GHB (date rape) Test

GHB Drug Testing

There are increasing reports of abusing Gamma-Hydroxybutyric acid (GHB). GHB is also typically associated with sexual assault or as a "date rape" drug due to its severe hypnotic and sedative effects at higher dosages. Typical illicit use of GHB involves dissolving 2-3 grams of powder in beverages.
