Therapeutic Satisfaction and Subjective Effects of Different Strains of Pharmaceutical-Grade Cannabis Tibor M. Brunt, Marianne van Genugten, Kathrin Honer-Snoeken, Marco J. van de Velde, and Raymond J.M. Niesink Journal of Clinical Psychopharmacoly, 2014, 34, 344Y349 Doi : 10.1097/JCP.0000000000000129 Abstract : In The Netherlands, pharmaceutical-grade cultivated cannabis is distributed for medicinal purposes as commissioned by the Ministry of Health. Few studies have thus far described its therapeutic efficacy or subjective (adverse) effects in patients. The aims of this study are to assess the therapeutic satisfaction within a group of patients using prescribed pharmaceutical-grade cannabis and to compare the subjective effects among the available strains with special [...]
Lire la suiteAcute and chronic effects of cannabinoids on effort-related decision-making and reward learning: an evaluation of the cannabis ‘amotivational’ hypotheses Will Lawn, Tom P. Freeman, Rebecca A. Pope, Alyssa Joye, Lisa Harvey, Chandni Hindocha, Claire Mokrysz, Abigail Moss, Matthew B. Wall, Michael A.P. Bloomfield, Ravi K. Das, Celia J.A. Morgan, David J. Nutt, H. Valerie Curran Psychopharmacology, 2016, 233, 3537–3552 Doi : 10.1007/s00213-016-4383-x Abstract Rationale : Anecdotally, both acute and chronic cannabis use have been associated with apathy, amotivation, and other reward processing deficits. To date, empirical support for these effects is limited, and no previous studies have assessed both acute effects of Δ-9-tetrahydrocannabinol (THC) and [...]

Effectiveness of tetrahydrocannabinol and cannabidiol inhibiting cell proliferation and epithelial mesenchymal transition in vitro Lara Milian, Manuel Mata, Javier Alcacer, Marıa Oliver, Marıa Sancho-Tello, Jose Javier Martın de Llano, Carlos Camps, Jose Galbis, Julian Carretero, Carmen Carda PLoS ONE, 2020, 15, (2): e0228909. Doi : 10.1371/journal.pone.0228909 Abstract Background/Objective : Patients with non-small cell lung cancer (NSCLC) develop resistance to antitumor agents by mechanisms that involve the epithelial-to-mesenchymal transition (EMT). This necessitates the development of new complementary drugs, e.g., cannabinoid receptors (CB1 and CB2) agonists including tetrahydro-cannabinol (THC) and cannabidiol (CBD). The combined use of THC and CBD [...]

Vega, Medscape, CME / ABIM MOC / CE Released : 12/13/2019 https://www.medscape.org/viewarticle/922367 Clinical Context The most common indication for the use of medicinal cannabis is pain, although the results of studies of cannabis products for chronic pain are mixed. Häuser and colleagues performed a review of systematic reviews of cannabis for chronic pain conditions, and their results were published in the October 15, 2017 issue of European Journal of Pain.[1] Reviewers evaluated 10 systematic reviews of cannabis for pain. Methodological quality was high in 4 of the reviews. There was [...]
Lire la suiteThe effects of cannabinoid 1 receptor compounds on memory : a meta-analysis and systematic review across species Faith Borgan, Katherine Beck, Emma Butler, Robert McCutcheon, Mattia Veronese, Anthony Vernon, Oliver D. Howes Psychopharmacology, 2019 Doi : 10.1007/s00213-019-05283-3 Abstract Rationale : While cannabis-based medicinal products have been shown to be effective for numerous neurological and psychiatric disorders, the evidence base regarding their adverse cognitive effects is poorly understood. The cannabinoid 1 receptor modulates memory performance via intracellular and extracellular mechanisms that alter synaptic transmission and plasticity. While previous literature has consistently shown that chronic cannabis users exhibitmarked cognitive impairments,mixed findings have been reported in the context [...]
Lire la suiteSpecies-specific susceptibility to cannabis-induced convulsions Benjamin J Whalley, Hong Lin, Lynne Bell, Thomas Hill, Amesha Patel, Roy A Gray, C Elizabeth Roberts, Orrin Devinsky, Michael Bazelot, Claire M Williams and Gary J Stephens British Journal of Pharmacology, 2018, 1-18. Doi : 10.1111/bph.14165 BACKGROUND AND PURPOSE Numerous claims are made for cannabis’ therapeutic utility upon human seizures, but concerns persist about risks. A potential confounder is the presence of both Δ9-tetrahydrocannabinol (THC), variously reported to be pro- and anticonvulsant, and cannabidiol (CBD), widely confirmed as anticonvulsant. Therefore, we investigated effects of prolonged exposure to different THC/CBD cannabis extracts on seizure activity and associated measures of endocannabinoid [...]

Doi : 10.3238/arztebl.2017.0627 SUMMARY Background : There are conflicting interpretations of the evidence regarding the efficacy, tolerability, and safety of cannabinoids in pain management and palliative medicine. Methods : We conducted a systematic review (SR) of systematic reviews of randomized controlled trials (RCT) and prospective long-term observational studies of the use of cannabinoids in pain management and palliative medicine. Pertinent publications from January 2009 to January 2017 were retrieved by a selective search in the Cochrane [...]

Joseph Brand and Zhongzhen Zhao Frontiers in Pharmacology, 2017, vol 8, Article 108, 1-11. doi : 10.3389/fphar.2017.00108 Cannabis sativa L. (Cannabaceae) has a long history of utilization as a fiber and seed crop in China, and its achenes (“seeds”) as well as other plant parts have been recorded in Chinese medical texts for nearly 2000 years. While the primary applications of cannabis in Chinese medicine center around the use of the achenes, ancient indications for the female inflorescence, and other plant parts include conditions such as pain [...]

The European Commission “Proposal for a Council Decision” is meaningful because – if adopted by the Council of Europe – the EU countries would vote as a block at the CND session in Vienna and the three motions [...]

The length of the side alkyl chain influences the biological activity of this cannabinoid. In particular, synthetic analogues of Δ9-THC with a longer side chain have shown cannabimimetic properties far higher than Δ9-THC [...]
