Gamma-Butyrolactone, Also Known As Gamma-butyrolactone, GBL, GHB, GBH, Gabba, G, Liquid Ecstasy
GBL (gamma-butyrolactone) is closely related to gamma-hydroxybutyrate (GHB); both are dangerous drugs with sedative and anaesthetic effects. GBL converts to GHB shortly after entering the body. It is a common solvent used in products like paint strippers and stain removers.
Colourless, odourless liquid. Sometimes it also comes in capsule form.
GHB and GBL produce essentially the same effects and vary greatly in strength. They both produce a feeling of euphoria and can reduce your inhibitions and make you feel sleepy.
GHB Short term: Larger doses can cause drowsiness, sickness, disorientation, convulsions, coma and breathing difficulties. Can cause nausea, reduced heart rate, drowsiness, coma, hypothermia, seizures, unconsciousness, coma and death. Due to their effect GHB and GBL have been linked to drug-assisted sexual assault.
GHB Long term: Long term effects are not well understood. Using both GHB and GBL can cause unconsciousness, coma and death. Even experienced users are at risk from death by intoxication. Taking these drugs with alcohol or other sedative drugs adds to the risk of harm. But it is also clear that they can cause death when taken on their own.
