Cannabinoïdes synthétiques https://www.psychoactif.org/psychowiki/index.php?title=Cannabino%C3%AFdes_synth%C3%A9tiques   Les cannabinoïdes synthétiques sont des molécules de synthèse qui agissent d'une façon proche de celle des cannabinoïdes végétaux, naturellement présents dans le cannabis (comme le THC)[1]. Ce sont principalement des agonistes des récepteurs cannabinoïdes. La plupart ont été développés à des fins thérapeutiques (analgésie), d’autres ont été synthétisés dans le but de créer des alternatives légales au cannabis. Les cannabinoïdes synthètiques sont la classe la plus importante des nouveaux produits de synthèse. Sur les 73 nouvelles substances de synthèses reportées par le EMCDDA en 2012, 30 étaient des cannabinoïdes de synthèse. De 2008 à mai 2013, 84 cannabinoïdes de synthèse ont [...]

Pharmacokinetics and subjective effects of a novel oral LSD formulation in healthy subjects, Friederike Holze et al., 2019

Pharmacokinetics and subjective effects of a novel oral LSD formulation in healthy subjects Friederike Holze, Urs Duthaler, Patrick Vizeli, Felix Müller, Stefan Borgwardt, Matthias E. Liechti British Journal of Clinical Pharmacology, March 2019 Doi : 10.1111/bcp.13918   Aims : The aim of the present study was to characterize the pharmacokinetics and exposure–subjective response relationship of a novel oral solution of lysergic acid diethylamide (LSD) that was developed for clinical use in research and patients. Method : LSD (100 μg) was administered in 27 healthy subjects using a placebocontrolled, double‐blind, cross‐over design. Plasma levels of LSD, nor‐LSD, and 2‐ oxo‐3‐hydroxy‐LSD (O‐H‐LSD) and subjective drug effects were assessed [...]

Effect of D-9-Tetrahydrocannabinol and Cannabidiol on Nocturnal Sleep and Early-Morning Behavior in Young Adults, Anthony N. Nicholson et al., 2004

Effect of D-9-Tetrahydrocannabinol and Cannabidiol on Nocturnal Sleep and Early-Morning Behavior in Young Adults Anthony N. Nicholson, MD, PhD, Claire Turner, BSc, Barbara M. Stone, PhD, and Philip J. Robson, MDy Journal of Clinical Psychopharmacology, 2004, Volume 24, Number 3, 305-313. Doi : 10.1097/01.jcp.0000125688.05091.8f   Abstract : The effects of cannabis extracts on nocturnal sleep, earlymorning performance, memory, and sleepiness were studied in 8 healthy volunteers (4 males, 4 females; 21 to 34 years). The study was double-blind and placebo-controlled with a 4-way crossover design. The 4 treatments were placebo, 15 mg D-9-tetrahydro-cannabinol (THC), 5 mg THC combined with 5 mg cannabidiol (CBD), and 15 mg [...]

Mapping cannabis potency in medical and recreational programs in the United States, Mary Catherine Cash et al., 2020

Mapping cannabis potency in medical and recreational programs in the United States Mary Catherine Cash, Katharine Cunnane, Chuyin Fan, E. Alfonso Romero-Sandoval PLoS ONE, 2020, 15, (3), e0230167. Doi : 10.1371/journal.pone.0230167     Opinion d'expert: Les allégations sur l'infaisabilité du cannabis avec des concentrations élevées de THC à des fins médicales ne sont pas étayées par la science En mars 2020, le conseil d'administration de l'IACM a décidé d'installer une nouvelle catégorie dans le Bulletin de l’IACM, qui encourage à rédiger des opinions et des déclarations de chercheurs sur les rapports scientifiques actuels et des déclarations de collègues. Ces avis visent à stimuler la discussion sur [...]

MDMA-Induced Dissociative State not Mediated by the 5-HT2A Receptor, Drew J. Puxty et al., 2017

MDMA-Induced Dissociative State not Mediated by the 5-HT2A Receptor Drew J. Puxty, Johannes G. Ramaekers, Rafael de la Torre, Magí Farré, Neus Pizarro, Mitona Pujadas and Kim P. C. Kuypers Frontiers in Pharmacology, 2017, Volume 8, Article 455 Doi : 10.3389/fphar.2017.00455   Previous research has shown that a single dose of MDMA induce a dissociative state, by elevating feelings of depersonalization and derealization. Typically, it is assumed that action on the 5-HT2A receptor is the mechanism underlying these psychedelic experiences. In addition, other studies have shown associations between dissociative states and biological parameters (heart rate, cortisol), which are elevated by MDMA. In order to investigate [...]

