Cannabinoids : the lows and the highs of chemotherapy-induced nausea and vomiting Toni Leigh Mortimer, Tom Mabin & Anna-Mart Engelbrecht Future Oncology, 2019 Doi : 10.2217/fon-2018-0530 Despite remaining one of the most widely abused drugs worldwide, Cannabis sativa exhibits remarkable medicinal properties. The phytocannabinoids, cannabidiol and -9-tetrahydrocannabinol, reduce nausea and vomiting, particularly during chemotherapy. This is attributed to their ability to reduce the release of serotonin from enterochromaffin cells in the small intestine, which would otherwise orchestrate the vomiting reflex. Although there are many preclinical and clinical studies on the effects of -9- tetrahydrocannabinol during nausea and vomiting, little is known about the role [...]

Comer and Margaret Haney Neuropsychopharmacology, 2018, 0, 1–10 Doi : 10.1038/s41386-018-0011-2 Cannabinoids combined with opioids produce synergistic antinociceptive effects, decreasing the lowest effective antinociceptive opioid dose (i.e., opioid-sparing effects) in laboratory animals. Although pain patients report greater analgesia when cannabis is used with opioids, no placebo-controlled studies have assessed the direct effects of opioids combined with cannabis in humans or the impact of the combination on abuse liability. This double-blind, placebo-controlled, within-subject study determined if cannabis enhances the analgesic effects [...]

Caldera SAGE Open Medical Case Reports, 2020, Volume 8, 1–3 DOI : 10.1177/2050313X20907015 Abstract Opioid medication–related deaths have increased to epidemic proportions in the last decade. This report describes a case of 43-year-old female with a traumatic brain injury who developed chronic pain and opioid dependence. The patient expressed concerns and wanted weaning off opioids. Recent legalization of medical marijuana in Pennsylvania allows us to try it as an alternative to opioids for chronic pain. Medical cannibus has risks associated with administration but is safer than opioids. Our patient [...]

Science/Homme: Le THC peut être utile dans le trouble de stress post-traumatique (IACM 30 mars 2020) Lors d’une étude contrôlée par placebo avec 71 participants, composée de 3 groupes (25 témoins sains, 27 adultes exposés à un traumatisme sans trouble de stress post-traumatique et 19 patients souffrant d'un trouble de stress post-traumatique), de faibles doses de THC ont réduit la réactivité liée à la menace dans une certaine [...]

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 [...]

Abstract and Introduction Background: Although cannabis is known to have cardiovascular and psychoactive effects, the implications of its use before surgery are currently unknown. The objective of the present study was to determine whether patients with an active cannabis use disorder have an elevated [...]

Doi : 10.1111/bph.14226 BACKGROUND AND PURPOSE Cannabidiol (CBD) represents a promising therapeutic tool for treating cannabis use disorder (CUD). This study aimed to evaluate the effects of CBD on the behavioural and gene expression alterations induced by spontaneous cannabinoid withdrawal. EXPERIMENTAL APPROACH Spontaneous cannabinoid withdrawal was evaluated 12 h after cessation of CP-55,940 treatment (0.5 mg·kg1 every 12 h, i.p.; 7 days) in C57BL/6J mice. The effects of CBD (5, 10 and 20 mg·kg1, i.p.) on withdrawal-related behavioural signs were evaluated by [...]
Lire la suiteCannabis is Not a Suitable Human Coronavirus Treatment Marc Moulin March 20, 2020 https://www.rxleaf.com/cannabis-not-good-human-coronavirus-treatment/ Using cannabis as a human coronavirus treatment may make symptoms worse. Cannabis is great for a lot of things. For example, many physical conditions see symptom abatement with cannabinoid treatment. Additionally, there is adequate, and in some cases, strong, scientific evidence to support consuming cannabis for therapeutic relief. Unfortunately, fighting off influenza-like viruses is not one of them. It’s important to note that there is absolutely no evidence to suggest that cannabis is an effective human coronavirus treatment. On the contrary, researchers from Michigan State University provide recent evidence to demonstrate potentially harmful [...]

Bosch, Erich Seifritz and Franz X. Vollenweider Frontiers in Pharmacology, 2017, Volume 8, Article 814, 1-9. Doi : 10.3389/fphar.2017.00814 Rationale : Stimulation of serotonin 2A (5-HT2A) receptors by lysergic acid diethylamide (LSD) and related compounds such as psilocybin has previously been shown to increase primary process thinking – an ontologically and evolutionary early, implicit, associative, and automatic mode of thinking which is typically occurring during altered states of consciousness such as dreaming. However, it is still largely unknown whether LSD induces [...]
