Liquid G is a street name for GHB (gamma-hydroxybutyrate), which is an illegal drug that acts as a nervous system depressant. It is usually available as a clear, colorless, odorless, and bitter or salty-tasting liquid, sold in small bottles or vials. GHB is also known as "liquid ecstasy," but it is a completely different drug from ecstasy. It is a designer drug that is made for the purpose of getting high, and it is popular with club-goers and at "rave" parties. GHB causes both a euphoric high and hallucinations, and it can be slipped unknowingly into a persons drink because of its odorless and colorless nature. Side effects of GHB use include drowsiness, dizziness, nausea, vomiting, and vision changes. People who take GHB may become unconscious, stop breathing, and go into a coma, and GHB use can be fatal. Mixing GHB with alcohol is very dangerous and can be deadly, even if someone has only taken low doses of the drug.
