Cannabidiol inhibits THC-elicited paranoid symptoms and hippocampal-dependent memory impairment Englund A, Morrison PD, Nottage J, Hague D, Kane F, Bonaccorso S, Stone JM, Reichenberg A, Brenneisen R, Holt D, Feilding A, Walker L, Murray RM, Kapur S. Beckley Foundation, 2017. https://beckleyfoundation.org/resource/cannabidiol-inhibits-thc-elicited-paranoid-symptoms-and-hippocampal-dependent-memory-impairment/ Abstract Community-based studies suggest that cannabis products that are high in delta9-tetrahydrocannabinol (THC) but low in cannabidiol (CBD) are particularly hazardous for mental health. Laboratory-based studies are ideal for clarifying this issue because THC and CBD can be administered in pure form, under controlled conditions. In a between-subjects design, we tested the hypothesis that pre-treatment with CBD inhibited THC-elicited psychosis and cognitive impairment. Healthy participants were [...]

The Permanente Journal, 2019, 23 Abstract CONTEXT: Cannabidiol (CBD) is one of many cannabinoid compounds found in cannabis. 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 studies of [...]

C : Springer Nature Switzerland AG Abstract : At present, clinical interest in the plant-derived cannabinoid compound cannabidiol (CBD) is rising exponentially, since it displays multiple therapeutic properties. In addition, CBD can counteract the undesirable effects of the psychoactive cannabinoid Δ9-tetrahydrocannabinol (Δ9-THC) that hinder clinical development of cannabis-based therapies. Despite this attention, the mechanisms of CBD action and its interaction with Δ9-THC are still not completely elucidated. Here, by combining in vivo [...]
Lire la suiteClinical Manifestations of Cannabis Use Disorder Alan J. Budney, Jacob T. Borodovsky, and Ashley A. Knapp C Springer Nature Switzerland AG 2019 Introduction : Cannabis use disorder (CUD) or its colloquial synonym, cannabis addiction, remains controversial in that many in the general public believe that cannabis use does not pose substantial risk for harm and is not addictive in the same sense that tobacco, alcohol, cocaine, or heroin is addictive. Although assessment of people’s beliefs about addiction and harm is complicated by the lack of a consensus definition or a common understanding of addiction, the difference in perception of risk between cannabis and other [...]

Damian McNamara, CME, Laurie Barclay, MD Posted: 12/14/2018 Clinical Context The effects of cannabis in humans include euphoria, increased sensitivity to external experience, relaxation, and potential for addiction. Cannabidiol is a compound in the cannabis plant that lacks euphoric and addictive qualities and that may be useful to treat conditions including chronic pain, nausea, epilepsy, psychosis, and anxiety. The optimal therapeutic dose of CBD has not yet been determined, and it has been used in a wide dose range from 2.85 to 50 mg/kg/day. The therapeutic effects of CBD appear to emanate from its interaction [...]
