Gamma-hydroxybutyrate, or GHB, is an illegal drug that is sometimes used as a ‘party drug’ in the dance and club scene. It produces feelings of euphoria, relaxation and sociability, and an increased urge for sex. GHB acts as a nervous system depressant and poses a risk for dependence. . Even a small increase in dose can cause serious effects or death.
GHB is often known as ‘liquid ecstasy’, but it is a completely different drug to ecstasy. Other names for GHB include grievous bodily harm (GBH) or fantasy.
How GHB is used
GHB was first manufactured and studied in the 1960s and used as a general anaesthetic. It was also widely available in the 1980s as a dietary supplement and bodybuilding product. GHB has since been withdrawn from use in many countries because of unwanted side effects. It is now an illegal (illicit) drug in Australia. GHB is sometimes used to spike drinks and has been involved in cases of sexual assault. It is easy to slip it into a drink, because it has no colour or smell and it can cause drowsiness, sleep and short-term memory loss. This means that victims may not be able to resist or recall a sexual assault. For this reason, it is sometimes known as a ‘‘ drug.
How GHB works
GHB is a depressant that occurs naturally in the brain and has sedative and anaesthetic effects. Depressant substances slow down the activity of the brain and other parts of the central nervous system. Other drugs that have depressant effects include alcohol, heroin and benzodiazepines.
GHB comes in a few forms including:
- a colourless, odourless, bitter or salty-tasting liquid – sold in small bottles or vials
- a coloured liquid
- crystals or powder (this is less common).
Common effects of GHB
Generally, the effects of GHB are felt within 15 minutes and last for around three hours. GHB effects vary greatly depending on the amount used. A small increase in amount can result in a dramatic increase in its effects. This is one of the most dangerous aspects of using GHB. There is a very small difference between the amount a person may take to produce the desired effect and the amount that results in overdose.
In moderate amounts, GHB can produce feelings of:
- lack of inhibition
- an increased urge for sex
- heightened sensitivity to touch.
High dose effects of GHB
High doses of GHB can result in:
- tunnel vision
- loss of coordination (ataxia)
- confusion, irritation and agitation
- blackouts and memory lapses
- respiratory arrest (stopping breathing) and death.
GHB – dependence, tolerance and withdrawal
GHB dependence can be psychological, physical or both. People who regularly use GHB can develop a tolerance and dependence very quickly. This means they want to take larger and larger doses to try and achieve the same effect. However, this tends to increase the intensity of the unpleasant side effects instead.
If you are physically dependent on GHB and you stop taking it, you may experience withdrawal symptoms because your body has to readjust to functioning without GHB. Withdrawal symptoms can be very serious and potentially life threatening. They usually start about 12 hours after the last dose and can continue for about 15 days.
Sudden withdrawal from high doses may result in serious symptoms and may require medical assistance. If you want to stop using GHB, speak to a medical professional first.
