Detection of Nitazenes in the Illicit Drug Supply Utilizing Precursor Ion Scan Methods With Paper Spray Mass Spectrometry

open access: yesDrug Testing and Analysis, EarlyView.
Nitazenes are increasingly present in the illicit drug supply, complicating harm reduction efforts. We have developed a rapid, nontargeted precursor ion scan method to detect emerging nitazenes in real‐world opioid samples. The method identified multiple nitazenes, often replacing pharmaceutical opioids or mixed with fentanyl and benzodiazepines ...

Monitoring Injected Drug Use in Greece Through Syringe Residue Analysis: A Multicity Study Within the ESCAPE Network

open access: yesDrug Testing and Analysis, EarlyView.
A total of 2121 used syringes were analyzed in Athens, Thessaloniki, and Patras between 2022 and 2024. Distinct drug‐use patterns were observed across the three cities. Benzodiazepines, pregabalin, methadone, and fentanyl were increasingly detected in 2024.

Supercritical Fluid Chromatography for Expedited Sample Clean‐Up in Isotope Ratio Mass Spectrometry Including Cholesterol as New Endogenous Reference Compound

open access: yesDrug Testing and Analysis, EarlyView.
Supercritical fluid chromatography was employed in the sample preparation for IRMS determinations in sports drug testing for the first time and the developed method was successfully validated. Cholesterol (CHOL) was introduced as a novel endogenous reference compound and population‐based Δ‐values were established as shown here.

Comprehensive Evaluation of Commercial Antibodies for High Sensitivity Detection of EPO‐Doping on Western Blots

open access: yesDrug Testing and Analysis, EarlyView.
A large‐scale evaluation of 164 commercially available anti‐human EPO antibodies was conducted to identify an alternative to clone AE7A5 anti‐EPO antibody used in doping control for the detection of erythropoiesis‐stimulating agents (ERAs) on Western blots.

Estimating Illicit Stimulant Drug Consumption in Luxembourg Using Wastewater‐Based Epidemiology

open access: yesDrug Testing and Analysis, EarlyView.
Wastewater‐based epidemiology provided nationwide estimates of illicit stimulant consumption in Luxembourg, revealing higher urban use, weekend increases in cocaine and MDMA, and cocaine as the dominant stimulant. The approach offers an objective complement to conventional drug surveillance for informing public health and policy.

A Single‐Aliquot Strategy for Simultaneous Carbon Isotope Confirmation of 6‐Oxo‐Androstenedione and Testosterone Misuse in Doping Control

open access: yesDrug Testing and Analysis, EarlyView.
This method enables simultaneous carbon isotope confirmation of 6‐oxo‐androstenedione and testosterone markers from a single urine aliquot, using bench‐top extraction, two preparative HPLC steps with intermediate acetylation, and GC/C/IRMS analysis. It was fully validated according to WADA requirements, and real samples demonstrated its fitness for ...
