• Swiss researchers from the University of Zurich have discovered a new method to detect Gamma-Hydroxybutyrate (GHB), commonly known as a date-rape drug, in urine.

• The new method can detect evidence of GHB consumption for up to 72 hours (3 days) after ingestion.

• This may help improve investigations into sexual assault cases.

Key Highlights

1. What is GHB?

• GHB stands for Gamma-Hydroxybutyrate.

• It is a substance that affects the central nervous system.

• It can cause unconsciousness, drowsiness and memory loss.

• It is sometimes secretly mixed into drinks to facilitate sexual assault.

2. Problem with Traditional Detection:

• GHB disappears quickly from the body.

• It is generally detectable for around 6 hours in blood and 12 hours in urine.

• This makes timely testing difficult.

3. New Discovery:

• Researchers identified a biomarker called GHB-pentose.

• It is formed when GHB interacts with a sugar-like compound in the body.

• Unlike GHB itself, this biomarker remains detectable in urine for a longer period.

1. Detection Window:

• The new biomarker may remain detectable for up to 3 days after GHB intake.

• It provides a longer period for collecting forensic evidence.

5. Significance:

• Helps improve forensic investigations.

• May support evidence collection in sexual assault cases.

• Can help investigators identify suspected drug exposure even after GHB itself disappears.
