxins are produced biologically, where as poisons are anything that kills you. (Venom being a toxin injected through a bite or sting.) Behold my glorious Venn diagram.

So snake venom is a poisonous toxin, ricin is a toxin and a poison but not a venom, and arsenic is just poisonous.

Since latex is produced biologically, it’s both a toxin and a poison.

Learning!
