Cannabis use and mental health : risks and benefits, Wayne HALL et al., 2019

Cannabis use and mental health: risks and benefits Wayne HALL, · Eva HOCH, · Valentina LORENZETTI European Archives of Psychiatry and Clinical Neuroscience, february 2019 https://doi.org/10.1007/s00406-019-00986-2 © Springer-Verlag GmbH Germany, part of Springer Nature 2019   In public debates about cannabis policy, two competing claims are often made about how cannabis use may affect mental health. One is that cannabis use by young adults and vulnerable individuals across the lifespan can be a contributory cause of : a cannabis dependence syndrome; schizophreniform psychoses; anxiety and depressive disorders; acute and perhaps chronic cognitive impairment, and structural and functional changes in brain pathways implicated in reward, learning and [...]

The Role of CB2 Receptor in the Recovery of Mice after Traumatic Brain Injury, Lital MAJID et al., 2018

The Role of CB2 Receptor in the Recovery of Mice after Traumatic Brain Injury Lital MAJID, Sami HEYMAN, Merav ELGALI ... Esther SHOHAMI et al. Journal of Neurotrauma, Nov 2018, 36, 1-11 DOI: 10.1089/neu.2018.6063   Abstract : Cannabis is one of the most widely used plant drugs in the world today. In spite of the large number of scientific reports on medical marijuana, there still exists much controversy surrounding its use and the potential for abuse due to the undesirable psychotropic effects. However, recent developments in medicinal chemistry of novel non-psychoactive synthetic cannabinoids have indicated that it is possible to separate some of the therapeutic effects [...]

Cultural Neurophenomenology of Psychedelic Thought : Guiding the “Unconstrained” Mind Through Ritual Context, Michael LIFSHITZ et al., 2018

Cultural Neurophenomenology of Psychedelic Thought: Guiding the “Unconstrained” Mind Through Ritual Context Michael LIFSHITZ, Eli SHEINER, and Laurence J. KIRMAYER The Oxford Handbook of Spontaneous Thought : Mind-Wandering, Creativity, and Dreaming Edited by Kalina Christoff and Kieran C.R. Fox, avril 2018   Abstract : This chapter explores psychedelics as catalysts of spontaneous thought. Classic serotonergic psychedelics such as psilocybin, LSD, and ayahuasca can induce potent alterations in cognition and perception. The chapter reviews research on these substances through the lens of cultural neurophenomenology, which aims to trace how neurobiology and sociocultural factors interact to shape experience. After a decades-long hiatus, the scientific study of psychedelics is rediscovering [...]

The neurobiology of addiction, George R. Uhl et al., 2019

The neurobiology of addiction George R. Uhl, George F. Koob, and Jennifer Cable ANNALS OF THE NEW YORK ACADEMY OF SCIENCES, 2019 Special Issue: Addiction Reviews https://doi.org/10.1111/nyas.13989 Substance and alcohol use disorders impose large health and economic burdens on individuals, families, communities, and society. Neither prevention nor treatment efforts are effective in all individuals. Results are often modest. Advances in neuroscience and addiction research have helped to describe the neurobiological changes that occur when a person transitions from recreational substance use to a substance use disorder or addiction. Understanding both the drivers and consequences of substance use in vulnerable populations, including those whose brains are [...]

Medicinal cannabis – Potential Drug Interactions, M.A. Alsherbiny, C. Guang Li, décembre 2018

Medicinal cannabis - Potential Drug Interactions M.A. Alsherbiny, C. Guang Li, décembre 2018. www.preprints.org,  doi:10.20944/preprints201812.0032.v1   https://www.researchgate.net/publication/329559938_Medicinal_Cannabis_-_Potential_Drug_Interactions   Endocannabinoids system (ECS) engrossed a considerable interest as potential therapeutic targets in various carcinomas and cancer related conditions alongside with neurodegenerative diseases. Cannabinoids are implemented in several physiological processes such as appetite stimulation, energy balance, pain modulation and the control of chemotherapy induced nausea and vomiting (CINV). However, pharmacokinetics and pharmacodynamics interactions could be perceived in drug combinations, so in this short review we tried to shed the light over the potential drug interactions of medicinal cannabis. Hitherto, few data have been provided to the healthcare practitioners about [...]

Les méta-analyses et le cannabis, ou la négation du savoir clinique, 21 Septembre 2011, Dr. Christian Sueur,

Les méta-analyses et le cannabis, ou la négation du savoir clinique 21 Septembre 2011 Dr. Christian Sueur, Psychiatre, praticien hospitalier http://tdme.free.fr/?p=2730#annot8   A l’ère des méta-analyses, la clinique psychiatrique bat de l’aile…., Ce que l’on peut lire aujourd’hui sur les « dangers du cannabis » fournit un exemple étonnant de cette perte du savoir clinique. Et pourtant, bien des « méta-analystes » qui parfois, n’ont jamais vu un patient, sans vergogne, « disent le vrai », et emportent l’opinion avec eux, opinion et journalistes qui se font l’écho de ses assertions, sans même émettre la moindre critique vis-à-vis de ces « chiffres » érigés en « [...]

Antidepressive-like effect induced by Cannabidiol is dependent on brain serotonine levels, A.J. Sales et al., 2018

Antidépresseur-like effect induced by Cannabidiol is dependent on brain serotonin levels. A.J. Sales, C. C. Crestani, F. S. Guimaraes, S. R.L. Joca, Progress in Neuropsychopharmacology & Biological Psychiatry, 2018 Aug 30; 86: 255-261. Doi: 10.1016/j.pnpbp.2018.06.002 https://www.ncbi.nlm.nih.gov/pubmed/29885468 PMID : 29885468 Abstract Cannabidiol (CBD) is a compound of Cannabis sativa with relevant therapeutic potential in several neuropsychiatric disorders including depression. CBD treatment has shown significant antidepressant-like effects in different rodent preclinical models. However, the mechanisms involved in CBD-induced antidepressant effects are still poorly understood. Therefore, this work aimed at investigating the participation of serotonin (5-HT) and/or noradrenaline (NA) in CBD-induced antidepressant-like effects in [...]
