Gamma-Hydroxybutyric acid (GHB) is a naturally occurring compound and central nervous system depressant. Although it is found in small amounts within the human body, it is better known for its illicit use due to its sedative and euphoric effects. At higher doses, GHB can cause drowsiness, dizziness, nausea, unconsciousness, memory loss, and potentially life-threatening effects. Its narrow safety margin makes the risk of overdose high. GHB is sometimes used as a “date rape drug” because it can be mixed into drinks without any noticeable taste, smell, or colour.
