Trends in toxicological findings and drug seizures of MDMA in New Zealand from 2010 to 2022. [PDF]

J Forensic Sci
Abstract 3,4‐Methylenedioxymethamphetamine (MDMA) or “ecstasy,” is a commonly used drug worldwide, including in New Zealand, where 4.8% of the population aged 15 years or over reported using it in a 2023/2024 survey. This study provides additional insights on MDMA prevalence data in New Zealand by reporting toxicology data from Coronial and driving ...

Recreational Drug Use at a Music Festival: A Dual Approach Using Hair Biomarkers Analysis and Participant Self-Reported Drug Use. [PDF]

Drug Test Anal
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.

Suitability of Electrochemical Sensing on Screen‐Printed Carbon Electrodes for the Identification of Eutylone (βk‐EBDB)

Electroanalysis, Volume 38, Issue 3, March 2026.
Voltammetric methods on screen‐printed carbon electrodes were employed for the rapid detection of the synthetic cathinone β‐keto‐ethylbenzodioxolylbutanamine (βk‐EBDB) in supporting electrolyte and human biological fluids. The electroanalytical method is promising as a portable drug testing device for on‐site applications—providing a repeatable linear ...

Utilizing Caenorhabditis Elegans as a Rapid and Precise Model for Assessing Amphetamine‐Type Stimulants: A Novel Approach to Evaluating New Psychoactive Substances Activity and Mechanisms

Advanced Science, Volume 12, Issue 17, May 8, 2025.
This study uses Caenorhabditis elegans to assess the activity of amphetamine‐type stimulants (ATS) and their analogs. The research highlights the roles of dopamine and serotonin pathways, distinguishes chiral forms of ATS, and identifies structure‐activity relationships. These findings provide a rapid and cost‐effective model for evaluating the effects
