Abstract Cannabis sativa L., a member of the Cannabaceae family, has been thoroughly investigated for its diverse therapeutic properties, primarily attributed to cannabinoids such as delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). Secondary, metabolites like terpenes also exhibit pharmacological effects. This study examined the genotoxicity of a whole Cannabis sativa flower extract 160.32 mg/mL using three OECD-recommended protocols: the Ames test, micronucleus test, and comet assay. Five groups of six Wistar rats were used. Three doses of the extract (500, 1000, and 2000 mg/kgbw) or negative control (placebo) were administered orally, while cyclophosphamide monohydrate (20 mg/kgbw) was used as a positive control via intraperitoneal injection. Blood was collected for the comet test, and the animals were euthanized for bone marrow collection for the micronucleus...

Abstract Cannabis, derived from Cannabis sativa plants, is a prevalent illicit substance in the United States, containing over 400 chemicals, including 100 cannabinoids, each affecting the body’s organs differently upon ingestion. Cannabis hyperemesis syndrome (CHS) is a gut–brain axis disorder characterized by recurring nausea and vomiting intensified by excessive cannabis consumption. CHS often goes undiagnosed due to inconsistent criteria, subjective symptoms, and similarity to cyclical vomiting syndrome (CVS). Understanding the endocannabinoid system (ECS) and its dual response (pro-emetic at higher doses and anti-emetic at lower doses) is crucial in the pathophysiology of CHS. Recent research noted that type 1 cannabinoid receptors in the intestinal nerve plexus...

Abstract Objectives Cannabis-based products for medicinal use, also referred to as cannabinoid-containing products, particularly those containing cannabidiol as the primary active constituent, have shown to be a possible alternative in treating various health conditions in companion animals. Thus, this systematic review aims to synthesise and analyse the available data on the efficacy/effectiveness and safety of cannabis-based products for medicinal use in dogs and cats to assist in clinical decision-making. Materials and Methods A systematic review was conducted across PubMed, LILACS, Scopus, and Google Scholar from February 2014 to February 2024. The search strategy included both MeSH...

Abstract Background: Cannabis has been associated with psychopathology since ancient times, but controversies continue despite important advances in the field. This article is the fourth one in our decadal series of review articles that have been providing an update snapshot of the meandering journey of the research findings in this area. Aims: This narrative review of a comprehensive literature search over the past 10 years aims to provide an update and current understanding, while raising unanswered questions for the future, focusing on the following areas: (a) nosological changes in cannabis-related psychiatric syndromes; (b) psychopathology associated with the newer category of synthetic cannabinoids; (c) cannabis...

Accumulating evidence suggests potential adverse effects on fetal and neonatal outcomes following cannabis use in pregnancy. Objective  To update a living systematic review and meta-analysis to provide a timely understanding regarding cannabis use in pregnancy and fetal and neonatal outcomes. Data Sources  The previous review was updated by searching bibliographic databases MEDLINE, CINAHL, PsycInfo, Global Health, and Evidence-Based Medicine Reviews Cochrane Database of Systematic Reviews from November 1, 2021, through April 4, 2024. Study Selection  Cohort or case-control studies comparing pregnancies...

Abstract This paper introduces the special issue on cannabis use in Europe. It describes data on the prevalence of cannabis use in Europe and the more limited data on the prevalence of cannabis use disorders, one of the most common forms of drug problem treated in many countries in Europe. It summarises what research has indicated about the adverse effects of acute and chronic cannabis use and discusses potential health system responses that may reduce some of these harms. These include public education about the risks of cannabis use; screening and brief interventions in primary medical settings; and specialist treatment for cannabis use disorders....

ABSTRACT Introduction: The rising global prevalence and potential harms of cannabis use among adolescents and young adults are cause for concern. This systematic review focuses on the Arab world, compiling research on cannabis consumption among school and university students, where use has significantly increased but remains inadequately evaluated. Methods: The review was registered in PROSPERO (CRD42021285103). Following PRISMA 2020 guidelines, two researchers searched PubMed, Embase, Scopus, and PsycInfo from inception to 9 May 2024, with no filters or language restrictions. Grey literature was identified through structured searches in Google Scholar and ProQuest Dissertations & Theses Global on 30 August 2024, as well as through reference list...

Abstract Cannabis use for sleep is increasingly prevalent, yet its effects on sleep architecture remain unclear. This systematic review and meta-analysis examined polysomnographic evidence on cannabis’ impact on sleep parameters. Eighteen studies were identified, with nine suitable for meta-analysis. Findings indicate that cannabis administration does not consistently alter sleep duration, latency, wake time, efficiency, or sleep staging. While early studies suggested reductions in rapid eye movement sleep, these were primarily based on small-scale trials with high tetrahydrocannabinol doses and significant methodological limitations. More recent studies using larger samples and lower therapeutic doses of tetrahydrocannabinol have reported mixed (and often no) evidence of rapid eye...

Abstract Background Cannabis is increasingly recommended to treat female orgasmic disorder/difficulty (FOD/difficulty), a condition that affects up to 41% of women worldwide with no conventional medications. Aim To systematically review the existing literature on cannabis and its impact on female orgasm function. Methods A systematic review based on the PRISMA model evaluated the effects of cannabis on orgasm function in females with or without FOD/difficulty. Risk of bias was assessed for randomized and nonrandomized studies. Searches were conducted in PubMed, Google Scholar, Cochrane, and Embase. Outcomes Primary outcomes focused on the impact of cannabis on female orgasm function. Results Sixteen studies met inclusion criteria:...

Abstract Cannabis and its bioactive compounds, specifically tetrahydrocannabinol and cannabidiol, are rapidly growing in popularity for their therapeutic applications across a variety of medical specialties, including dentistry. This narrative review aims to explore the current and future applications of cannabinoids in dentistry and the therapeutic potential, problems, and ethical issues. Cannabinoids possess analgesic, anti-inflammatory, anxiolytic, and neuroprotective properties that may be beneficial in the treatment of orofacial neuropathic pain, temporomandibular joint disorders, myofascial pain dysfunction syndrome, bruxism, and obstructive sleep apnea. Despite their potential benefits, the integration of cannabinoids into dental practice is limited by the absence of standardized treatment regimens, insufficient high-quality clinical...
