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 ...

Toward a Cannabis Terroir: Untargeted Metabolomic Profiling of Authentic Samples Using Gas Chromatography–High‐Resolution Mass Spectrometry (GC‐HRMS) and Liquid Chromatography–High‐Resolution Tandem Mass Spectrometry (LC‐HRMS/MS)

Drug Testing and Analysis, EarlyView.
This study developed a comprehensive metabolomics workflow using GC‐HRMS and LC‐HRMS/MS and analyzed 35 CBD‐type cannabis flowers grown under varying conditions. Key discriminative compounds enabled classification by chemical phenotype and cultivation environment. The results showed that environmental factors influence chemical profiles, supporting the
