Rapid and Effective Determination of Ethyl Glucuronide in Hair by Micro Extraction by Packed Sorbent (MEPS) and LC‐MS/MS

Drug Testing and Analysis, EarlyView.
The development and validation of a MEPS method for the purification of hair extract for the EtG determination and quantification in the keratin matrix is the main focus of this study. The method is fast and effective and, as a miniaturised technique, requires only small amounts of solvent.

Associations Between Self‐Reported Cocaine Use Patterns and Cocaine and Its Metabolites in Hair: Implications for Clinical and Forensic Practices

Drug Testing and Analysis, EarlyView.
This study demonstrates that concentrations of cocaine and its main metabolites in hair reliably predict an individual's actual intensity of cocaine use and effectively differentiate between dependent and non‐dependent users. ABSTRACT In forensic toxicology, it has been debated if hair testing allows an estimation of the intensity of cocaine use—an ...

Analytical and Pharmacological Characterization of 1‐(Furan‐2‐Carbonyl)‐LSD (1F‐LSD) and Comparison With 1‐(Thiophene‐2‐Carbonyl)‐LSD (1T‐LSD)

Drug Testing and Analysis, EarlyView.
The novel lysergamide 1‐(furan‐2‐carbonyl)‐LSD (1F‐LSD) was analytically characterized. 1F‐LSD showed LSD‐like activity in vivo similar to 1‐(thiophene‐2‐carbonyl)‐LSD (1T‐LSD) used for comparison. Administration studies in mice and LC–MS analysis revealed that 1F‐LSD served as a prodrug.

Rapid and Simple Dispersive Liquid–Liquid Microextraction (DLLME) Sample Preparation for Propofol Analysis in Hair, Blood, and Urine by Gas Chromatography–Mass Spectrometry

Drug Testing and Analysis, EarlyView.
Development and validation of an extraction method based on dispersive liquid–liquid microextraction for the analysis by GC–MS of propofol in three different biological samples (blood, urine, and hair). The proposed method is very simple and rapid.

Long‐Term Stability of Ethyl Glucuronide in Hair: A 10‐Year Retrospective Analysis of 909 Samples by LC–MS/MS

Drug Testing and Analysis, EarlyView.
EtG hair analysis has a standard method for detecting alcohol abuse. In this study, we assessed the long‐term stability of EtG in hair stored up to 10 years. A total of 909 samples originally analyzed between 2013 and 2022 were re‐tested in 2023 by LC‐MS/MS.
