Gamma hydroxybutyrate (GHB or "G") is taken by mouth, usually in liquid form. It is similar to ketamine or alcohol in its effects.

(See also Drug Use and Abuse.)

Symptoms

GHB produces feelings of relaxation and tranquility. It may also cause fatigue and feelings of being uninhibited.

At higher doses, GHB may cause

At high doses, GHB can also slow breathing and cause seizures and coma, sometimes leading to death. Combining GHB and any other sedatives, especially alcohol, is extremely dangerous. Most deaths have occurred when GHB was taken with alcohol.

Withdrawal symptoms occur if GHB is not taken for several days after previous frequent use. Withdrawal can be life threatening.

Diagnosis

Treatment

  • Treatment for symptoms

Treatment complications from GHB use is directed at symptoms. A ventilator may be needed if breathing is affected. Most people recover rapidly.
