GHB is gamma-hydroxybutyrate. Historically, GHB has been promoted for body building, although the efficacy of the drug for this use has never been documented. In 1990, the FDA issued a general warning to consumers to stop using GHB because of its numerous deleterious effects. The only current FDA-approved medical use of GHB (Xyrem) is restricted for the treatment of patients with a rare neurological disorder called Narcolepsy who experience cataplexy, a condition characterized by weak or paralyzed muscles. GHB is usually a clear liquid that is colorless and odorless. It is also produced as a white crystalline powder, and in a tablet/capsule form.
GHB is a powerful synthetic drug that has euphoric and sedative effects. It acts as depressant on the central nervous system. It is rapidly metabolized by the body. The effects of the drug can be felt within fifteen to twenty minutes after ingestion. GHB can cause dizziness, nausea, vomiting, confusion, seizures, respiratory depression, and intense drowsiness. In some cases, GHB causes unconsciousness or coma. As a result, you may not be able to recall what happened to you while you were under the influence of the drug. When GHB is ingested with alcohol or other drugs, the consequences may be life threatening. Without immediate and appropriate medical care, the results may be fatal.
Several characteristics of GHB make it especially dangerous: First, it takes a very small amount (e.g., a few drops, a capful) to have a big effect. It’s easy to overdose. Second, when GHB is used alone, or when it’s mixed with alcohol and other drugs, it may cause death. Third, most of the GHB being used today is the "homegrown" variety. It is made by non-professionals in their own "street labs," kitchens, or bathtubs by mixing various chemical ingredients. There may be significant differences in the purity, concentration, and potency of various batches. The same amount taken from two separate batches may have very different effects.
