“Treatment with a highly purified oral solution of cannabidiol (CBD), derived from the plant Cannabis sativa L., demonstrated some evidence of central nervous system (CNS)-related adverse events in patients enrolled in phase 3 trials for treatment of childhood-onset epilepsy. Cannabidiol was categorized as a Schedule 1 substance by the United States Drug Enforcement Administration; therefore, it was important to test CBD for human abuse potential.
Administration of a therapeutic dose of CBD (750 mg) showed significantly low abuse potential in a highly sensitive population of polydrug users. Although high and supratherapeutic doses of CBD (1500 mg and 4500 mg, respectively) had detectable subjective effects compared with placebo; the effects were significantly lower than those observed with alprazolam and dronabinol.Tag Archives: cannabidiol
New Perspectives on the Use of Cannabis in the Treatment of Psychiatric Disorders.
“Following the discovery of the endocannabinoid system and its potential as a therapeutic target for various pathological conditions, growing interest led researchers to investigate the role of cannabis and its derivatives for medical purposes. The compounds Δ9-tetrahydrocannabinol and cannabidiol are the most abundant phytocannabinoids found in cannabis extracts, as well as the most studied. The present review aims to provide an overview of the current evidence for their beneficial effects in treating psychiatric disorders, including schizophrenia, anxiety, and depression. Nevertheless, further investigations are required to clarify many pending issues, especially those relative to the assessment of benefits and risks when using cannabis for therapeutic purposes, thereby also helping national and federal jurisdictions to remain updated.”

Report of Objective Clinical Responses of Cancer Patients to Pharmaceutical-grade Synthetic Cannabidiol.
“Cannabinoids are widely used in the management of pain, nausea and cachexia in cancer patients. However, there has been no objective clinical evidence of any anticancer activity yet. The aim of this study was to assess the effects of pharmaceutical-grade synthetic cannabidiol on a range of cancer patients.
RESULTS:
Clinical responses were seen in 92% of the 119 cases with solid tumours including a reduction in circulating tumour cells in many cases and in other cases, a reduction in tumour size, as shown by repeat scans. No side-effects of any kind were observed when using pharmaceutical grade synthetic cannabidiol.CONCLUSION:
Pharmaceutical-grade synthetic cannabidiol is a candidate for treating breast cancer and glioma patients.” https://www.ncbi.nlm.nih.gov/pubmed/30275207 http://ar.iiarjournals.org/content/38/10/5831]]>Repeated Cannabidiol treatment reduces cocaine intake and modulates neural proliferation and CB1R expression in the mouse hippocampus.
“Cannabinoid derivatives have shown promising results for treating neuropsychiatric disorders, including drug addiction.
Recent studies on the therapeutic effects of Cannabidiol (CBD) on drug abuse showed mixed results, especially with psychostimulant substances such as cocaine. To determine whether CBD can attenuate cocaine reinforcement, we assessed behavioural responses induced by cocaine in mice, using the behavioural sensitization, conditioned place preference and intravenous self-administration paradigms.
We show that repeated CBD treatment produces anxiolytic effects in the elevated plus maze test, increases the discrimination index of the novel object recognition task and attenuates cocaine-induced conditioned place preference but does not affect behavioural sensitization.
CBD reduced cocaine voluntary consumption and progressive ratio breaking point in the self-administration paradigm, but not drug-induced reinstatement. In parallel, CBD increased expression of type 1 cannabinoid receptor, MAPK-CREB phosphorylation, BDNF expression, and neural cell proliferation in the hippocampus, and reduced the GluA1/2 AMPA subunit receptor ratio in the striatum.
In summary, we show that CBD can modulate some behavioural and molecular manifestations of cocaine reinforcement. Moreover, our findings show that CBD has pro-neurogenic effects also in cocaine consuming animals.
Overall, this novel evidence provides new perspectives to use CBD as a therapeutic tool.”

“This meta-analysis paper describes the analysis of observational clinical studies on the treatment of refractory epilepsy with cannabidiol (CBD)-based products. Beyond attempting to establish the safety and efficacy of such products, we also investigated if there is enough evidence to assume any difference in efficacy between CBD-rich extracts compared to purified CBD products.
The systematic search took place in February/2017 and updated in December/2017 using the keywords “epilepsy” or “Dravet” or “Lennox-Gastaut” or “CDKL5” combined with “Cannabis,” “
“Both Δ9 Tetrahydrocannabidiol (THC) and cannabidiol (CBD) components of cannabis, have been shown to have anticonvulsant effects.
Cannabis oils are used to treat seizures in drug-resistant epilepsy (DRE). Recent trials provide data on dosing, side effects, and efficacy of CBD, yet there is a paucity of information on THC in epilepsy.
Primary objective was to establish dosing and tolerability of TIL-TC150 – a cannabis plant extract produced by Tilray®, containing 100 mg/mL CBD and 2 mg/mL THC- in children with Dravet syndrome. Secondary objectives were to assess impact of therapy on seizures, electroencephalogram (EEG) and quality of life.
“Multiple sclerosis (MS) is a complex disease with a heterogeneous and unpredictable clinical course. Mobility impairment after progressive paralyses and muscle tone spasticity is common.
Areas covered: The prevalence, assessment, and pharmacological management of gait impairment and spasticity in MS and their effects on health-related quality of life (HRQoL) are discussed.
