Synthetic cannabinoids and potential cardiac arrhythmia risk : an important message for drug users Jules C. Hancox, Nicola J. Kalk and Graeme Henderson Therapeutic Advances in Drug Safety, 2020, 11, 1-4. Doi : 10.1177/2042098620913416 Δ9-Tetrahydrocannabinol, the psychoactive ingredient in cannabis, and synthetic cannabinoid receptor agonists (SCRAs) activate the CB1 receptor to produce their profound behavioural effects and are widely used as recreational drugs. There is growing evidence that SCRAs, commonly known by the street name Spice or K2 (though there are many others, see: http://www.emcdda.europa.eu/publications/drug-profiles/synthetic-cannabinoids) can produce detrimental cardiovascular effects.(1) Commonly observed cardiotoxic effects of SCRAs include tachycardia, chest pain and hypertension.(1) However, bradycardia and [...]

Ils désignent un éventail très hétérogène de substances qui imitent les effets de différents produits illicites (ecstasy, amphétamines, cocaïne, cannabis, etc.). Leurs structures moléculaires s’en rapprochent, sans être tout à fait identiques. Cette spécificité leur permet, au moins à court terme, de contourner la législation sur les stupéfiants ; certains sont classés, d’autres n’ont pas de statut juridique clair. Généralement achetés sur Internet, les NPS sont connus soit par leurs noms [...]

Tallon JOURNAL OF DIETARY SUPPLEMENTS, 2020, VOL. 17, NO. 5, 503–516 Doi : 10.1080/19390211.2020.1795044 ABSTRACT The lawful sale of Cannabis sativa L. and its extracts including Cannabidiol is not harmonized under European Union (EU) law. Such products have in the most part been classified as novel foods and thus illegal for sale in Europe without prior authorization. The regulation of such substances not only spans EU and Member State food laws but also international conventions on illicit drug and psychoactive substances. An understanding of the laws [...]

Quelques instants après leur consommation, les usagers ont ressenti des effets indésirables totalement inhabituels comme des picotements sur la langue, des troubles de la vision, des pertes d’équilibre, des vomissements, de la tachycardie voire des sensations d’étouffement. Nous avons alors organisé la [...]
Lire la suiteCirculation d’herbe de cannabis adultérée avec des cannabinoïdes de synthèse Victor Detrez - Magali Martinez Note SINTES - Octobre 2020, 2 p. Depuis l’été 2019, plusieurs pays européens ont observé la circulation de résine et d’herbe de cannabis très faiblement dosées en Δ-9-tetrahydrocannabinol (THC), avec ou non du cannabidiol (CBD), adultérées avec des cannabinoïdes de synthèse (Autriche, Suisse)1. Ces produits sont vendus de façon trompeuse comme du simple cannabis. En France, ce phénomène a été rapporte par plusieurs associations (en Provence-Alpes-Côte d’Azur et Bourgogne-Franche-Comte), sans qu’il y ait eu des analyses sur le territoire français jusqu’à maintenant. Ces herbes ou résines ont un [...]

Hutson Psychiatry Research, 2020, 284, 112749 Doi : 10.1016/j.psychres.2020.112749 A B S T R A C T The current meta-analysis examined the effects of psilocybin in combination with behavioral interventions on anxiety and depression in samples with elevated symptoms. Across four studies (one uncontrolled; three randomized, placebo-controlled; N = 117), within-group pre-post and pre-follow-up effects on anxiety and depression were large (Hedges’ gs=1.16 to 1.47) and statistically significant. Across three placebo-controlled studies, pre-post placebo-controlled effects were also [...]
