What it is

Gamma-hydroxybutyrate (GHB) is a depressant drug that slows down messages between the brain and the central nervous system. At low doses it acts as a sedative, and at higher doses it acts likes an anaesthetic. 

GHB is usually a clear odourless liquid, though dealers and manufacturers often add coloured food dye to differentiate the drug from other liquids. It is often sold in small bottles or vials, and tastes salty or bitter. The liquid is usually mixed into a drink and taken orally.

GHB was first used in 1960 as an anaesthetic before surgery, and as a treatment for narcolepsy (uncontrolled periods of deep sleep). It was also trialled as an aid to relieve alcohol and opiate withdrawal.

GHB is now more commonly used recreationally, with some people using it instead of alcohol. It is well known as a date rape drug because large doses can be easily mixed with drinks, and its anaesthetic properties impair the memory of the victim.
