Identification of Tetrahydrocannabidiol Metabolites in Human Urine

open access: yesDrug Testing and Analysis, Volume 17, Issue 12, Page 2333-2346, December 2025.
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.

Detection of Anabolic Androgenic Steroids and Steroid Esters—Comparing Dried Blood Spots Collection Devices and Urine Samples

open access: yesDrug Testing and Analysis, Volume 17, Issue 12, Page 2374-2383, December 2025.
DBS (Capitainer‐B50 and Tasso‐M20) enabled detection of testosterone esters in all participants, whereas urine testing (T/E) missed cases including potential UGT2B17 del/del carriers and individuals with testosterone prescription. More AAS and steroid‐esters could be detected in Capitainer‐B50 versus Tasso‐M20.

Prevalence of AAS‐Positive Samples at Drug Abuse Laboratory Sweden Between 2014 and 2023 and Sub‐Study of Dual Use of AAS and Narcotics

open access: yesDrug Testing and Analysis, Volume 17, Issue 12, Page 2421-2428, December 2025.
Throughout 2014–2023, over 20,000 AAS analyses have been conducted at the drug of abuse laboratory, Karolinska University Hospital. Approximately 20% and 2% of the samples have been positive for AAS, with no trends of increase or decrease. Around 50% of the AAS‐positive samples were also positive for narcotics (year 2022–2023), with gender differences;

Prolonged Detection of GHB Intake in Urine: Are We Finally There?

open access: yesDrug Testing and Analysis, Volume 17, Issue 12, Page 2429-2446, December 2025.
In a randomised placebo‐controlled trial with 30 volunteers, urinary LC‐MS/MS analysis demonstrated that a tentative GHB‐pentose conjugate remained elevated in urine up to 72 h post‐administration. This biomarker showed clear distinction from placebo and may offer extended detection compared to GHB itself, representing a significant step forward in ...
