Abstract The purpose of this study was to evaluate the antioxidant and antimicrobial properties of two extracts from a new Chinese accession (G-309) of Cannabis sativa L. (Δ9-tetrahydrocannabinol <0.2%) with high content of propyl side chain phytocannabinoids. Dried flowering tops, as such and after hydrodistillation of the essential oil, were extracted with acidic hexane to produce the Cannabis Chinese hexane extract 1 (CChHE1) and 2 (CChHE2), respectively. The phytochemical profile of CChHE1 and CChHE2 was investigated by gas chromatography–mass spectrometry (GC–MS) and liquid chromatography–diode array detector–electrospray ionization–tandem mass spectrometry (LC-DAD-ESI-MS/MS) analyses. The antioxidant properties were assessed by several...

ABSTRACT Background: Inflammatory bowel diseases (IBDs) are chronic, idiopathic, inflammatory, gastrointestinal disorders. The endocannabinoid system may have a role in the pathogenesis of IBD. We aimed to assess whether cannabis treatment influences endocannabinoids (eCBs) level and clinical symptoms of IBD patients. Methods: Blood samples and biopsies were taken from IBD patients treated by either cannabis or placebo for 8 weeks. Immunohistochemistry for N-acyl-phosphatidylethanolamine-selective phospholipase D (NAPE-PLD) and fatty acid amide hydrolase (FAAH) expression was done on colon biopsies, and sample levels of anandamide (AEA), eCB2-arachidonylglycerol (2-AG), arachidonic acid (AA), palmitoylethanolamine (PEA), and oleoylethanolamine (OEA) were measured in patient’s sera before and after cannabis treatment. Caco-2 cells were...

ABSTRACT Ethnopharmacological relevance Cannabis sativa L. is an aromatic annual herb belonging to the family Cannabaceae and it is widely distributed worldwide. Cultivation, selling, and consumption of cannabis and cannabis related products, regardless of its use, was prohibited in Lebanon until April 22, 2020. Nevertheless, cannabis oil has been traditionally used unlawfully for many years in Lebanon to treat diseases such as arthritis, diabetes, cancer and few neurological disorders. Aim of the study The present study aims to evaluate the phytochemical and anti-inflammatory properties of a cannabis oil preparation that is analogous to the illegally used cannabis oil in Lebanon. Materials and...

They often report sociality, coping with unpleasant affect and having positive experiences as important reasons for cannabis use, suggesting that cannabis improves their quality of life (QoL) and psychosocial functioning. However, based on previous studies we hypothesize that cannabis use is negatively associated with long-term subjective QoL and psychosocial functioning in people with a psychotic disorder. Methods We included 2994 people with a psychotic disorder (36.4% female), mean age 44.4 (SD 11.9), mean illness duration 17.2 years (SD 11.1), who participated in two yearly routine outcome assessments between...

ABSTRACT Background: Research suggests emotion dysregulation is a transdiagnostic risk factor for substance use and addiction and that stress may lead to problematic cannabis use. Thus, the current study examines how emotion dysregulation moderates the associations between stress (stressful life events and perceived stress) and problematic cannabis use. Methods: Eight hundred and fifty-two adults reporting any lifetime cannabis use completed an anonymous online survey. Participants completed a brief demographic questionnaire and were asked to report their past 30-day use of cannabis, alcohol, nicotine, and illicit substances. Problematic cannabis use (via the Marijuana Problem Scale), emotion dysregulation (via the Difficulties in Emotion Regulation Scale), perceived stress (via the Perceived Stress...

Abstract For centuries, cannabis and its components have been used to manage a wide variety of symptoms associated with many illnesses. Gastrointestinal (GI) diseases are no exception in this regard. Individuals suffering from inflammatory bowel disease (IBD) are among those who have sought out the ameliorating properties of this plant. As legal limitations of its use have eased, interest has grown from both patients and their providers regarding the potential of cannabis to be used in the clinical setting. Similarly, a growing number of animal and human studies have been undertaken to evaluate the impact of cannabis and cannabinoid signaling elements on the natural...

The current study examined changes in cannabis use and modes of consumption among 16- to 19-year-olds in three markets with different regulatory frameworks: England, Canada, and the United States (US). Methods: Repeat cross-sectional online surveys were conducted in 2017, 2018, and 2019, with samples of 16- to 19-year-olds recruited from commercial panels in Canada (n = 11,779), England (n = 11,117), and the US (n = 11,869). Regression models examined changes in the prevalence of any cannabis use and use of...

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...

Abstract Background: Eleven states and the District of Columbia have implemented laws allowing for the use of cannabis, which is prompting studies of the patterns, determinants, and health outcomes of its use, primarily among young adults (1). Cannabis use is less prevalent among older adults (2–4), and studies of its use in this population are scarce. We believe more investigations are warranted. One reason is that some older adults use cannabis for the management of pain; disorders of mood, anxiety, and sleep; and other medical conditions (5). Another reason is that older adults are susceptible to adverse...

Abstract More than half of U.S. states legalized medical or recreational sale and possession of cannabis since the prevalence of cannabis use was last estimated among U.S. military veterans in 2014. To provide updated estimates of the prevalence and correlates of cannabis use, cannabis use disorder (CUD), and medical cannabis card possession in this population, data were analyzed from the 2019–2020 National Health and Resilience in Veterans Study, a nationally representative survey of 4,069 veterans ages 22–99 years who reported on their past-6-month cannabis use, CUD symptoms, and possession of a medical cannabis card. An estimated 11.9% [95% confidence interval...
