Origin and Interpretation of Low Methamphetamine Levels Found in Amphetamine‐Positive Urine Samples: Support for Methylation of Amphetamine as a Minor Metabolic Pathway

Drug Testing and Analysis, EarlyView.
A low urinary concentration of methamphetamine less than 1% of the amphetamine level may not necessarily indicate polydrug use. Instead, it could result from N‐methylation of amphetamine. Chiral analysis of both amphetamines is an effective method for distinguishing between illicit use and therapeutic sources in positive drug screening results ...

Biosynthesis and Identification of Clenbuterol Metabolites in Urine and In Vitro Microsome Incubation Samples Using UHPLC‐Q‐Exactive Orbitrap Mass Spectrometry: A Comparison Between Human and Bovine Metabolism

Drug Testing and Analysis, EarlyView.
Clenbuterol metabolism was studied in bovine and human urine using LC‐Q‐Exactive‐Orbitrap MS; eight metabolites were identified in human and bovine samples as well as a novel N‐methylated form. Four urinary metabolites specific to cattle were detected and identified.

Identification of Candidate Blood Biomarkers of Recombinant Human Erythropoietin Administration Using Targeted Polar Metabolomics by HILIC‐MS/MS

Drug Testing and Analysis, EarlyView.
Using targeted HILIC‐MS/MS metabolomics, inosine and hypoxanthine were identified as potential biomarkers of EPO administration. Their consistent and sensitive plasma responses highlight their promise for inclusion in the Athlete Biological Passport (ABP), warranting further investigation to enhance anti‐doping detection strategies.

Identification of Tetrahydrocannabidiol Metabolites in Human Urine

Drug Testing and Analysis, EarlyView.
The detection of Phase I and II metabolites of tetrahydrocannabidiol (H4CBD) in urine after oral ingestion of 25‐mg H4CBD by a volunteer is described. The proposed metabolite structures are based on ESI+ spectra recorded by HPLC‐HRMS and EI spectra after trimethylsilylation recorded by GC–MS.
