Le cannabis thérapeutique expérimenté 2 ans à partir de 2020, Par Public Sénat avec l’AFP, 12 juillet 2019

Le cannabis thérapeutique expérimenté 2 ans à partir de 2020 Par Public Sénat avec l'AFP Vendredi 12 juillet 2019 à 16:06 L’Agence du médicament a donné, jeudi, son accord à une expérimentation du cannabis thérapeutique. Sous l’impulsion d’Esther Benbassa, un débat sur la question avait eu lieu au mois de mai dans l’hémicycle. La sénatrice écologiste se réjouit de cette expérimentation mais regrette la « frilosité » du cadre. Fin 2018, l’Agence du médicament (ANSM) avait mandaté un comité d’experts (CSST) pour lui fournir un projet-cadre d’expérimentation du cannabis thérapeutique. Jeudi, l’ANSM a donc donné son feu vert aux conditions d’une expérimentation qui démarrera [...]

A Conversion of Oral Cannabidiol to Delta9-Tetrahydrocannabinol Seems Not to Occur in Humans, Gerhard Nahler et al., 2017

A Conversion of Oral Cannabidiol to Delta9-Tetrahydrocannabinol Seems Not to Occur in Humans Gerhard Nahler, Franjo Grotenhermen, Antonio Waldo Zuardi, and Jose´ A.S. Crippa3 Cannabis and Cannabinoid Research, 2017, 2, 1, 81-86 DOI: 10.1089/can.2017.0009 Abstract Cannabidiol (CBD), a major cannabinoid of hemp, does not bind to CB1 receptors and is therefore devoid of psychotomimetic properties. Under acidic conditions, CBD can be transformed to delta9 tetrahydro-cannabinol (THC) and other cannabinoids. It has been argued that this may occur also after oral administration in humans. However, the experimental conversion of CBD to THC and delta8-THC in simulated gastric fluid (SGF) is a highly artificial approach that deviates [...]

The Clinical Significance of Endocannabinoids in Endometriosis Pain Management, Jerome Bouaziz et al., 2017

The Clinical Significance of Endocannabinoids in Endometriosis Pain Management Jerome Bouaziz, Alexandra Bar On, Daniel S. Seidman, and David Soriano Cannabis and Cannabinoid Research, 2017, 2, 1, 72-80 DOI : 10.1089/can.2016.0035   Abstract Introduction : Patients with endometriosis often suffer from diffuse and poorly localized severe pain. The current pain management strategies include medical and hormonal therapy, as well as surgery. Medical management of pain is often insufficient and is associated with high rate of recurrence. Better pain management is therefore of urgent need. Methods : Among the various candidates, the endocannabinoid system (ECS) has recently emerged as a relevant pharmacological target for themanagement of endometriosis-related pain. [...]

How effective and safe is medical cannabis as a treatment of mental disorder ? A systematic review, Eva HOCH et al., 2019

How effective and safe is medical cannabis as a treatment of mental disorder ? A systematic review HOCH E., NIEMANN D., von KELLER R., SCHNEIDER M., FRIEMEL C.M., PREUSS U.W., HASAN A., POGARELL O. European Archives of Psychiatry and Clinical Neuroscience, 2019 https://doi.org/10.1007/s00406-019-00984-4   Abstract We conducted a review of systematic reviews (SRs) and randomized-controlled trials (RCTs) to analyze efficacy and safety of cannabis-based medication in patients with mental disorders. Five data bases were systematically searched (2006—August 2018); 4 SRs (of 11 RCTs) and 14 RCTs (1629 participants) were included. Diagnoses were: dementia, cannabis and opioid dependence, psychoses/schizophrenia, general social anxiety, posttraumatic stress disorder, anorexia nervosa, [...]

The diverse CB1 and CB2 receptor pharmacology of three plant cannabinoids : D9-tetrahydrocannabinol, cannabidiol and D9-tetrahydrocannabivarin, R.G. Pertwee, 2008

The diverse CB1 and CB2 receptor pharmacology of three plant cannabinoids : D9-tetrahydrocannabinol, cannabidiol and D9-tetrahydrocannabivarin Roger G. Pertwee British Journal of Pharmacology, 2008, 153, 199–215 doi:10.1038/sj.bjp.0707442   Cannabis sativa is the source of a unique set of compounds known collectively as plant cannabinoids or phytocannabinoids. This review focuses on the manner with which three of these compounds, (-)-trans-D9-tetrahydrocannabinol (D9-THC), (-)- cannabidiol (CBD) and (-)-trans-D9-tetrahydrocannabivarin (D9-THCV), interact with cannabinoid CB1 and CB2 receptors. D9-THC, the main psychotropic constituent of cannabis, is a CB1 and CB2 receptor partial agonist and in line with classical pharmacology, the responses it elicits appear to be strongly influenced both by [...]

Improved Social Interaction, Recognition and Working Memory with Cannabidiol Treatment in a Prenatal Infection (poly I:C) Rat Model, Ashleigh L. Osborne, 2017

Improved Social Interaction, Recognition and Working Memory with Cannabidiol Treatment in a Prenatal Infection (poly I:C) Rat Model Ashleigh L. Osborne, Nadia Solowij, Ilijana Babic, Xu-Feng Huang and Katrina Weston-Green Neuropsychopharmacology, 2017, 42, 1447–1457 0893-133X/17 www.neuropsychopharmacology.org doi:10.1038/npp.2017.40 Neuropsychiatric disorders such as schizophrenia are associated with cognitive impairment, including learning, memory and attention deficits. Antipsychotic drugs are limited in their efficacy to improve cognition; therefore, new therapeutic agents are required. Cannabidiol (CBD), the non-intoxicating component of cannabis, has anti-inflammatory, neuroprotective and antipsychotic-like properties; however, its ability to improve the cognitive deficits of schizophrenia remains unclear. Using a prenatal infection model, we examined the effect of chronic CBD [...]

Cannabinoïds and cancer: causation, remediation, and palliation, Wayne Hall et al., 2005

Cannabinoïds and cancer: causation, remediation, and palliation Wayne Hall, MacDonald Christie, David Currow Lancet Oncology, 2005, 6, 35–42 http://oncology.thelancet.com   This review discusses three different associations between cannabinoids and cancer. First, it assesses evidence that smoking of cannabis preparations may cause cancers of the aerodigestive and respiratory system. There have been case reports of upper-respiratory-tract cancers in young adults who smoke cannabis, but evidence from a few epidemiological cohort studies and case-control studies is inconsistent. Second, there is mixed evidence on the effects of THC and other cannabinoids on cancers: in some in vitro and in vivo studies THC and some synthetic cannabinoids have had [...]
