    Summary
    This summary is machine-generated.

    Passive inhalation of cannabis smoke can lead to detectable cannabinoids in urine. A threshold of 65 ng/ml helps differentiate passive exposure from active use.

    Area of Science:

    • Forensic Toxicology
    • Pharmacology

    Context:

    • Cannabinoid detection in urine is crucial for drug testing.
    • Distinguishing between active and passive exposure to cannabis smoke is a challenge.

    Purpose:

    • To establish a reliable urinary cannabinoid threshold for differentiating passive inhalation from active use.
    • To account for the variability in immunoassay methods for cannabinoid detection.

    Summary:

    • Cannabinoids can be present in urine due to passive inhalation of cannabis smoke.
    • Urine cannabinoid concentrations can reach 40-50 ng/ml under intense passive exposure.
    • A threshold of 65 ng/ml is proposed to distinguish passive from active cannabis inhalation, considering assay variability.

    Impact:
