Chemical Straightening as a Source of Analytical Variability in Hair Testing: A Dual‐Analyte Case Report

open access: yesDrug Testing and Analysis, EarlyView.
ABSTRACT Hair analysis is increasingly used in forensic toxicology; however, result interpretation may be influenced by cosmetic hair treatments. Although the effects of bleaching, dyeing, and thermal straightening have already been evaluated, data on permanent chemical hair straightening are scarce, particularly under in vivo conditions.

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

open access: yesDrug 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.

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

open access: yesDrug 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.

Determination of THC and THC‐COOH in Dried Capillary Blood Spots and Comparison to Venous Blood of Recreational Cannabis Consumers in a Pilot Study

open access: yesDrug Testing and Analysis, EarlyView.
A new extraction method was developed and validated for the extraction of THC and THC‐COOH from capillary blood samples collected as dried blood spots. The extracts were analysed using HPLC–MS/MS resulting in high extraction efficiencies for both THC and THC‐COOH.

Green degumming of industrial hemp fibers: Property enhancement and application in hemp/cotton blended yarns

open access: yesIndustrial Crops and Products
Waste fibers generated during hemp fiber processing (hemp noil) are often disposed of as solid waste due to inadequate treatment technologies, causing resource waste and failing to meet the demand for high-quality fibers in yarn production.
