Recreational Drug Use at a Music Festival: A Dual Approach Using Hair Biomarkers Analysis and Participant Self‐Reported Drug Use

Drug Testing and Analysis, EarlyView.
Combined self‐report and hair analysis in festival attendees (n = 249) revealed substantial discrepancies in drug use reporting, particularly for stimulants and dissociatives. This integrated approach enhances detection of poly‐drug use and provides a more reliable basis for monitoring and harm‐reduction strategies.
