Identification and Characterization of the Designer Opioid N‐Pyrrolidino Fluetonitazene in Nasal Spray

Drug Testing and Analysis, EarlyView.
N‐Pyrrolidino fluetonitazene, a synthetic opioid, was identified and characterized in a nasal spray using GC‐MS, LC‐QTOF‐MS, NMR and FT‐IR. ABSTRACT Detection of drugs in non‐biological samples serves as a fundamental basis for identifying emerging trends in the field of new psychoactive substances and provides valuable information for optimizing ...

Recreational Drug Use at a Music Festival: A Dual Approach Using Hair Biomarkers Analysis and Participant Self‐Reported Drug Use

Drug Testing and Analysis, EarlyView.
Combined self‐report and hair analysis in festival attendees (n = 249) revealed substantial discrepancies in drug use reporting, particularly for stimulants and dissociatives. This integrated approach enhances detection of poly‐drug use and provides a more reliable basis for monitoring and harm‐reduction strategies.

Determination of THC and THC‐COOH in Dried Capillary Blood Spots and Comparison to Venous Blood of Recreational Cannabis Consumers in a Pilot Study

Drug Testing and Analysis, EarlyView.
A new extraction method was developed and validated for the extraction of THC and THC‐COOH from capillary blood samples collected as dried blood spots. The extracts were analysed using HPLC–MS/MS resulting in high extraction efficiencies for both THC and THC‐COOH.

Investigation of the In Vitro and In Vivo Metabolism and μ‐Opioid Receptor Affinity of the Nitazene N‐Pyrrolidino Fluetonitazene

Drug Testing and Analysis, EarlyView.
Eight metabolites for N‐pyrrolidino fluetonitazene were identified in vitro, three of which (M2, M6 and M8) were present in an authentic urine sample. M2 was the most abundant in vivo metabolite and is a common marker metabolite of nitazepyne‐type substances.

In Vitro Metabolism of Δ8‐, Δ9‐, and Δ10‐THC in Human Hepatocytes: Distinct Δ10‐THC Biotransformation and Implications for Drug Testing

Drug Testing and Analysis, EarlyView.
Δ8‐THC and Δ9‐THC showed comparable metabolic profiles. In contrast, Δ10‐THC underwent extensive glucuronidation and hydroxylation, with only minor formation of a carboxy metabolite, indicating a markedly different metabolic pathway. These differences may increase the risk of misidentification and misinterpretation in cannabis drug testing.
