Cannabidiol as a Potential Treatment for Anxiety Disorders. Blessing E.M.; Steenkamp M.M.; Manzanares J.; Marmar C.R. Neurotherapeutics, 2015, 12, 4, 825-36 doi:10.1007/s13311-015-0387-1 (ISSN: 1878-7479) Abstract : Cannabidiol (CBD), a Cannabis sativa constituent, is a pharmacologically broad-spectrum drug that in recent years has drawn increasing interest as a treatment for a range of neuropsychiatric disorders. The purpose of the current review is to determine CBD's potential as a treatment for anxiety-related disorders, by assessing evidence from preclinical, human experimental, clinical, and epidemiological studies. We found that existing preclinical evidence strongly supports CBD as a treatment for generalized anxiety disorder, panic disorder, social anxiety disorder, obsessive-compulsive disorder, [...]

It does not appear to alter consciousness or trigger a “high.” A recent surge in scientific publications has found preclinical and clinical evidence documenting value for CBD in some neuropsychiatric disorders, including epilepsy, anxiety, and schizophrenia. Evidence points toward a calming effect for CBD in the central nervous system. Interest in CBD as a treatment of a wide range of disorders has exploded, yet few clinical [...]

Paul Webster reports from Toronto. As Canada prepares to legalise recreational cannabis use next summer, the government faces increasingly tough questions about a widely praised national drug control experiment being closely watched internationally. “We’re approaching it purely from a public health and safety standpoint”, Prime Minister Justin Trudeau explained in a televised gathering in Toronto last autumn. “The questions around revenue and taxation are [...]

Preface Δ9-tetrahydrocannabinol (THC), the main psychoactive ingredient in cannabis, is a pressing concern to global mental health. Patterns of use are changing drastically due to legalisation, availability of synthetic analogues (‘spice’), cannavaping and aggrandizements in the purported therapeutic effects of cannabis. Many of THC’s reinforcing effects are mediated by the dopamine system. Due to complex cannabinoid-dopamine interactions there is conflicting evidence from human and animal research fields. Acute THC causes increased dopamine release and neuron [...]

It lacks the psychotomimetic and other psychotropic effects that the main plant compound D9 tetrahydrocannabinol (THC) being able, on the contrary, to antagonize these effects. This property, together with its safety profile, was an initial stimulus for the investigation of CBD pharmacological properties. It is now clear thatCBDhas therapeutic potential over a [...]

Journal of Palliative Medicine, 2019, May 13 https://doi.org/10.1089/jpm.2018.0528 Abstract : Background: Glioma is a devastating primary tumor of the central nervous system with difficult-to-manage symptoms. Cannabis products have been postulated to potentially benefit glioma patients. Recent state legalization allowed investigators an opportunity to study glioma patients' adoption of medical marijuana (MM). Objective: Our goals were to: (1) determine the prevalence of marijuana use, both through physician recommendation and self-medication, and (2) evaluate its perceived risks and [...]
