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 [...]

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 [...]

Cannabis thérapeutique : en avant vers l'expérimentation Par Charles Delouche, Libération, — 28 juin 2019 à 18:36 Après un an d'études, le comité scientifique spécialisé a rendu son avis définitif sur la mise en place du cannabis thérapeutique en France. La balle est désormais dans le camp de l'Agence du médicament et de la Direction générale de la santé. Cannabis thérapeutique : en avant vers l'expérimentation Dévoilé avant même la fin du cycle des auditions le mercredi 19 juin, le projet final d’expérimentation du cannabis à visée thérapeutique a été dans l’ensemble favorablement accueilli par les associations de patients. Elles étaient [...]

"Biology, Pharmacology, Diagnosis, and Treatment", 2017, Pages 939-946 https://doi.org/10.1016/B978-0-12-800756-3.00113-7 Abstract The problematic use of psychoactive substances like alcohol, cannabis, cocaine, amphetamines, heroin, and nicotine carry a series of health, economic, and social costs to individuals and society. Although pharmacological treatments for alcohol, heroin, and nicotine abuse or dependence are available, there is no approved medication for the treatment of cannabis and stimulant dependence. Cannabidiol (CBD), a nonpsychotomimetic cannabinoid present in the cannabis plant, has anxiolytic, antipsychotic, antiepileptic, [...]

Phillips Cannabis and Cannabinoid Research, 2018, 3, 1, 152-161. https://doi.org/10.1089/can.2018.0006 Abstract Introduction: Preclinical and clinical studies suggest that cannabidiol (CBD) found in Cannabis spp. has broad therapeutic value. CBD products can currently be purchased online, over the counter and at Cannabis-specific dispensaries throughout most of the country, despite the fact that CBD is generally deemed a Schedule I controlled substance by the U.S. Drug Enforcement Administration and renounced as a dietary supplement ingredient by the U.S. Food and Drug Administration. Consumer demand for CBD is high and growing, but few studies have examined the [...]

We would like to share our views on the role of CBD in the prevention and treatment of movement disorders. CBD is one of the main components of Cannabis sativa investigated previously for its neuroprotective effects. Its mechanism of action [...]

Reggio Progress in the Chemistry of Organic Natural Products, 2017 ; 103: 103–131. doi:10.1007/978-3-319-45541-9_4. 1 Introduction For centuries, hashish and marihuana, both derived from the Indian hemp Cannabis sativa L., have been used for their medicinal, as well as, their psychotropic effects. Phytocannabinoids are oxygen containing C21 aromatic hydrocarbons found in Cannabis sativa L. To date, over 120 phytocannabinoids have been isolated from Cannabis, including two compounds, (−)-trans-Δ9-tetrahydrocannabinol (Δ9-THC) and (−)-trans-Δ8-THC (Δ8-THC) that have been shown to bind to cannabinoid receptors and elicit the characteristic psychotropic effect associated with Cannabis [1].

Anthropological perspectives on the self-administration of high potency cannabis in the UK Anna Waldstein Drugs and Alcohol Today • Volume 10 Issue 3 • September 2010 Abstract Domestically produced, high potency cannabis (often referred to as ‘skunk’ in the mainstream UK media) has become increasingly widespread in the UK. This paper considers whether the trend reflects an increased awareness of and desire for medical marijuana. Determining whether cannabis is a drug or a medicine depends on its objective physiological effects – which may vary from one individual to another – as well as how and why those effects are experienced. The [...]
