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

Drug 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

Drug 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.

An Investigation Into the Yields of 3,4‐Methylenedioxyphenyl‐2‐propanone (MDP2P) From Glycidate Pre‐Precursors

Drug Testing and Analysis, EarlyView.
Hydrolysis of the glycidate pre‐precursors MMDMG and EMDMG was evaluated for MDP2P production. Acid hydrolysis of MMDMG (HCl, 100°C, 18 h) yielded the highest MDP2P recovery (79%), whereas base hydrolysis produced only slightly lower yields (73%), demonstrating both pathways are effective routes to this key MDMA precursor.

Population Pharmacokinetics and Detection Times of Betamethasone After Intravenous, Intramuscular, and Intranasal Jet Administration of Betamethasone Sodium Phosphate in Horses

Drug Testing and Analysis, EarlyView.
Betamethasone concentrations in 20 horses from Japan and Germany following IV, IM, and INJ administration of betamethasone phosphate were analyzed using population pharmacokinetic modeling. For IV administration of 0.04 mg/kg q24 h, IPC and IUC were 0.012 and 0.31 ng/mL, respectively; the IUC approximated the IFHA urine ISL (0.20 ng/mL).

First Occurrence of Fatal Intoxication Involving Methiodone (IC‐26) in Finland; a Medicolegal Autopsy Case Report

Drug Testing and Analysis, EarlyView.
ABSTRACT Methiodone (IC‐26) is a non‐fentanyl novel synthetic opioid which has recently been detected in drug seizures in Europe. There is still limited data about the drug in published toxicological case work, both in non‐fatal and fatal cases. We present a medicolegal autopsy case report on a fatal intoxication in an individual undergoing opioid ...

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

Drug 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.

Impact of Drone Versus Car Transport on Anti‐Doping Sample Integrity Over Short Distances: A Proof‐Of‐Concept Study

Drug Testing and Analysis, EarlyView.
This proof‐of‐concept study evaluated the impact of short‐distance drone transport on anti‐doping sample integrity compared with traditional car transport. Targeted assays and untargeted metabolomics revealed equivalent biological profiles between methods, confirming that drone delivery preserves sample integrity for the athlete biological passport ...

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

Drug 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.

Simultaneous Detection of Steroid Esters and Multi‐Class Substances in Dried Blood Spots by LC‐HRMS/MS From a Single Spot for Human Doping Control

Drug Testing and Analysis, EarlyView.
A validated LC‐HRMS/MS method enabled, for the first time, the comprehensive detection of steroid esters and multi‐class menu substances from a single dried blood spot. Following extraction, the resulting extract is split into two aliquots, reducing sample consumption and simplifying the analytical workflow.

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

Drug 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.
