Swiss researchers discover biomarker to detect date-rape drug GHB for up to 72 hrs

Swiss researchers have identified a biomarker that can detect date-rape drug GHB in urine for up to 72 hours after ingestion, extending the usual 12-hour detection window. The biomarker is a compound of GHB and a sugar thought to be ribose, known as GHB-pentos. The date rape drug is excreted rapidly from blood and urine, leaving little time to test.
