Effects of CBD-Enriched Cannabis sativa Extract on Autism Spectrum Disorder Symptoms : An Observational Study of 18 Participants Undergoing Compassionate Use Paulo Fleury-Teixeira, Fabio Viegas Caixeta, Leandro Cruz Ramires da Silva, Joaquim Pereira Brasil-Neto and Renato Malcher-Lopes Frontiers in Neurology, October 2019, Volume 10, Article 1145 doi : 10.3389/fneur.2019.01145 Autism Spectrum Disorders comprise conditions that may affect cognitive development, motor skills, social interaction, communication, and behavior. This set of functional deficits often results in lack of independence for the diagnosed individuals, and severe distress for patients, families, and caregivers. There is a mounting body of evidence indicating the effectiveness of pure cannabidiol (CBD) and [...]

The use of complementary medicine such as medicinal cannabis in search for a potential treatment or cure is common in ALS. Preclinical studies have demonstrated the efficacy [...]

Rushlow and Steven R. Laviolette The Journal of Neuroscience, 2019 https://doi.org/10.1523/JNEUROSCI.0708-19.2019 Abstract Evidence suggests that the phytocannabinoids Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) differentially regulate salience attribution and psychiatric risk. The ventral hippocampus (vHipp) relays emotional salience via control of dopamine (DA) neuronal activity states, which are dysregulated in psychosis and schizophrenia. Using in-vivo electrophysiology in male Sprague Dawley rats, we demonstrate that intra-vHipp THC strongly increases ventral tegmental area (VTA) DA neuronal frequency and bursting rates, decreases GABA frequency, and [...]

Lee On February 22, 2015 https://www.projectcbd.org/science/cbd-isolates-vs-full-spectrum-cbd A groundbreaking study has documented the superior therapeutic properties of whole plant CBD-rich cannabis extract as compared to single-molecule CBD. A groundbreaking study from Israel has documented the superior therapeutic properties of whole plant CBD-rich cannabis extract as compared to single-molecule cannabidiol (CBD). Published in the journal Pharmacology & Pharmacy (Feb. 2015), the article directly challenges one of the sacred cows of Big Pharma and the medical-industrial complex—the notion that “crude” botanical preparations are inherently low grade and less effective than pure, single-molecule compounds. Entitled “Overcoming the Bell-Shaped Dose-Response of Cannabidiol by Using Cannabis [...]

Lee On February 09, 2017 Originally published in High Times (Feb. 2017) https://www.projectcbd.org/culture/cbd-cinderella-molecule High Times cover story by Martin A Lee highlights the breakthrough research on CBD, and how it has revolutionized the story of cannabis medicine. “This changes everything!” That was the immediate reaction of Bay Area journalist Fred Gardner as he stood in the office of Steep Hill Laboratory in Oakland and eyed a chromatogram showing the unusual cannabinoid content of a hitherto unknown marijuana strain. The year was 2009, and the strain of interest, an oddity called Soma A-Plus, didn’t top the charts with THC (tetrahydrocannabinol), [...]

A Beginner’s Guide to CBD & Cannabis Therapeutics In 2009, a handful of CBD-rich cannabis strains were discovered serendipitously in Northern California, America’s cannabis breadbasket, where certified patients could access medical marijuana legally. Thus began a great laboratory experiment in democracy involving CBD-rich cannabis therapeutics. The advent of whole plant CBD-rich oil as a grassroots therapeutic option has changed the national conversation about cannabis. It’s no longer a question of whether [...]

Goudriaan and Wim van den Brink Harm Reduction Journal, 2018, 15, 47, 1-4. Doi : 10.1186/s12954-018-0253-7 Abstract Background : Cannabis-smoking patients with a psychotic disorder have poorer disease outcomes than non-cannabis-smoking patients with poorest outcomes in patients smoking high-potency cannabis (HPC) containing high Δ9-tetrahydrocannabinol (THC) and low cannabidiol (CBD). Quitting cannabis smoking or substitution of HPC by cannabis variants containing less THC and/or more CBD may benefit these patients. The present study explores whether daily HPC-smoking patients with schizophrenia accept smoking [...]
Lire la suiteUsing CBD to tame a cannabis high? Small doses may have opposite effect Bailey Rahn February 28, 2019 Share Print (imaginima/iStock) Take some CBD, they said. You’ll feel less high, they said. This common piece of advice fed to THC-shy consumers can effectively bring someone back down to earth. It works—sometimes. But new research shows there’s likely more nuance in the solution than we initially thought. Scientists found that a high dose of CBD dampened the effects of a THC high, but participants reported a stronger high when combined with low doses of CBD. CBD can either dampen an out-of-control high [...]

Hall, Michael Farrell, Louisa Degenhardt Lancet Psychiatry, 2019 https://doi.org/10.1016/S2215-0366(19)30401-8 Summary Background : Medicinal cannabinoids, including medicinal cannabis and pharmaceutical cannabinoids and their synthetic derivatives, such as tetrahydrocannabinol (THC) and cannabidiol (CBD), have been suggested to have a therapeutic role in certain mental disorders. We analysed the available evidence to ascertain the effectiveness and safety of all types of medicinal cannabinoids in treating symptoms of various mental disorders. Methods : For this systematic review and meta-analysis [...]
