Abstract Purpose of Review Sleep impairment due to chronic pain is linked to functional impairment and often inadequately addressed with current treatments leading some to seek alternative therapies, including cannabis. The factors associated with chronic pain and sleep impairments are disproportionately experienced by individuals from racial/ethnic minorities, of low socioeconomic status, who live in noisy, chaotic neighborhoods, and who have poor health care access. Recent Findings First, we describe the limited evidence for cannabis to manage pain and pain-related sleep impairment. Second, we highlight how research might exacerbate health inequities due to systematic biases in the...

Highlights Prospective study with sleep and mood assessment in people with epilepsy (PWE) reporting cannabis use. Self-reported sleep quality, but not sleep quality and quantity from PSG was significantly better among PWE using cannabis. Depression and excessive daytime sleepiness were highly prevalent, with linear correlation between them, but not with cannabis use. Abstract Objective Interest in anti-seizure properties of cannabinoids is increasing, with the rise in prevalence of recreational and medical cannabis use, especially across Canada. In a recent study on people with epilepsy (PWE), cannabis use showed a strong association with poor psychosocial health. Sleep and mood comorbidities are highly prevalent in epilepsy,...

Abstract Introduction Cannabinoids are being used by patients to help with chronic pain management and to address the 2 primary chronic pain comorbidities of anxiety and sleep disturbance. It is necessary to understand the biphasic effects of cannabinoids to improve treatment of this symptom triad. Methods A scoping review was conducted to identify whether biphasic effects of cannabinoids on pain severity, anxiolysis, and sleep disturbance have been reported. The search included the Embase, Biosis, and Medline databases of clinical literature published between 1970 and 2021. The inclusion criteria were (1) adults more than 18 years of age, (2) data or discussion of dose effects associated...

This study aims to determine the impact of nonmedical whole plant cannabis use 3 hours prior to sleep and measured cannabis metabolites on polysomnogram measures. Methods: This is a cross-sectional study of 177 healthy adults who provided detailed cannabis use history, underwent a 1-night home sleep test and had measurement of 11 plasma and urinary cannabinoids, quantified using mass spectroscopy, the morning after the home sleep test. Multivariable models were used to assess the relationship...

Abstract Background Research on cannabis-based medicinal products (CBMPs) in anxiety remains inconclusive due to a paucity of high-quality evidence. Studies indicate a bidirectional relationship between generalized anxiety disorder (GAD) and sleep disruption, but it is unclear how this affects CBMP treatment outcomes. This study aims to compare the patient-reported outcome measures (PROMs) of patients prescribed CBMPs for GAD, with and without impaired sleep. Methods Changes in PROMs were recorded from baseline to 1, 3, 6, and 12 months between those with impaired or unimpaired sleep. Multivariate logistic regression was applied to compare factors associated with a clinically significant improvement in GAD-7 at 12 months. Secondary outcomes...

Abstract Introduction Chronic pain (CP) affects 35.0%–51.3% of the UK population, with 67%–88% reporting sleep disturbances. Cannabis-based medicinal products (CBMPs) have shown therapeutic potential in managing CP. Evidence suggests poor sleep worsens pain perception; therefore, this study aimed to assess patient-reported outcome measures (PROMs) following CBMP treatment in CP patients with and without co-morbid sleep impairment. Methods A prospective cohort study of CP patients from the UK Medical Cannabis Registry was conducted. Participants were separated by baseline single-item sleep quality scale (SQS) score into sleep impaired (SQS ≤3) and unimpaired (SQS ≥4) cohorts. The primary outcome assessed changes in PROMs from baseline to 1-,...

Abstract Objectives: This study sought to extend research on the relation between depression symptoms and problematic cannabis use by evaluating the potential moderating role of perceived sleep quality among medical cannabis users. Methods: This employed a cross-sectional design. The sample consisted of 162 adults (mean age = 42.05 years, SD = 14.8; 22% female), with current recommendations from a doctor for medical cannabis, recruited from a medical cannabis dispensary. Results: Consistent with previous research, individuals with heightened depression symptoms had greater problematic cannabis use. In addition, perceived sleep quality moderated this relation, such that depression symptoms differentially related to problematic cannabis...

Cannabidiol (CBD) has drown much attention as a non-addictive psychoactive component in Cannabis sativa extract. However, the effects of CBD on sleep architecture and it’s acting mechanism remains unclear. In the present study, we evaluated the sedative-hypnotic effect of cannabidiol (CBD), assessed the effects of CBD on sleep using a wireless physiological telemetry system. We further explored the therapeutic effects of CBD using 4-chloro-dl-phenylalanine (PCPA) induced insomnia model and changes in sleep latency, sleep duration and intestinal flora were evaluated. CBD shortened sleep latency and increases sleep...

The primary objective of this study was to evaluate the effects of an oral CBD-terpene formulation on sleep physiology in individuals with insomnia. Methods: In this double-blind, placebo-controlled, randomized clinical trial, 125 individuals with insomnia received an oral administration of CBD (300 mg) and terpenes (1 mg each of linalool, myrcene, phytol, limonene, α-terpinene, α-terpineol, α-pinene, and β-caryophyllene) for ≥ 4 days/week over 4 weeks using a crossover design. The study medication was devoid of Δ9-tetrahydrocannabinol (Δ9-THC)....

CBD is often used by patients for the management of insomnia, yet research supporting CBDs effectiveness as a treatment for insomnia is inadequate. Objective: The objective of this review was to critically evaluate the literature regarding the therapeutic benefits of CBD in the management of insomnia. Methods: A comprehensive search of the following databases from inception to December 29, 2021, was conducted: Ovid MEDLINE® and Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily, Ovid Embase, Ovid Cochrane Central...
