THCp – Newly discovered and highly potent phytocannabinoid, cannabislifenetwork.com, 2020

THCp – Newly discovered and highly potent phytocannabinoid Source : cannabislifenetwork.com Publié le 1 Fév 2020 We have discovered so much about cannabis over the years, but it’s vast, intricate, pharmacological map is missing many major regions. CBD dominant varieties have exploded in demand, yet the cannabinoid is still only partially understood, and there is still CBG and CBN just around the market’s corner. Now, brand new forms of THC and CBD, THCp and CBDp, respectively, have been discovered; evidence that the map’s expanse is still beyond our grasp. Phytocannabinoids over synthetics Lately, stories of newly discovered cannabinoids are strewn with the accomplishments of a biochemist [...]

Un nouveau phytocannabinoïde isolé du Cannabis sativa L avec une activité cannabimimétique 30 fois supérieure au THC a été détecté dans le cannabis, blog-cannabis.fr, 2019

Un nouveau phytocannabinoïde isolé du Cannabis sativa L avec une activité cannabimimétique 30 fois supérieure au THC a été détecté dans le cannabis Source : blog-cannabis.fr 31 décembre 2019 https://www.blog-cannabis.fr/2019/12/31/thcp-nouveau-cannabinoide/ (transmis par les amis de Principesactifs.org) https://www.principesactifs.org/le-thcp-un-nouveau-cannabinoide-33-fois-plus-fort-que-le-thc/   Le cannabinoïde végétal Tetrahydrocannabiphorol ( THCP ) le plus puissant au monde a récemment été découvert dans une étude en Italie. Il est presque identique dans sa structure au THC mais est 33 fois plus fort que lui, ainsi que du CBDP, le dérivé correspondant du CBD. La recherche pourrait permettre de développer de futures souches de THCP beaucoup plus puissantes. Jusqu’à présent, près de 150 phytocannabinoïdes ont été détectés dans la plante de cannabis, bien que [...]

The current state and future perspectives of cannabinoids in cancer biology, Paweł Śledziński et al., 2018

The current state and future perspectives of cannabinoids in cancer biology Paweł Śledziński, Joanna Zeyland, Ryszard Słomski & Agnieszka Nowak Cancer Medicine, 2018, 7, (3), 765–775. doi : 10.1002/cam4.1312   Abstract To date, cannabinoids have been allowed in the palliative medicine due to their analgesic and antiemetic effects, but increasing number of preclinical studies indicates their anticancer properties. Cannabinoids exhibit their action by a modulation of the signaling pathways crucial in the control of cell proliferation and survival. Many in vitro and in vivo experiments have shown that cannabinoids inhibit proliferation of cancer cells, stimulate autophagy and apoptosis, and have also a potential to inhibit angiogenesis [...]

Les troubles cognitifs et psychiatriques liés à la consommation de cannabis, Alain DERVAUX, 2014

Les troubles cognitifs et psychiatriques liés à la consommation de cannabis Alain DERVAUX, Marie-Odile KREBS , Xavier LAQUEILLE Bulletin de l'Académie Nationale de Médecine, 2014, 198, no 3, 559-577, séance du 25 mars 2014   RÉSUMÉ Plusieurs études ont montré que le Δ-9-THC, principal principe actif du cannabis entraînait des troubles de l’attention, de la mémoire et des fonctions exécutives. Ils sont liés à la dose, à la fréquence, à la durée d’exposition et à l’âge de la première consommation. Ils peuvent disparaître après sevrage, mais des anomalies durables s’observent chez les sujets ayant débuté leur consommation avant l’âge de 15 ans. La fréquence de [...]

6 variétés de cannabis pleines de THCV, Aurélien BERNARD, Newsweed.fr, 30 janvier 2020

6 variétés de cannabis pleines de THCV Aurélien BERNARD Newsweed.fr, 30 janvier 2020 https://www.newsweed.fr/5-varietes-cannabis-thcv/ À mesure que les connaissances scientifiques sur le cannabis se développent, la composition chimique du cannabis et la manière dont il interagit avec le corps se dévoilent. Et si le CBD ou le THC sont largement étudiés, certains cannabinoïdes plus rares comme le THCV (tetrahydocannabivarine) intéressent de plus en plus les scientifiques. Au cours de la dernière décennie, des études sur des humains et des animaux ont identifié le potentiel du THCV pour réduire l’appétit chez les personnes qui luttent pour perdre du poids, réguler la glycémie chez les personnes atteintes [...]

