GHB (gamma-hydroxybutyrate), often called "G" or "Liquid Ecstasy," is a synthetic central nervous system depressant. It is frequently misused recreationally for its relaxing effects, enhanced social interactions, and heightened sexual experiences. Its addictive potential comes from the intense pleasure and euphoria it produces.
Individuals commonly combine GHB with substances like crystal meth, methamphetamine, mephedrone, cocaine, and ketamine, significantly increasing the risk of polysubstance addiction. Due to its reputed enhancement of sexual experiences, GHB is strongly linked to the Chemsex scene.
