Gamma-Hydroxybutyrate (GHB) is a naturally occurring substance in the central nervous system. It is often used as a recreational drug due to its sedative and euphoric effects. GHB can also be synthesized in a laboratory and is sometimes used in medical settings to treat conditions like narcolepsy. In addition to its medical uses, GHB has gained notoriety for its association with drug-facilitated crimes. It is classified as a controlled substance in many countries, making its non-medical use illegal. Users should be aware of the potential for addiction and serious side effects.
