Gamma-hydroxybutyric acid, or GHB, is a psychoactive drug that naturally occurs in the brain as a neurotransmitter. It has been used medically as an anesthetic and for treatment of narcolepsy.
Be careful not to confuse gamma butyrolactone (GBL) with gamma hydroxybutyrate (GHB).
Despite serious safety concerns and illegality, people take GBH gamma butyrolactone for improving athletic performance, sleep, and sexual performance and pleasure. They also take it for relieving depression and stress, prolonging life, promoting clear thinking, causing relaxation, and releasing growth hormone.
GBL is also used to trim fat and as a body- or muscle-builder.
Others take it as a recreational drug.
When used recreationally, users report effects similar to alcohol and, like MDMA, it is often used in clubs and at raves.
In rat studies, GHB has shown to be habit forming, and some users report feeling withdrawal symptoms after stopping use.