Medicinal cannabis for psychiatric disorders: a clinically-focused systematic review, Jerome Sarris et al., 2020

Medicinal cannabis for psychiatric disorders: a clinically-focused systematic review Jerome Sarris, Justin Sinclair, Diana Karamacoska, Maggie Davidson and Joseph Firth BMC Psychiatry, 2020, 20, 24, 1-14. Doi : 10.1186/s12888-019-2409-8   Abstract Background : Medicinal cannabis has received increased research attention over recent years due to loosening global regulatory changes. Medicinal cannabis has been reported to have potential efficacy in reducing pain, muscle spasticity, chemotherapy-induced nausea and vomiting, and intractable childhood epilepsy. Yet its potential application in the field of psychiatry is lesser known. Methods : The first clinically-focused systematic review on the emerging medical application of cannabis across all major psychiatric disorders was conducted. Current evidence regarding [...]

Psilocybin Benefits in Cancer Sustained Nearly 5 Years Later, Nancy A. Melville, 2020

Psilocybin Benefits in Cancer Sustained Nearly 5 Years Later Nancy A. Melville Medscape, January 28, 2020 Medscape Medical News © 2020 Cancer patients who were treated with a one-time, single dose of the psychedelic drug psilocybin, combined with psychotherapy, showed significant benefits on measures of emotional and existential distress nearly 5 years after receiving the therapy, new research indicates. In addition to reporting improved well-being or life satisfaction, some patients rated the treatment as being "among the most personally meaningful and spiritually significant experiences of their lives," the authors note. The study, the longest-spanning evaluation to date of the effects of psilocybin in the treatment of cancer-related psychiatric distress, was [...]

Psychological Explorations of the Magic Mushroom (Psilocybin) Experience, Part I : Subjective Effects and Time Passage Perception, José Arturo Costa Escobar & Antonio Roazzi, 2011

Psychological Explorations of the Magic Mushroom (Psilocybin) Experience, Part I : Subjective Effects and Time Passage Perception José Arturo Costa Escobar, M.S., Antonio Roazzi, Ph.D. Neurobiologia, 2011, 74, (3-4), 81-97.   ABSTRACT Magic mushrooms are rich in the active compound psilocybin, whose activity on consciousness deeply alters cognitive functions, can promote spiritual/mystical experiences and has high biomedical and psychotherapeutic importance. Twenty-eight participants underwent a magic mushroom experience after consuming dehydrated Psilocybe cubensis mushrooms at the dosage of 55.6 mg/Kg (350 μg/kg of psilocybin). Results of subjective aspects of the experience through the Hallucinogen Rating Scale revealed equivalent dosage effects comparable to other studies and similar [...]

“Go Ask Alice”: The Case for Researching Schedule I Drugs, Kenneth V. ISERSON , 2019

“Go Ask Alice”: The Case for Researching Schedule I Drugs Kenneth V. ISERSON Cambridge Quarterly of Healthcare Ethics, 2019, 28, 168–177. © Cambridge University Press 2018. doi : 10.1017/S0963180118000518   Abstract : The available treatments for disorders affecting large segments of the population are often costly, complex, and only marginally effective, and many have numerous side effects. These disorders include dementias, debilitating neurological disorders, the multiple types of drug addiction, and the spectrum of mental health disorders. Preliminary studies have shown that a variety of psychedelic and similar U.S. Drug Enforcement Administration Schedule I drugs may offer better treatment options than those that currently exist and pose potentially [...]

A tale of two cannabinoids : The therapeutic rationale for combining tetrahydrocannabinol and cannabidiol, Ethan Russo & Geoffrey W. Guy, 2006

A tale of two cannabinoids : The therapeutic rationale for combining tetrahydrocannabinol and cannabidiol Ethan Russo & Geoffrey W. Guy Medical Hypotheses, 2006, 66, 234–246 doi : 10.1016/j.mehy.2005.08.026 Summary This study examines the current knowledge of physiological and clinical effects of tetrahydrocannabinol (THC) and cannabidiol (CBD) and presents a rationale for their combination in pharmaceutical preparations. Cannabinoid and vanilloid receptor effects as well as non-receptor mechanisms are explored, such as the capability of THC and CBD to act as anti-inflammatory substances independent of cyclo-oxygenase (COX) inhibition. CBD is demonstrated to antagonise some undesirable effects of THC including intoxication, sedation and tachycardia, while contributing analgesic, anti-emetic, [...]
