Cannabis for Sleep: Short-Term Benefit, Long-Term Disruption ? Michael Vlessides Medscape, January 24, 2020 https://www.medscape.com/viewarticle/924202_print Patients suffering from chronic pain who take medicinal cannabis to initiate and maintain sleep appear to experience short-term benefit, but long-term use may ultimately disrupt slumber, new research shows. Investigators found whole-plant medical cannabis use was associated with fewer problems with respect to waking up at night, but they also found that frequent medical cannabis use was associated with more problems initiating and maintaining sleep. "Cannabis may improve overall sleep in the short term," study investigator Sharon Sznitman, PhD, University of Haifa Faculty of Social Welfare and Health Sciences in Israel, [...]

ISERSON Cambridge Quarterly of Healthcare Ethics, 2019, 28, 168–177. © Cambridge University Press 2018. doi : 10.1017/S0963180118000518 Abstract : The available treatments for disorders affecting large segments of the population are often costly, complex, and only marginally effective, and many have numerous side effects. These disorders include dementias, debilitating neurological disorders, the multiple types of drug addiction, and the spectrum of mental health disorders. Preliminary studies have shown that a variety of psychedelic and similar U.S. Drug Enforcement Administration Schedule I drugs may offer better treatment options than those that currently exist and pose potentially [...]

Khajah and Willias Masocha Molecules, 2020, 25, 106; doi:10.3390/molecules25010106 Abstract : Neuropathic pain associated with nucleoside reverse transcriptase inhibitors (NRTIs), therapeutic agents for human immunodeficiency virus (HIV), responds poorly to available drugs. Smoked cannabis was reported to relieve HIV-associated neuropathic pain in clinical trials. Some constituents of cannabis (Cannabis sativa) activate cannabinoid type 1 (CB1) and cannabinoid type 2 (CB2) receptors. However, activation of the CB1 receptor is associated with side eects such as psychosis and physical dependence. Therefore, we investigated the effect of B-caryophyllene (BCP), [...]

Ott, Melanie Müller, Barbara Silcher, Marius E. Sichler, Maximilian J. Löw, Jannek M. Wagner and Yvonne Bouter Frontiers in Behavioral Neuroscience, 2019, Volume 13, Article 94 doi : 10.3389/fnbeh.2019.00094 The Cannabis plant contains more than 100 currently known phytocannabinoids. Regarding the rising consumption of the non-psychotropic phytocannabinoid cannabidiol (CBD) in people’s everyday life (e.g., beauty products, food and beverages), the importance of studies on the influence of CBD on healthy humans and rodents is evident. Therefore, the behavioral profile of CBD was investigated with [...]

Arnold and Tim Karl International Journal of Neuropsychopharmacology, 2010, 13, 861–876. doi : 10.1017/S1461145709990605 Abstract Cannabis contains over 70 unique compounds and its abuse is linked to an increased risk of developing schizophrenia. The behavioural profiles of the psychotropic cannabis constituent D9 tetrahydro-cannabinol (D9-THC) and the non-psychotomimetic constituent cannabidiol (CBD) were investigated with a battery of behavioural tests relevant to anxiety and positive, negative and cognitive symptoms of schizophrenia. Male adult C57BL/6JArc mice were given 21 daily intraperitoneal injections of vehicle, [...]

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 [...]
