The Chemistry of Cannabis and Cannabinoids

Abstract The science of cannabis and cannabinoids encompasses a wide variety of scientific disciplines and can appear daunting to newcomers to the field. The encroachment of folklore and ‘cannabis culture’ into scientific discussions can cloud the situation further. This Primer Review is designed to give a succinct overview of the chemistry of cannabis and cannabinoids. It is hoped that it will provide a useful resource for chemistry undergraduates, postgraduates and their instructors, and experienced chemists who require a comprehensive and up to date summary of the field. The Review begins with a brief overview of the history and botany of cannabis, then goes on...

A Proteomic View of Cellular and Molecular Effects of Cannabis

Abstract: Cannabis (Cannabis sativa), popularly known as marijuana, is the most commonly used psychoactive substance and is considered illicit in most countries worldwide. However, a growing body of research has provided evidence of the therapeutic properties of chemical components of cannabis known as cannabinoids against several diseases including Alzheimer’s disease (AD), multiple sclerosis (MS), Parkinson’s disease, schizophrenia and glaucoma; these have prompted changes in medicinal cannabis legislation. The relaxation of legal restrictions and increased socio-cultural acceptance has led to its increase in both medicinal and recreational usage. Several biochemically active components of cannabis have a range of effects on the biological system. There is...

UHPLC-MS/MS analysis of cannabidiol metabolites in serum and urine samples. Application to an individual treated with medical cannabis

Please use this link to access this publication. Abstract No analytical assay is currently available for the simultaneous determination of CBD major metabolites in serum or urine samples of individuals treated with medical cannabis or CBD-based pharmaceuticals. We developed and validated a method using ultra-high-performance liquid chromatography coupled with tandem mass spectrometry (UHPLC–MS/MS) for quantifying cannabidiol (CBD) and its metabolites, cannabidiol-7-oic acid (7-COOH-CBD), 7- hydroxycannabidiol (7-OH-CBD), 6-alpha-hydroxycannabidiol (6-α–OH–CBD) and 6-beta-hydroxycannabidiol (6-β–OH–CBD) in serum and urine samples of an individual treated with medical cannabis. The ionization was performed by electrospray in negative mode to reach the sensitivity required to detect trace amounts, with limits of quantification ranging from 0.05 to 0.1 ng/mL. The...

Cannabidiol Isolated From Cannabis sativa L. Protects Intestinal Barrier From In Vitro Inflammation and Oxidative Stress

Abstract The relevance and incidence of intestinal bowel diseases (IBD) have been increasing over the last 50 years and the current therapies are characterized by severe side effects, making essential the development of new strategies that combine efficacy and safety in the management of human IBD. Herbal products are highly considered in research aimed at discovering new approaches for IBD therapy and, among others, Cannabis sativa L. has been traditionally used for centuries as an analgesic and anti-inflammatory remedy also in different gastrointestinal disorders. This study aims to investigate the effects of different C. sativa isolated compounds in an in vitro model of intestinal epithelium. The ability of treatments to modulate...

Cannabidiol (CBD) and other drug use among young adults who use cannabis in Los Angeles

Please use this link to access this publication. Abstract Introduction Cannabidiol (CBD) is purportedly a promising therapeutic agent to provide relief for a variety of medical conditions with mild or no psychoactive effects. However, little is known about young adults who use cannabis and CBD-dominant products, and associations between CBD use and other drug use. Methods Young adults (aged 24–32) who currently used cannabis (n = 239) were surveyed in Los Angeles in March 2019 through March 2020. The sample was divided into CBD-dominant (at least 1:1 CBD:THC ratio) and THC-dominant product users. We described CBD forms, reasons and conditions for CBD use and...

The endocannabinoid system, cannabis, and cannabidiol: Implications in urology and men’s health

Abstract Background: The endocannabinoid system is a neuromodulatory system responsible for partial regulation of cognitive and emotional processes in the human central nervous system such as behavior, mood disorders, and neurologic disorders such as epilepsy. The endocannabinoid system is also prevalent throughout the peripheral nervous system and human body and its receptors and signaling pathways are present and active in areas including the male and female reproductive tracts and organ systems such as the urologic and gastrointestinal system. Summary: The purpose of this article is to provide the reader with a brief background on the endocannabinoid system and to discuss the implications of the...

Cannabis sativa L. as a Natural Drug Meeting the Criteria of a Multitarget Approach to Treatment

Abstract: Cannabis sativa L. turned out to be a valuable source of chemical compounds of various structures, showing pharmacological activity. The most important groups of compounds include phytocannabinoids and terpenes. The pharmacological activity of Cannabis (in epilepsy, sclerosis multiplex (SM), vomiting and nausea, pain, appetite loss, inflammatory bowel diseases (IBDs), Parkinson’s disease, Tourette’s syndrome, schizophrenia, glaucoma, and coronavirus disease 2019 (COVID-19)), which has been proven so far, results from the affinity of these compounds predominantly for the receptors of the endocannabinoid system (the cannabinoid receptor type 1 (CB1), type two (CB2), and the G protein-coupled receptor 55 (GPR55)) but, also, for peroxisome proliferator activated...

Changes in delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) concentrations in cannabis over time: systematic review and meta-analysis

Abstract Background and aims Cannabis products with high delta-9-tetrahydrocannabinol (THC) concentrations carry an increased risk of addiction and mental health disorders, while it has been suggested that cannabidiol (CBD) may moderate the effects of THC. This study aimed to systematically review and meta-analyse changes in THC and CBD concentrations in cannabis over time (PROSPERO registration: CRD42019130055). Design Embase, MEDLINE® and Epub Ahead of Print, In-Process and Other Non-Indexed Citations and Daily, Global Health, PsycINFO and Scopus were searched from inception to 27/03/2019 for observational studies reporting changes in mean THC and/or CBD concentration in cannabis over at least three annual time points. Searches and...

Medicinal applications of cannabis/cannabinoids

Please use this link to access this publication. ABSTRACT Regulatory approvals for Epidiolex (purified cannabidiol) in the treatment of childhood drug resistant epilepsy have set a precedent for the use of cannabinoids as a prescribed medicine. Two common reasons cited for the use and prescription of cannabis-based products are pain and insomnia. Unlike drug resistant epilepsy, the level of evidence of efficacy in pain is poorly developed. The lowest quality trials with the greatest methodological shortcomings suggest some benefit, a level of evidence that is inconsistent with widespread prescribing. The evidence in insomnia is scant. Ongoing trial development and critical review of the literature should not be overshadowed by increasing permissiveness...

Cannabis constituents interact at the drug efflux pump BCRP to markedly increase plasma cannabidiolic acid concentrations

Abstract Cannabis is a complex mixture of hundreds of bioactive molecules. This provides the potential for pharmacological interactions between cannabis constituents, a phenomenon referred to as “the entourage effect” by the medicinal cannabis community. We hypothesize that pharmacokinetic interactions between cannabis constituents could substantially alter systemic cannabinoid concentrations. To address this hypothesis we compared pharmacokinetic parameters of cannabinoids administered orally in a cannabis extract to those administered as individual cannabinoids at equivalent doses in mice. Astonishingly, plasma cannabidiolic acid (CBDA) concentrations were 14-times higher following administration in the cannabis extract than when administered as a single molecule. In vitro transwell assays identified CBDA as...
