**GHB (Gamma-Hydroxybutyric acid)** is a central nervous system depressant that occurs naturally in small amounts in the human body. It is most commonly known for its use as an illicit substance due to its sedative and euphoric effects. GHB can cause drowsiness, dizziness, nausea, unconsciousness, and memory loss, especially when consumed in higher doses. It has a narrow safety margin, meaning the difference between a recreational dose and a dangerous one is very small. GHB is often referred to as a “date rape drug” because it can be added to drinks without noticeable taste, smell, or color, making it difficult to detect.
