Introduction

Gamma-hydroxybutyric acid (GHB) is a central nervous system (CNS) depressant.

GHB can also be ingested orally and in this form it can be purchased commercially and on the illicit market. As a recreational drug, it is used by many young people for its intoxicating effects. For these purposes it has the important characteristic of passing the blood–brain barrier, unlike GABA.
