What is GHB?
GHB is also known as fantasy, grievous bodily harm, GBH, liquid ecstasy, liquid E, G, or Gina.
GHB is short forgamma-hydroxybutyrate and it is naturally produced in small amounts by the body. It is almost always sold as a clear or blue liquid that doesn't have a smell. It comes in a little vial such as fish-shaped sushi soy sauce container and it is normally swallowed. Problems with safety, including concerns about its use as a date rape drug, have led to it being classified as an illegal drug.
Sometimes other substances called GBL and 1,4B are sold as GHB because they have similar effects but may be stronger or more toxic. This increases the change of an overdose.
Although it is sometimes referred to as liquid ecstasy or liquid E, it is not related to ecstasy at all.
There’s a very high risk of overdosing with GHB. There’s very little difference between the amount that causes the ‘high’ and the amount that causes an overdose.
What are the effects?
Once swallowed, GHB takes around 15–30 minutes to take effect and the effects last for about half an hour.
Effects of GHB vary but may include:
- Increased heart rate and chest pains
- Drowsiness, passing out, blackouts or memory loss
- Blurred vision
- Feeling relaxed
- Feeling of euphoria (a ‘high’)
- Hot/cold flushes
- Heavy sweating
- Confusion and agitation
- Nausea and vomiting
- Headaches and dizziness
- Tremors or shaking
- Difficulty breathing
