Appearance
GHB is a central nervous system depressant that is sold either as a powder or a clear odourless liquid. Once dissolved in a drink, it is virtually undetectable. GHB is usually taken orally.
The average dose ranges from one to five grams and the effects of the drug are felt in anything from 15 to 30 minutes. The immediate effects of the drug can last from three to six hours.
At very light dosages, these effects may include relaxation of muscle tone, sleepiness and the loss of inhibitions. At higher doses, heart rate and respiration will start to slow down and blood circulation, motor-coordination, speech control and balance will also be negatively affected.
GHB is a nervous system depressant. When combined with alcohol, its depressant effects can be dangerously intensified, leading to unconsciousness or coma.
The side effects of using GHB may include nausea, delusions, depression, amnesia, hallucinations, loss of consciousness and coma.
Regular users of the drug are at risk of becoming addicted. Quitting the drug can involve some severe withdrawal symptoms.
GHB is also used as a so-called rape drug.
During the 1980's, GHB was available over the counter for its muscle-building properties. It was particularly popular among body builders.
