Abstract Purpose of review Anxiety is a prevalent mental health condition which manifests as a disproportionate response of fear to a perceived threat. Different types of anxiety disorders vary in their pathophysiology, symptoms and treatments. The causes of anxiety disorders are complex and largely unknown; however, it has been suggested that a number of brain mechanisms and neurotransmitters are involved in the development of these conditions. While there are non-pharmacological treatments for anxiety, many patients are prescribed medications such as selective serotonin reuptake inhibitors, serotonin and noradrenaline reuptake inhibitors and/or benzodiazepines. Unfortunately, these medications have issues with efficacy and safety, and therefore, there is...

Please use this link to access publication OBJECTIVE: The endocannabinoid system is involved in pain perception and inflammation. Cannabis contains delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), which are cannabinoids that bind to endocannabinoid system receptors. A fatty acid amide called palmitoylethanolamide (PEA) enhances endogenous cannabinoids. Given that use of medical cannabis is increasing, we sought to characterize patterns of cannabis use for gynecologic pain and its effectiveness as an analgesic. DATA SOURCES: We searched PubMed, EMBASE, Scopus, Cochrane, and ClinicalTrials.gov using terms for “woman,” “cannabis,” and “pain” or “pelvic pain” or “endometriosis” or “bladder pain” or “cancer.” The search was restricted to English-language articles published between January...

Please use this link to access publication Abstract Introduction:Cannabis sativa L. (C. sativa) is used since ancient times to produce fabrics, baskets, and cords. Later, different ethnic groups used to burn the leaves and flowers of psychotropic cultivars with high Δ9-tetrahydrocannabinol (D9-THC) levels, during the religious or propitiatory rites to alter the state of consciousness. To date, it is not known whether also nonpsychotropic cultivars of C. sativa were used during these rites, and whether these varieties could have an effect on human behavior. This study aimed to evaluate the behavioral effects of an extract of nonpsychotropic C. sativa (NP-CS) in mice. Materials and Methods: An extract of a nonpsychotropic...

Abstract The combination of the ongoing opioid crisis, inappropriateness of long-term use of NSAIDs, limited efficacy and tolerability of existing analgesics and the fact that no new analgesics (except for anti-migraine medications) were launched during the past two decades, has considerably depleted the arsenal of chronic pain pharmacotherapy. No wonder therefore, that the old-new player, medicinal cannabis (MC), has erupted onto the pain field. Indeed, MC, which consists of herbal cannabis (HC), in either inflorescence or oil extract forms, and cannabis-based medicinal products (CBMP), is being increasingly used in chronic pain management. As a result of public pressure by media, patient advocacies and political...

Please use this link to access publication Abstract Purpose This systematic review assesses currently available clinical information on which cannabinoids and what range of doses have been used to achieve positive effects in a diversity of medical context. Methods The data were collected according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol guidelines. Inclusion criteria were articles that assessed administration of any cannabinoid to any clinical population, reported in the ClinicalTrials.gov or PubMed databases, that involved a comparison with other treatment or placebo and a result measurement to assess the effectiveness or ineffectiveness of the cannabinoid. Exclusion criteria were review or letter; articles not in the English...

Please use this link to access publication Abstract Cannabis has been used for centuries for its medicinal properties. Given the dangerous and unpleasant side effects of existing analgesics, the chemical constituents of Cannabis have garnered significant interest for their antinociceptive, anti-inflammatory and neuroprotective effects. To date, Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) remain the two most widely studied constituents of Cannabis in animals. These studies have led to formulations of THC and CBD for human use; however, chronic pain patients also use different strains of Cannabis (sativa, indica and ruderalis) to alleviate their pain. These strains contain major cannabinoids, such as THC and CBD, but they also contain a wide variety of cannabinoid and noncannabinoid...

Abstract Rationale There has been increasing attention on cannabis use for medical purposes, but there is currently a lack of data on its epidemiology. Objectives To examine the epidemiology of self-reported cannabis use for medical purposes by (1) estimating its prevalence, (2) comparing gender and age differences, and (3) investigating what reasons they were used to manage. Methods Participants included 27,169 respondents (aged 16–65) who completed Wave 1 of The International Cannabis Policy Study (ICPS) conducted across Canada and the USA in 2018 via online surveys. Cannabis policy conditions were “US legal–recreational” (legal for both recreational and medical uses), “US legal–medical only”, “US illegal”,...

Please use this link to access publication Abstract There have been conflicting reports on the impact of Cannabis sativa impact on reproductive function. Hence this study was aimed to ascertain the impact of tetrahydrocannabinol (THC) and cannabidiol (CBD) binding affinity on human androgen receptor (AR) via computational molecular dynamic simulation. The human AR coordinate in this study is derived from human AR in complex with the ligand metribolone (R18) (PBD ID: 1E3G) template using (MODELER version. 9.15). CBD (PubChem CID: 644019), and THC (PubChem CID: 16078) 2D structures were retrieved from PubChem and docked (Autodock-Vina inbuilt in PyMol into the active site of human AR using...

Abstract Evidence on the use and efficacy of medical cannabis for children is limited. We examined clinical and epidemiological characteristics of medical cannabis treatment and caregiver-reported effects in children and adolescents in Switzerland. We collected clinical data from children and adolescents (< 18 years) who received Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), or a combination of the two between 2008 and 2019 in Switzerland. Out of 205 contacted families, 90 agreed to participate. The median age at the first prescription was 11.5 years (interquartile range (IQR) 6–16), and 32 patients were female (36%). Fifty-one (57%) patients received CBD only and 39 (43%) THC. Patients were more likely to receive...
