Influence of Different Washing Hair Procedures in the Quantitative Determination of THC and THCCOOH

Drug Testing and Analysis, EarlyView.
Different hair decontamination protocols significantly affect THC quantification, with marked analyte loss—particularly after aqueous‐organic washing—whereas THCCOOH remains stable. These findings highlight the risk of misinterpretation and the need for standardized washing procedures in hair analysis.

Detection of the GH Analogue Redalsomatropin Alfa in Sports Drug Testing: Immunological Approaches and LC‐HRMS/MS

Drug Testing and Analysis, EarlyView.
After evaluating the compatibility of the GH analogue redalsomatropin alfa with approved doping control immunoassays for rhGH, it was implemented into the existing detection method for somatrogon employing affinity purification with GHR‐Fc‐conjugated magnetic beads, tryptic digestion, and LC‐HRMS/MS to allow for a specific and sensitive detection ...

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.

Examining Phosphatidylethanol (PEth) Formation Rates Within and Between Subjects in Ex Vivo Whole Blood

Drug Testing and Analysis, EarlyView.
PEth formation rate increased with increasing ethanol concentration with variability between participants but was mostly consistent within‐subject. No relationship was observed between phosphatidylcholine concentrations and PEth formation rates. PEth concentrations should be used to monitor an individual's ethanol use over time, rather than compared ...

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.

Filtering Trust: Disclosing the Role of Artificial Intelligence Decreases Trust in Technology, but Does Not Prevent Harm to Body Image After Viewing AI‐Generated Content

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objectives Despite the rapid growth of generative artificial intelligence (AI), virtually no research exists examining the psychological impacts of viewing or interacting with AI‐generated images of people. Additionally, it remains relatively unknown whether informing viewers when images are AI‐generated is an effective way to lessen harm or ...
