Abstract Background and Objectives There is a need to know more about cannabis use among terminally diagnosed older adults, specifically whether it operates as a complement or alternative to palliative care. The objective is to explore differences among the terminal illness population within the Illinois Medical Cannabis Program (IMCP) by their use of palliative care. Research Design and Methods The study uses primary, cross-sectional survey data from 708 terminally diagnosed patients, residing in Illinois, and enrolled in the IMCP. We compared the sample on palliative care utilization through logistic regression models, examined associations between palliative care and self-reported outcome improvements using ordinary least squares...

Abstract Background Daily use of marijuana is rising in adolescents, along with consumption of high potency marijuana products (high % Δ-9-tetrahydrocannabinol or THC). These dual, related trends have opened gaps in understanding the long-term effects of daily consumption of a high dose of THC in adolescents and whether a therapeutic dose of cannabidiol (CBD) modulates THC effects. Methods Adolescent squirrel monkeys (Saimiri boliviensis) were treated daily for four months with vehicle (n = 4), a high THC dose (1 mg/kg i.m.; n = 4), or THC + CBD (1 mg/kg +3 mg/kg i.m.; n = 4),...

While THC can induce perceptual distortions and anxiogenic effects, CBD displays antipsychotic and anxiolytic properties. A key brain region responsible for regulation of cognition and affect, the medial prefrontal cortex (PFC), is strongly modulated by cannabinoids, suggesting that these dissociable THC/CBD-dependent effects may involve functional and molecular interplay within the PFC. The primary aim of this study was to investigate potential interactions and molecular substrates involved in PFC-mediated effects of THC and CBD on differential cognitive and affective behavioural processing. Male Sprague Dawley...

Chronic pelvic pain often develops in the setting of endometriosis, interstitial cystitis/bladder pain syndrome, and vulvodynia. Cannabinoids are a promising treatment modality for non-cancer chronic pain, but have not been studied in women with chronic pelvic pain nor in specific chronic pelvic pain conditions. This review focuses on the interaction of the endocannabinoid system with the menstrual cycles, with endometriotic lesions, and within the bladder. Furthermore, it provides a brief overview of existing literature of the effects of endocannabinoids on chronic pain generally,...

Abstract Background: People with spinal cord injuries (SCI) commonly experience pain and spasticity; limitations of current treatments have generated interest in cannabis as a possible therapy. Objectives: We conducted this systematic review to: 1) examine usage patterns and reasons for cannabinoid use, and 2) determine the treatment efficacy and safety of cannabinoid use in people with SCI. Methods: PubMed, Embase, Web of Science and Cumulative Index to Nursing and Allied Health Literature databases were queried for keywords related to SCI and cannabinoids. Results: 7,232 studies were screened, and 34 were included in this systematic review. Though...

Management of FIASs is clinically challenging, and new interventions are needed for better seizure control. The amygdala-kindling model is a preclinical model of FIASs with secondary generalization. The present study assessed the efficacy of cannabidiol (CBD), ∆9-tetrahydrocannabinol (THC), and a combination of CBD and THC in a 15:1 ratio at suppressing focal and secondarily generalized seizures in the amygdala-kindled rat. Methods Fully kindled, male Sprague Dawley rats, with bipolar electrodes implanted in the right amygdala,...

Abstract Agitation is a common neuropsychiatric symptom of Alzheimer's disease (AD) that greatly impacts quality of life and amplifies caregiver burden. Agitation in AD may be associated with volume loss in the anterior cingulate cortex, posterior cingulate cortex, insula, amygdala, and frontal cortex, as well as with degeneration of monoaminergic neurotransmission, disrupted circadian rhythms, and frailty. Current pharmacologic options have troubling safety concerns and only modest efficacy. There is increasing interest in cannabinoids as promising agents due to preclinical and early clinical research that suggest cannabinoids can elicit anxiolytic, antidepressant, and/or anti-inflammatory effects. Cannabinoids may relieve...

Abstract Goal and Background: A number of studies have investigated the effectiveness of cannabis or cannabinoids for treatment of inflammatory bowel diseases (IBD). We aimed to systematically analyze their effect in in the treatment of IBD patients. Study: We included randomized controlled trials and nonrandomized studies analyzing IBD patients of any age using cannabi(noid)s. Two reviewers searched 3 databases until August 13, 2019. Primary outcome was clinical remission and secondary outcomes included inflammatory biomarkers, symptom improvement, quality of life (QoL) scores, and hospital outcomes. Risk of bias was assessed according to study type. The meta-analyses were...

For decades, cannabis has been known to cause physical effects on the human body, including increasing appetite, which may be beneficial in the treatment of AN. Objective To systematically review the literature for evidence of an effect of cannabinoids on (1) weight gain, and (2) other outcomes, in AN. Method A systematic review was done using three databases Embase, PubMed and Psychinfo. The review was registered in PROSPERO with ID number CRD42019141293 and was done...

Abstract The use and abuse of cannabis can be associated with significant pathophysiology, however, it remains unclear whether (1) acute administration of Δ-9-tetrahydrocannabinol (THC) during early adulthood alters the cannabinoid type 1 (CB1) receptor localization and expression in cells of the brain, and (2) THC produces structural brain changes. Here we use electron microscopy and a highly sensitive pre-embedding immunogold method to examine CB1 receptors in the hippocampus cornu ammonis subfield 1 (CA1) 30 min after male mice were exposed to a single THC injection (5 mg/kg). The findings show that acute exposure to THC can significantly decrease...
