Is cannabidiol an effective treatment for schizophrenia? R. Guinguis, M.I. Ruiz, G. Rada Medwave, 2017, 17, 7, e7010 DOI: 10.5867/medwave.2017.07.7010 Abstract Cannabidiol has recently been proposed as an antipsychotic for schizophrenia. However, its clinical use and safety is controversial. To answer this question, we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We identified six systematic reviews incorporating four primary studies overall, including two randomized trials. We extracted data from the systematic reviews, reanalyzed data from primary studies, conducted a meta-analysis and generated a summary of findings table [...]

Ayers JAMA Network Open, 2019, 2, (10), e1913853. doi: 10.1001/jamanetworkopen.2019.13853 Introduction Cannabidiol (CBD) is widely promoted as a panacea. For example, the cannabis brand MedMen claims CBD treats acne, anxiety, opioid addiction, pain, and menstrual problems.1 However, the US Food and Drug Administration has only approved highly purified CBD (Epidiolex) for treating epilepsy. To our knowledge, there is currently no population-focused surveillance of public interest in CBD. Consequently, many question whether CBD should be prioritized by public health leaders [...]

Methods : We summarize the findings of English-language epidemiological studies reporting current (past-year) comorbidity and of controlled clinical trials of treatment in which the majority of participants had diagnosed CUD and a specific comorbid disorder. Results : There is substantial CUD comorbidity among community-dwelling adults with major psychiatric disorders: 4–6% for depression, 14% for bipolar disorder, 5% for anxiety disorder, and 16% for schizophrenia. Conversely, there is substantial psychiatric [...]

Adi Jaffe, Psychology Today Posted Dec 10, 2018 https://www.psychologytoday.com/us/blog/all-about-addiction/201812/ayahuasca-addiction-thats-trip Doctors have been prescribing drugs to treat substance addictions for decades. Most commonly known is the use of buprenorphine and naloxone (Suboxone) in opioid addiction which provides some opioid activation, helping with withdrawal and cravings, without the same “high” and many of the associated psychosocial effects of illicit drug use. But Suboxone isn’t the only one – methadone, modafinil, naltrexone, ketamine, and many more examples exist in which the use of a chemical has been prescribed to help [...]

Introduction 1.1 Cannabinoid Function Endocannabinoids are bioactive lipids that have a range of interesting activities mediated by two G-protein-coupled receptors (CB1 and CB2) and other putative targets [1-3]. The CB1 receptor is present in the central nervous system and mediates the psychotropic effects of exogenous cannabinoids such as Δ9-tetrahydrocannabinol (THC), the active component of marijuana. In the brain, endocannabinoids and cannabinoids combine with CB1 cannabinoid receptors on axon terminals and regulate ion channel activity and neurotransmitter release [4]. Binding to the CB1 receptor is responsible for [...]

Mauck Mayo Clinic Proceedings, 2019, 94, (9), 1840-1851 https://doi.org/10.1016/j.mayocp.2019.01.003 Abstract Cannabidiol (CBD) oils are low tetrahydrocannabinol products derived from Cannabis sativa that have become very popular over the past few years. Patients report relief for a variety of conditions, particularly pain, without the intoxicating adverse effects of medical marijuana. In June 2018, the first CBD-based drug, Epidiolex, was approved by the US Food and Drug Administration for treatment of rare, severe epilepsy, further putting the spotlight on CBD and hemp oils. There is a growing body of preclinical and [...]

Busch JAMA Published online August 2, 2019 doi:10.1001/jama.2019.10728 Major depressive disorder (MDD) affects approximately 17.3 million adults in the United States,1 with a 12-month and lifetime prevalence of 10.4% and 20.6%, respectively.2 Conducting clinical trials and developing new treatments for depression can be difficult because of spontaneous recovery rates and placebo effects.3 In addition, many patients with chronic and refractory MDD do not experience clinical improvement even after several treatment courses. There is growing interest in the use of exercise and improved nutrition to treat depression,4 [...]
