Introduction: Glutathione S-transferase (GST) has the ability to detoxify the cellular environment of xenobiotic compounds and by-products of oxidative stress. The expression levels of GST genes and their polymorphisms are associated with various human diseases. Methamphetamine and opiate addiction also account for a significant proportion of SUDs in Iran.

This study presents the development and validation of a drug testing method in hair, employing a semi-automated sample preparation procedure and gas chromatography-tandem mass spectrometry (GC-MS/MS) for simultaneous multidrug analysis in hair. The method aims to detect and quantify multiple drugs in hair, including amphetamine, methamphetamine, 3,4-methylenedioxyamphetamine, 3,4-methylenedioxymethamphetamine, ketamine, norketamine, cocaine, benzoylecgonine, morphine, codeine and 6-monoacetylmorphine, using a comprehensive procedure involving decontamination, pulverization, clean-up using supported-liquid extraction (SLE) and a two-step derivatization process. The method validation included specificity, linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy, carryover, robustness and stability.

Background: Aminoglycoside antibiotics (AGs) are commonly utilized in both human and veterinary medicine to treat and manage a range of infections. These antibiotics are recognized for their narrow therapeutic window, with an overdose potentially resulting in severe side effects like kidney and ear damage. Hence, the implementation of a quick, precise, and on-the-spot testing method is crucial in clinical settings.
