Among drivers stopped in Belgium in 2015, 7% of blood samples and 11% of oral fluid samples contained new psychoactive substances (NPS), including diphenidine, ketamine, mephedrone, and synthetic cannabinoids. Additionally, 17% of blood samples contained an analgesic drug, 10% a benzodiazepine or hypnotic, and smaller proportions antidepressants, antipsychotics, antiepileptics, or methylphenidate. Poly-drug use combining NPS with licit drugs and drugs of abuse was common. The findings demonstrate that NPS are present in the predominantly young male driving-under-the-influence population and highlight the need for on-site detection methods and further research on combined drug effects on driving ability.

Lysergic acid diethylamide (LSD) is a potent hallucinogen active at very low doses, making its detection and quantification difficult in body fluids and especially in hair. This review examines the challenges of LSD hair analysis, noting that only ten published cases provide data on LSD concentrations in hair. Interpretation of results is complicated by possible pubic hair contamination from urine and limited understanding of how LSD incorporates into and remains stable in head and pubic hair. The absence of LSD in head hair does not rule out consumption, and positive results cannot reliably distinguish single from repeated use. Even a positive pubic hair result does not formally prove repeated LSD use.

Ayahuasca, a traditional Amazonian psychoactive brew, is the subject of a letter to the editor. The letter likely discusses aspects of ayahuasca's composition, effects, or research context, though the abstract is truncated and does not provide a complete finding or argument. The available text only identifies the substance and its traditional use, without presenting a specific result, claim, or analysis.
