Treatment of Neuropsychiatric Symptoms in Alzheimer’s Disease with a Cannabis-Based Magistral Formulation: An Open-Label Prospective Cohort Study

Neuropsychiatric symptoms (NPS) may be disruptive and problematic for patients with Alzheimer’s disease (AD) and for their caregivers. Cannabidiol (CBD) may be a safer alternative. The objective was to evaluate whether CBD-rich oil was effective, and safe in adults with NPS secondary to AD.

The Effect of Oil-Based Cannabis Extracts on Metabolic Parameters and Microbiota Composition of Mice Fed a Standard and a High-Fat Diet

The prevalence of obesity and obesity-related pathologies is lower in frequent cannabis users compared to non-users. It is well established that the endocannabinoid system has an important role in the development of obesity. We recently demonstrated that prolonged oral consumption of purified ∆-9 Tetrahydrocannabinol (THC), but not of cannabidiol (CBD), ameliorates diet-induced obesity and improves obesity-related metabolic complications in a high-fat diet mouse model. However, the effect of commercially available medical cannabis oils that contain numerous additional active molecules has not been examined. We tested herein the effects of THC- and CBD-enriched medical cannabis oils on obesity parameters and the gut microbiota composition of C57BL/6 male mice fed with either a high-fat or standard diet.

Edible marijuana and cycle ergometer exercise

There is extensive public and scientific interest in the influence of cannabis and the psychoactive cannabinoid, delta-9-tetrahydrocannabinol (THC), on exercise performance. Unfortunately, recent, up-to-date studies are lacking. The aim of the current study was to address the hypothesis that ingestion of edible marijuana, prior to exercise, would have unfavorable effects on the physiological response to exercise and on exercise performance.

Cannabidiol does not attenuate acute delta-9- tetrahydrocannabinol-induced attentional bias in healthy volunteers: A randomised, double-blind, cross-over study

To test how attentional bias and explicit liking are influenced by delta- 9-tetrahydrocannabinol (THC) and whether these effects are moderated by cannabidiol (CBD). Double-blind, randomised, within-subjects cross-over study. NIHR Wellcome Trust Clinical Research Facility at King’s College Hospital, London, United Kingdom.Participants/Cases: Forty-six infrequent cannabis users (cannabis use <1 per week).

Meta-analysis of the Therapeutic Impact of Cannabinoids in Inflammatory Bowel Disease

Breast cancer is the most frequently diagnosed cancer and the leading cause of death by cancer among women worldwide. The prognosis of the disease and patients’ response to different types of therapies varies in different subgroups of this heterogeneous disease. The subgroups are based on histological and molecular characteristics of the tumor, especially the expression of estrogen (ER) and progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). Hormone-dependent breast cancer, determined predominantly by the presence of ER, is the most common type of breast cancer. Patients with hormone-dependent breast cancer have an available targeted therapy, however, tumor cells can develop resistance to the therapy, which is a major obstacle limiting the success of treatment and enabling relapse to metastatic disease. …

Effects of concomitant use of THC and irinotecan on tumour growth and biochemical markers in a syngeneic mouse model of colon cancer

Clinical treatment with the antineoplastic drug irinotecan (IRI) is often hindered by side effects that significantly reduce the quality of life of treated patients. Due to the growing public support for products with Δ9-tetrahydrocannabinol (THC), even though relevant scientific literature does not provide clear evidence of their high antitumour potential, some cancer patients take unregistered preparations containing up to 80 % THC. This study was conducted on a syngeneic colorectal cancer mouse model to test the efficiency and safety of concomitant treatment with IRI and THC. Male BALB/c mice subcutaneously injected with CT26 cells were receiving 60 mg/kg of IRI intraperitoneally on day 1 and 5 of treatment and/or 7 mg/kg of THC by gavage a day for 7 days. Treatment responses were evaluated based on changes in body, brain, and liver weight, tumour growth, blood cholinesterase activity, and oxidative stress parameters. Irinotecan’s systemic toxicity was evidenced by weight loss and high oxidative stress. The important finding of this study is that combining THC with IRI diminishes IRI efficiency in inhibiting tumour growth. However, further studies, focused on more subtle molecular methods in tumour tissue and analytical analysis of IRI and THC distribution in tumour-bearing mice, are needed to prove our observations.

Decreased melanoma CSF-1 secretion by Cannabigerol treatment reprograms regulatory myeloid cells and reduces tumor progression

During solid tumor progression, the tumor microenvironment (TME) evolves into a highly immunosuppressive milieu. Key players in the immunosuppressive environment are regulatory myeloid cells, including myeloid-derived suppressor cells (MDSCs) and tumor-associated macrophages (TAMs), which are recruited and activated via tumor-secreted cytokines such as colony-stimulating factor 1 (CSF-1). Therefore, the depletion of tumor-secreted cytokines is a leading anticancer strategy. Here, we found that CSF-1 secretion by melanoma cells is decreased following treatment with Cannabis extracts. Cannabigerol (CBG) was identified as the bioactive cannabinoid responsible for the effects.

Quality of Life Among Patients Using Cannabis to Manage Anxiety: A Longitudinal Observational Study

As our knowledge and understanding of the therapeutic role of cannabis evolve through increased research, cannabis products are increasingly being used as a treatment for several medical conditions. Recent evidence suggests that cannabis may exert anxiolytic effects, which has led to considerable interest in using cannabis for the management of anxiety. Accordingly, there is a need to examine the effect of cannabis use on health-related quality of life (HRQoL) in patients with anxiety. The aim of this observational study was to measure the HRQoL for 1 year of 60 participants who used medical cannabis products primarily to manage their anxiety symptoms.

Effects of Two Cannabidiol Oil Products on Self-Reported Stress Relief: A Quasi-Experimental Study

Estimated rates of past-month cannabidiol (CBD) use in the general public are 13–26% and emerging research examines CBD as a potential adjunct treatment for several medical conditions, including stress-related disorders (e.g., depression, anxiety, and chronic pain). However, little is known about the effects of different CBD products on self-reported stress. The present study compared the effects of two delta-9-tetrahydrocannabinol (THC)-free CBD tincture products – (1) an isolate CBD oil and (2) a broad spectrum CBD oil – on self-ratings of effectiveness of the product and ability to manage stress.

Relief in Gastrointestinal Symptoms with Medical Marijuana Over 1 Year

Subjective improvement in gastrointestinal (GI) symptoms was assessed among patients using medical marijuana (MMJ).Participants completed surveys at 0 days, 30 days, 6 months, and 12 months with questions about the severity of their GI symptoms on a scale from 1 (mild) to 3 (severe).

Prevalence of Metabolic Syndrome Among Emerging Adult Cannabis Users by Race/Ethnicity: Analysis of the 2009-2018 National Health and Nutrition Examination Surveys

Association between cannabis use and metabolic syndrome (MetS) has been documented; yet variation by race/ethnicity is understudied. We examined cannabis use and MetS by race/ethnicity among emerging adults (18-25 years old), the age group with the highest prevalence of cannabis use.

Understanding the epidemiology and perceived efficacy of cannabis use in patients with chronic musculoskeletal pain

The belief that cannabis has analgesic and anti-inflammatory properties continues to attract patients with chronic musculoskeletal (MSK) pain towards its use. However, the role that cannabis will play in the management of chronic MSK pain remains to be determined. This study examined 1) the rate, patterns of use, and self-reported efficacy of cannabis use among patients with chronic MSK pain and 2) the interest and potential barriers to cannabis use among patients with chronic MSK pain not currently using cannabis.
