Cannabis has been reported to have effects on sleep and cognition. This review aims to summarize the recent literature on the ECB system, the role of cannabis and the ECB system on sleep regulation and cognition. Further, this review will identify existing gaps in knowledge and suggest potential targets for future research. Methods: We performed this review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Reports were identified by searching PubMed/MEDLINE, Embase, CINAHL, Web of Science, and PsycINFO...

One theory to explain this phenomenon is a potential substitution effect of MC for opioids. This study evaluated whether this substitution effect of MC for opioids also applies to other psychoactive medications. New England dispensary members (n = 1,513) completed an online survey about their medical history and MC experiences. Among respondents that regularly used opioids, over three-quarters (76.7%) indicated that they reduced their use since they started MC. This was significantly (p < 0.0001) greater than the...

Abstract Aims To assess associations among cannabis use, health-related quality of life, exercise, depression and sleep among a nationally representative sample of US adults living with cancer. Design A cross-sectional correlational study. Methods We used survey data from the 2016–2018 Behavioral Risk Factor Surveillance System. Analyses were considered for sample weights and the complex designs. Logistic regression was performed to assess associations among cannabis use (0, 1–19, vs. 20–30 [frequent] days), health-related quality of life (0–13 vs. ≥14 mentally or physically unhealthy days in the past 30 days; 0–13 vs. ≥14 functionally limited days), exercise, depression, and...

Abstract Insomnia or difficulty falling and or staying asleep is experienced by up to 30% of the general population. This randomised crossover double-blind placebo-controlled 6-week trial aimed to assess the tolerability and effectiveness of the Entoura-10:15 medicinal cannabis oil on sleep in adults with insomnia. A total of 29 participants with self-reported clinical insomnia completed the crossover trial. Participants were randomly allocated to receive placebo or active oil containing 10 mg/ml tetrahydrocannabinol (THC) and 15 mg/ml cannabidiol (CBD) over 2-weeks titrated 0.2-1.5 ml/day, followed by a 1-week wash-out period before crossover. Tolerability was assessed by daily diary. Effectiveness was measured by saliva midnight melatonin...

ABSTRACT Medical cannabis patients consistently report using cannabis as a substitute for prescription medications; however, little is known about individuals accessing cannabis through adult-use markets. A survey at two retail stores was conducted in Colorado, United States. Between August 2016 and October 2016, store staff asked customers if they wanted to participate and, if so, provided an electronic survey link. All customers reporting medical certification were excluded. Of 1,000 adult-use only customer respondents, 65% reported taking cannabis to relieve pain and 74% reported taking cannabis to promote sleep. Among respondents taking cannabis for pain, 80% reported...

However, CBD may present with a different activity compared with the psychotomimetic THC. Most typically, CBD is reported to be used in some medical conditions, including chronic pain. Conversely, the main aim of this systematic review is to assess and summarise the available body of evidence relating to both efficacy and safety of CBD as a treatment for psychiatric disorders, alone and/or in combination with other treatments. Eligible studies included randomized controlled trials (RCT) assessing the effect of CBD in a range...

Abstract Insomnia symptoms have been linked to problematic marijuana use among young adults, but the mechanism underlying this association and whether sex differences exist, remains unclear. Using cross-sectional data, this study examined negative mood as a mediator of the association between insomnia and marijuana problems among male and female college students. Undergraduate students (n = 267; 61% female) reporting marijuana use in the past month completed an online survey assessing insomnia symptoms, negative mood and marijuana problems. Controlling for relevant covariates, negative mood was examined as a mediator of the association between insomnia and marijuana problems using bootstrapped...

Design This was a (2018–2020) prospective cohort study of prenatally THC-exposed newborns. Maternal and Infant demographics, urine (UDS) and umbilical cord drug screening (UCDS) were recorded. A limited channel continuous aEEG was obtained within 48 h of birth. Statistical analysis included univariate, multivariate, and logistical regression. Results A total of 30 mother/infant dyads were enrolled. 60% (18/30) of neonates had abnormal aEEGs with sleep wake cycle (SWC) disturbances (p < 0.001). UCDS Carboxy-THC pg/g levels were similar in infants with abnormal [1758...

ABSTRACT OBJECTIVE BACKGROUND: The use of cannabis to improve sleep quality and treat sleep-related disorders has received increased attention due to the expanded legalization of cannabis for medical use in 36 states and Washington DC. Data on the effects of delta-9-tetrahydrocannabinol (THC), in combination with cannabinol (CBN), on sleep is preliminary; however, preclinical research indicates that CBN may prolong sleep and be particularly effective when combined with other cannabinoids. OBJECTIVE: The aim of this study was to evaluate the effect of a repeat-action tablet containing 10 mg THC and 5 mg CBN on sleep quality, sleep duration, and awakenings in participants (medical cannabis users)....

Abstract Study Objectives: Determine relationship between cannabis use with 1) expectations of cannabis being a sleep aid, 2) subjective sleep outcomes, and 3) the influence of age on these relationships. Methods: In 152 moderate cannabis users with a wide age range (67% female, mean age = 31.45, SD = 12.96, age range = 21–70; mean days of cannabis use in prior two weeks = 5.54, SD = 5.25) we examined the influence of cannabis use history and behaviors on expectations of cannabis being a sleep aid and sleep outcomes via the Pittsburgh Sleep Quality Index (PSQI)....
