    Area of Science:

    • Forensic toxicology
    • Pharmacology
    • Traffic safety

    Background:

    • Diazepam (Valium) is a commonly prescribed sedative.
    • Drug and alcohol use among drivers is a significant public health concern.
    • Assessing the prevalence and impact of diazepam in impaired driving cases is crucial.

    Purpose of the Study:

    • To determine the prevalence of diazepam in drivers' blood samples.
    • To investigate the co-occurrence of diazepam and alcohol in drivers.
    • To evaluate the potential driving impairment associated with diazepam levels.

    Main Methods:

    • Analysis of 1500 drivers' blood samples over three years.
    • Gas chromatography or mass spectrometry for drug detection.
    • Blood alcohol concentration (BAC) testing.

    Main Results:

    • Diazepam detected in 2.0% of 1000 hospitalized drivers.
    • Alcohol detected in over 90% of hospitalized drivers.
    • Lower prevalence of diazepam in fatally injured and low BAC apprehended drivers.

    Conclusions:

    • Diazepam is present in a small percentage of drivers.
    • Co-ingestion of alcohol and diazepam may increase driving impairment.
    • Further research is needed to establish definitive impairment thresholds for diazepam.
