Toxicology is defined as the study of the nature, effects and treatments of poisons and toxins. While many poisonings lead to death, toxicology can also be used to establish if drugs were administered such as in the case of date rape. In his book, Invisible Evidence, Bill O’Brien explains how toxicologists look for and identify poisons and toxins.

What Kind of Poisons and Drugs can be Identified

A poison is any substance that can harm or kill a living being and includes alcohol and drugs as well as substances such as cyanide and arsenic. If a particular poison is suspected of being in a person’s body, there are often specific tests that can be carried out to identify it.
