The nephrologist’s guide to cannabis and cannabinoids, Joshua L. Rein, 2020

The nephrologist’s guide to cannabis and cannabinoids Joshua L. Rein   Purpose of review Cannabis (marijuana, weed, pot, ganja, Mary Jane) is the most commonly used federally illicit drug in the United States. The present review provides an overview of cannabis and cannabinoids with relevance to the practice of nephrology so that clinicians can best take care of patients. Recent findings Cannabis may have medicinal benefits for treating symptoms of advanced chronic kidney disease (CKD) and end-stage renal disease including as a pain adjuvant potentially reducing the need for opioids. Cannabis does not seem to affect kidney function in healthy individuals. However, renal function should be [...]

Do medical cannabis growers attempt to produce cannabis with different cannabinoid concentrations than recreational growers?, Sharon R. Sznitman et al., 2019,

Do medical cannabis growers attempt to produce cannabis with different cannabinoid concentrations than recreational growers? Sharon R. Sznitman, Monica J. Barratt, Tom Decorte, Pekka Hakkarainen, Simon Lenton, Gary Potter, Bernd Werse and Chris Wilkins Drugs and Alcohol Today, 2019, 19, (4), 251-256, Doi : 10.1108/DAT-06-2019-0021   Abstract Purpose – It is conceivable that cannabis cultivators who grow for medical purposes aim to improve the therapeutic index of their cannabis by attempting to produce particular concentrations of CBD and/or THC. The purpose of this paper is to examine whether small-scalemedical cannabis growers differ fromthose growing for recreational reasons in terms of self-assessed concentrations of THC and CBD [...]

Totality of the Evidence Suggests Prenatal Cannabis Exposure Does Not Lead to Cognitive Impairments : A Systematic and Critical Review, Ciara A. Torres et al., 2020

Totality of the Evidence Suggests Prenatal Cannabis Exposure Does Not Lead to Cognitive Impairments : A Systematic and Critical Review Ciara A. Torres, Christopher Medina-Kirchner, Kate Y. O'Malley and Carl L. Hardt Frontiers in Psychology, 2020, Vol 11, Art 816, 1-28. Doi : 10.3389/fpsyg.2020.00816   Background: Despite limited data demonstrating pronounced negative effects of prenatal cannabis exposure, popular opinion and public policies still reflect the belief that cannabis is fetotoxic. Methods: This article provides a critical review of results from longitudinal studies examining the impact of prenatal cannabis exposure on multiple domains of cognitive functioning in individuals aged 0 to 22 years. A literature search was [...]

Developing Robust Standardised Analytical Procedures for Cannabinoid Quantification : Laying the Foundations for an Emerging Cannabis-Based Pharmaceutical Industry, Matthew T. Welling et al., 2019

Developing Robust Standardised Analytical Procedures for Cannabinoid Quantification : Laying the Foundations for an Emerging Cannabis-Based Pharmaceutical Industry Matthew T. Welling, Lei Liu, Arno Hazekamp, Ashley Dowell, Graham J. King Medical Cannabis & Cannabinoids, 2019, 2, 1–13 Doi : 10.1159/000496868   Abstract The plant genus Cannabis is a prolific producer of unique pharmaceutically relevant metabolites, commonly referred to as cannabinoids. Robust and standardised methods for the quantification of cannabinoids within botanical and drug forms is a critical step forward for an emerging Cannabis- based pharmaceutical industry, which is poised for rapid expansion. Despite a growing body of analytical methods for the quantification of cannabinoids, few have [...]

Cannabinoids in Gynecological Diseases, Petra Luschnig et al., 2019

Cannabinoids in Gynecological Diseases Petra Luschnig, Rudolf Schicho Medical Cannabis & Cannabinoids, 2019, 2, 14-21 Doi : 10.1159/000499164   Abstract The endocannabinoid system (ECS) is a multifunctional homeostatic system involved in many physiological and pathological conditions. The ligands of the ECS are the endocannabinoids, whose actions are mimicked by exogenous cannabinoids, such as phytocannabinoids and synthetic cannabinoids. Responses to the ligands of the ECS are mediated by numerous receptors like the classical cannabinoid receptors (CB1 and CB2) as well as ECS-related receptors, e.g., G protein-coupled receptors 18 and 55 (GPR18 and GPR55), transient receptor potential ion channels, and nuclear peroxisome proliferator-activated receptors. The ECS regulatesalmost all levels of [...]

The Intricate Influence of the Placebo Effect on Medical Cannabis and Cannabinoids, Jürg Gertsch, 2018

The Intricate Influence of the Placebo Effect on Medical Cannabis and Cannabinoids Jürg Gertsch Medical Cannabis Cannabinoids,  2018, 1, 60–64 Doi : 10.1159/000489291 Abstract The botanical drug cannabis flos (inflorescence of Cannabis sativa L.) has a unique popular status as being a potent recreational drug and bona fide universal remedy (panacea). Generally, cannabinoids exert therapeutic effects in a broad range of pathophysiologies related to inflammation, pain, metabolic and stress-related conditions in preclinical animal models. However, the translation of such data to humans still lacks an evidence-based foundation. Motivated by the booming cannabis manufacturing industry and the increasing worldwide self-therapy by patients, there are cumulative accounts [...]
