Synthetic Cannabinoids and the Purinergic–Dopaminergic Axis: P2x7 as a Candidate Primary Sensor of Neuroinflammatory Injury and the Role of Adenosine Receptor Heteromers in Emerging Nps Toxicity—A Hypothesis-Driven Integrative Review

Psychoactives October 15, 2026 Felipe Heemann

Synthetic cannabinoids (SCs), marketed as Spice, K2, and dozens of successor compounds, constitute one of the most pharmacologically dangerous categories of new psychoactive substances (NPS) currently in circulation. Their extreme toxicity relative to Δ9-tetrahydrocannabinol (THC) is not fully accounted for by CB1 receptor pharmacokinetics alone. This review proposes an integrative mechanistic...

This study aimed to investigate the function of a wooden brazier excavated from the Hongshan Cemetery (5th to 3rd century BC) in Xinjiang, northwestern China. Organic residues and material composition were analysed using gas chromatography-mass spectrometry (GC-MS) and wood anatomical analysis to identify burned plant resources and explore their cultural significance. GC-MS results confirmed...

Adverse reactions to psychedelics in naturalistic settings are associated with current psychopathology and well-being: A correlational study

Psychiatry Research October 1, 2026 Jaime Rojas-Hernández, Lucas F Borkel, Ángelo Santana Del Pino et al.

This study examines acute and delayed adverse reactions reported in naturalistic psychedelic use, focusing on their associations with substance-use patterns, contextual variables, and user motivations. Using an online survey incorporating the Psychedelic Use Scale, data were collected from a large naturalistic sample (N=1022) to analyze patterns of self-reported adverse reactions. Acute adverse...

[Anxiety-like behaviors induced by chronic administration of the synthetic cannabinoid 4F-ABUTINACA in rats and the underlying mechanisms].

Zhejiang da xue xue bao. Yi xue ban = Journal of Zhejiang University. Medical sciences September 25, 2026 Baobao Shi, Haitao Wang, Wenhua Zhou et al.

To elucidate the Δ9-tetrahydrocannabinol (THC)-like discrimina-tive stimulus effects of 4F-ABUTINACA and to investigate the potential mechanisms underlying anxiety-like behaviors induced by chronic 4F-ABUTINACA administration. A THC drug discrimination procedure was employed in six adult male Sprague-Dawley rats to assess the THC-like discriminative stimulus effects of 4F-ABUTINACA and to...
