Insights from a six‐year hair drug analysis compendium in drug‐facilitated crimes involving vulnerable population cases

Journal of Forensic Sciences, EarlyView.
Abstract Hair analysis is a well‐established matrix in forensic toxicology, offering a valuable alternative or complement to traditional matrices in diverse contexts, including drug‐facilitated crimes (DFC), elder abuse, and accidental exposure in children.

Urinary concentrations of codeine and morphine after the administration of different codeine preparations in relation to doping analysis

, 1991
A capillary GC method with nitrogen-specific detection is described for the analysis of codeine and morphine in urine. Both drugs were determined after enzymatic hydrolysis of the urine. Morphine was derivatized with trifluoroacetic anhydride.

Insights from a 6‐year hair drug analysis compendium in drug‐facilitated sexual assault cases

Journal of Forensic Sciences, EarlyView.
Abstract Drug‐facilitated sexual assault (DFSA) may involve a diverse array of substances, including illicit drugs, prescription medications, and over‐the‐counter pharmaceuticals. Hair analysis has emerged as a valuable forensic tool, offering an extended window of detection spanning several months. However, interpreting drug concentrations in hair can

Physiologically based pharmacokinetic modeling to predict the pharmacokinetics of codeine in different CYP2D6 phenotypes

Frontiers in Pharmacology
ObjectivesCodeine, a prodrug used as an opioid agonist, is metabolized to the active product morphine by CYP2D6. This study aimed to establish physiologically based pharmacokinetic (PBPK) models of codeine and morphine and explore the influence of CYP2D6

Evaluation of illicit drug contaminants in seized cannabis in Arizona and California, 2023–2024

Journal of Forensic Sciences, EarlyView.
Abstract Despite public health concerns, fentanyl, cocaine, and other illicit drug contaminants remain largely understudied in unregulated cannabis. Here, we developed an analytical method to quantify a panel of common illicit drugs in cannabis and tested the law enforcement seizures in Arizona and California in evaluation of the illicit drug ...
