GHB (gamma hydroxylbutyrate) is a drug commonly found around the dance and party scene. It’s known as a ‘date rape’ drug, and you might not notice if GHB is slipped into your drink at a party. The main risk with GHB is from an overdose, which could kill you.
GHB is a bitter or salty tasting liquid that is odourless or has a slight odour. It can also be found in powder or pill form. GHB typically doesn’t have any colour, but can make a transparent drink cloudy or can be coloured bright blue. It is usually swallowed but sometimes it is injected or inserted anally.
GHB is also known as fantasy, GBH (grievous bodily harm), G, blue nitro and liquid ecstasy. GHB is an abbreviation of the chemical name gamma-hydroxybutyric acid.
GHB is a depressant drug, which means it slows down the messages to and from the brain. It was originally developed as a general anaesthetic, and makes people who use it drowsy.
GHB is known as a date rape drug because it can be camouflaged in opaque strongly flavoured drinks (drink spiking) such as cocktails.

The risk of overdosing on GHB is very high, especially if it’s combined with other depressant drugs such as alcohol. Find out about the physical effects of GHB.
Mental health issues
GHB overdoses can cause hallucinations, memory loss and blackouts.
Not much is known about its long-term effects, but regular use can lead to tolerance and dependence.