Nonlinear Disposition and Metabolic Interactions of Cannabidiol Through CYP3A Inhibition In Vivo in Rats, Michiru Nagao et al., 2020

Nonlinear Disposition and Metabolic Interactions of Cannabidiol Through CYP3A Inhibition In Vivo in Rats Michiru Nagao, Yukako Nakano, Masataka Tajima, Erika Sugiyama, Vilasinee Hirunpanich Sato, Makoto Inada, and Hitoshi Sato Cannabis and Cannabinoid Research, 2020, Volume X, Number X, 1-8. DOI: 10.1089/can.2019.0098   Abstract Introduction : Cannabidiol (CBD) is known to affect the pharmacokinetics of other drugs through metabolic inhibition of CYP2C19 and CYP3A4. However, there is a lack of in vivo evidence for such drug interactions. Therefore, we investigated the saturability of CBD metabolism and CBD-drug interactions through inhibition of CYP3A in vivo. Materials and Methods : A nanoemulsion formulation of CBD (CBD-NE) was orally administered to [...]

L’huile de chanvre contient-elle du THC et du CBD ?, Newsweed, 11 février 2020, Aurélien BERNARD

L’huile de chanvre contient-elle du THC et du CBD ? Newsweed, 11 février 2020 Aurélien BERNARD https://www.newsweed.fr/huile-chanvre-contient-thc-cbd/   L’huile de chanvre, extraite des graines, est une source précieuse d’omega 3 et 6 et de nutriments dans l’alimentation quotidienne. Sa valeur nutritionnelle et thérapeutique pourrait néanmoins aussi être attribuée à sa composition en cannabinoïdes qui, si faiblement présents, existent quand même. Dans une étude de 2019, plusieurs cannabinoïdes ont été détectés dans l’huile de graines de chanvre et permettent de déterminer des différences dans leur composition chimique. Bien que le CBDA et le CBD soient prédominants dans les dix huiles étudiées, 20 autres cannabinoïdes «mineurs» ont été [...]

Comprehensive classification of USA cannabis samples based on chemical profiles of major cannabinoids and terpenoids, Ramia Z. Al Bakain et al., 2019

Comprehensive classification of USA cannabis samples based on chemical profiles of major cannabinoids and terpenoids Ramia Z. Al Bakain, Yahya S. Al-Degs, James V. Cizdziel and Mahmoud A. Elsohly Journal of Liquid Chromatography & Related Technologies, 2019 Doi : 10.1080/10826076.2019.1701015   ABSTRACT Different USA-origin cannabis samples were analyzed by GC-FID to quantify all possible cannabinoids and terpenoids prior to their clustering. Chromatographic analysis confirmed the presence of seven cannabinoids and sixteen terpenoids with variable levels. Among tested cannabinoids, D9-Tetrahydro-cannabinol D9-THC and cannabinol CBN were available in excess amounts (1.2–8.0 wt%) and (0.22–1.1 wt%), respectively. Fenchol was the most abundant terpenoid with a range of (0.03–1.0 wt%). [...]

Intensity of Mystical Experiences Occasioned by 5-MeO-DMT and Comparison With a Prior Psilocybin Study, Joseph Barsuglia et al., 2018

Intensity of Mystical Experiences Occasioned by 5-MeO-DMT and Comparison With a Prior Psilocybin Study Joseph Barsuglia, Alan K. Davis, Robert Palmer, Rafael Lancelotta, Austin-Marley Windham-Herman, Kristel Peterson, Martin Polanco, Robert Grant and Roland R. Griffiths Frontiers in Psychology, 2018, Vol 9, Article doi : 10.3389/fpsyg.2018.02459   5-MeO-DMT is a psychoactive substance found in high concentrations in the bufotoxin of the Colorado River Toad (Bufo alvarius). Emerging evidence suggests that vaporized 5-MeO-DMT may occasion mystical experiences of comparable intensity to those occasioned by more widely studied psychedelics such as psilocybin, but no empirical study has tested this hypothesis. Data was obtained from 20 individuals (Mage = [...]

Psychedelics and potential benefits in “healthy normals”: A review of the literature, Sam GANDY, 2019

Psychedelics and potential benefits in “healthy normals”: A review of the literature Sam GANDY Journal of Psychedelic Studies, 2019, 3, (3), 280–287. Doi : 10.1556/2054.2019.029   We are in the midst of a psychedelic research renaissance. With research examining the efficacy of psychedelics as a treatment for a range of mental health indications still in its early stages, there is an increasing body of research to show that careful use of psychedelics can yield a variety of benefits in “healthy normals” and so lead to “the betterment of well people.” Psychedelics have been found to modulate neuroplasticity, and usage in a supportive setting can result [...]
