GHB (gamma hydroxybutyrate) is a depressant drug that slows down the messages travelling between the brain and body.1
GBL (gamma butyrolactone) and 1,4-BD (1,4-butanediol) are chemicals that are closely related to GHB. Once GBL or 1,4-BD enter the body, they convert to GHB almost immediately.2
GHB usually comes as a colourless, odourless, bitter or salty liquid, which is usually sold in small bottles or vials. It can also come as a bright blue liquid known as ‘blue nitro’, and less commonly as a crystal powder.2

If the dose is too high, you might overdose. If you have any of these symptoms, call an ambulance straight away by dialling triple zero (000). Ambulance officers do not have to involve the police.
Little is known about the long-term effects of GHB use. However, it is known that regular use can lead to tolerance and dependence, which means larger amounts of GHB are needed to get the same effect.
Using GHB to help with the symptoms of the come down after using stimulants can lead to an addiction to both drugs.
Giving up GHB after using it for a long time is challenging because the body has to get used to functioning without it. This is why it’s important to speak to a health professional when planning to stop using GHB.
Withdrawal symptoms usually start about 12 hours after the last dose and can continue for about 15 days.
These symptoms can include:
Sudden withdrawal from high doses can result in bowel and bladder incontinence and blackouts7.
