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.

Segmental Hair Analysis of Diphenhydramine and Cyclizine Following a Single Dose

Drug Testing and Analysis, EarlyView.
A single oral dose of diphenhydramine and cyclizine can be quantified in human head hair for a minimum of 5 months and, in certain cases, for up to 1 year following intake. Among 12 study participants, the measured concentrations ranged from 0 to 610 pg/mg within 1 year post‐intake.
