What class of drug is GHB or was it considered a group under

GHB (gamma-hydroxybutyrate) is classified as a central nervous system (CNS) depressant. It was originally developed as an anesthetic and later used in treatment for certain medical conditions, including narcolepsy. However, due to its potential for abuse and its association with recreational use and drug-facilitated sexual assault, GHB is regulated in many countries. In the United States, for example, it is classified as a Schedule I controlled substance under the Controlled Substances Act, meaning it is considered to have a high potential for abuse and no accepted medical use except in very specific formulations (like sodium oxybate, which is used for narcolepsy).
