Symptoms of GHB Use
GHB produces feelings of relaxation and tranquility. It may also cause fatigue and disinhibition.
At higher doses, GHB may cause dizziness, loss of coordination, nausea, and vomiting. Coma and respiratory depression may also occur. Combining GHB and any other sedative, especially alcohol, is extremely dangerous, causing decreased mental status and episodes of apnea. Most deaths have occurred when GHB was taken with alcohol.
Tolerance and dependence can develop in frequent users.

Diagnosis of GHB Use
Usually a clinical diagnosis
Sometimes urine testing
Diagnosis of GHB intoxication is made from clinical signs and symptoms. GHB is not detected on routine urine drug screens. After its use, GHB can be detected in urine for up to 12 hours by gas chromatography/mass spectrometry.
Treatment of GHB Use
Management of symptoms
Sometimes mechanical ventilation
Treatment of GHB intoxication is directed at symptoms. Mechanical ventilation may be needed if breathing is affected or to protect the airway. Most people recover rapidly, although effects may not fade for 6 to 8 hours.
Treatment of GHB withdrawal is also similar to that for alcohol or sedative withdrawal. Administration of benzodiazepines and supportive care are the core elements of treatment.
