Gamma hydroxybutyrate (GHB, G, fantasy, liquid ecstasy, Gina) and Gamma-Butyrolactone (GBL) are depressants with strong sedative effects. They look very similar and are hard to tell apart. However, GBL is stronger and easier to overdose, because it is converted to GHB in your body after you take it.

Both usually come as a clear liquid with a bitter aftertaste, but they can also be a white powder or a bright blue liquid called ‘blue nitro’, which can be swallowed as a liquid or mixed in a drink.

GHB slows down the body and can make you feel euphoric, sexually aroused, groggy and nauseous. It can also cause memory lapses, loss of motor control, dizziness, headaches, lowered body temperature and heart rate, diarrhoea and difficulties urinating.
