The bioactive components of Cannabis sativa L. can be classified into two main groups: cannabinoids and terpenes. These bioactive components of Cannabis sativa L. leaf and inflorescence extracts were analyzed. Mice were systemically administered 30 mg/kg of Cannabis sativa L. leaf extract 1 h before lipopolysaccharide (LPS) administration, and behavioral tests were performed. We conducted an investigation into the oxygen saturation, oxygen tension, and degranulation of mast cells (MCs) in the deep cervical lymph nodes (DCLNs). To evaluate the anti-inflammatory effect...

Abstract Study objectives Rates of cannabis use disorder (CUD) appear to be increasing nationally, with increases greater in states that legalized cannabis use. However, as legalization has progressed and stigma declined, some of these apparent increases could be due to greater willingness of survey respondents and patients to acknowledge cannabis involvement. Biological indicators of cannabis use overcome some concerns about trends denoted by self-report data whose validity is potentially changing over time. Our objective was to investigate the relationship between medical cannabis laws (MCL) and recreational cannabis laws (RCL) and the prevalence of cannabis-positive urine...

Abstract Background: Studies on medicinal cannabis (MC) have primarily investigated effects on diseases and symptoms, while there is only sparse knowledge on patients' health-related quality of life. Our aim was, firstly, to compare the health-related quality of life of patients (MC users and non-users) within four specified diagnostic indications (multiple sclerosis, paraplegia, neuropathy, and nausea and vomiting after chemotherapy) with that of patients with other diagnostic indications (MC users only) and the adult population (non-users only). Secondly, we estimate the associations between use of MC and health-related quality of life for patients in the four specified diagnostic indications. Methods: We collected data on quality-adjusted life years...

Abstract Background Cannabis is the third most widely used psychoactive substance globally, and its consumption has been increasing, particularly with the growing trend of legalization for medicinal and recreational use. Recent studies have raised concerns about the potential impact of cannabis on respiratory health, specifically the risk of asthma, a significant public health concern. This systematic review aimed to consolidate research on the association between cannabis use and the risk of asthma. Methods A comprehensive search was conducted across PubMed, Embase, and Web of Science, covering studies published up to September 30, 2024. We included peer-reviewed observational studies evaluating the link between cannabis consumption...

IASP has identified that a key missing evidence in this debate is data from observational cohort studies, analyzed with comparative effectiveness methods. In a medically supervised context to the use of marijuana for chronic pain, we identified 440 patients certified for medical marijuana by pain specialists in a single healthcare system. They were characterized by a battery of patient-reported outcomes stored electronically in the University of Pittsburgh Patient Outcomes Repository for Treatment (PORT). At 3 months, 38.6% were responders, based on...

Summary Cannabis in the USA is transitioning from a nationwide illegal status to liberalisation for medicinal or recreational use across different jurisdictions. As the acceptability and accessibility of cannabis continue to grow, updated knowledge on the cancer risk from recreational cannabis use is necessary to inform recommendations by public health organisations, policy makers, and clinical practitioners. We reviewed the evidence to date. Our umbrella review of current global epidemiological evidence reveals that links between cannabis exposure and cancer risk are more suggestive than conclusive. The cancer type most closely linked to cannabis use is non-seminoma testicular cancer. However, evidence is emerging of an increased...

However, data on substance use in these patients are lacking. This study aims to evaluate the prevalence of drug dependence in palliative care patients with advanced cancer and correlate with symptom distress and opioid use. Methods Palliative care patients with advanced cancer interested in participation in a medicinal cannabis trial were required to complete Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), Edmonton Symptom Assessment Scale (ESAS) and record of concomitant medications including baseline opioid use as part of...

Abstract Introduction: As the medically prescribed use of cannabis flower continues to increase, there is a need to understand how vaporized cannabis can acutely affect driving-related skills and risk-taking behaviors in medicinal populations. Method: Given this, the present study examined the acute effects of vaporized cannabis flower on measures of hazard perception, driving-related risk-taking behaviors, and subjective perceptions of driving skills in a sample of adult medicinal cannabis patients. Participants (N = 38, M age = 43) attended both a baseline (no cannabis) and intervention appointment (with cannabis consumption), where they completed video-based tasks and self-report measures of driving ability. Results: After vaporizing one dose of their prescribed cannabis flower, participants exhibited no...

Abstract For millennia, various cultures have utilized cannabis for food, textile fiber, ethno-medicines, and pharmacotherapy, owing to its medicinal potential and psychotropic effects. An in-depth exploration of its historical, chemical, and therapeutic dimensions provides context for its contemporary understanding. The criminalization of cannabis in many countries was influenced by the presence of psychoactive cannabinoids; however, scientific advances and growing public awareness have renewed interest in cannabis-related products, especially for medical use. Described as a 'treasure trove,' cannabis produces a diverse array of cannabinoids and non-cannabinoid compounds. Recent research focuses on cannabinoids for treating conditions such as anxiety, depression, chronic pain, Alzheimer's, Parkinson's, and epilepsy. Additionally, secondary metabolites like phenolic compounds, terpenes, and terpenoids are...

Abstract Objective To document the prevalence and correlates of suicidal ideation (SI) among individuals seeking cannabis-based medicinal products (CBMPs); to test whether SI declines or intensifies after three months of CBMP treatment and to document 12-month trajectories of depression in those reporting SI and other patients. Method Observational data were available for 3781 patients at entry to treatment, 2112 at three months and 777 for 12 months. Self-reported depressed mood and SI were assessed using items from the PHQ-9. Additional data included sociodemographic characteristics and self-reported well-being. Results 25% of the sample reported SI at treatment entry...
