Abstract Recent studies have shown that there is also biological plausibility for a possible relationship between periodontal disease and Cannabis use, thus the aim of this study was to investigate whether the use of Cannabis is associated with periodontitis. Electronic searches were performed in PubMed, Scopus, ISI-Web of Science, BVS-Virtual health library and Scielo without restrictions. Search strategy was performed using relevant keywords considering the structure of each database. Longitudinal and cross-sectional studies that investigated the association between the use of Cannabis and periodontal disease were included. Meta-analyses and sensitivity analysis were conducted. A total of...

Abstract The prior medical literature offers little guidance as to how pain relief and side effect manifestation may vary across commonly used and commercially available cannabis product types. We used the largest dataset in the United States of real-time responses to and side effect reporting from patient-directed cannabis consumption sessions for the treatment of pain under naturalistic conditions in order to identify how cannabis affects momentary pain intensity levels and which product characteristics are the best predictors of therapeutic pain relief. Between 06/06/2016 and 10/24/2018, 2987 people used the ReleafApp to record 20,513 cannabis administration measuring cannabis’ effects...

However, reports on long-term outcomes are lacking. This prospective, observational study assessed the effects of licensed cannabis use among patients with inflammatory bowel disease. Methods  Dose and mode of consumption, adverse events, use of other medications, and long-term effects were evaluated among 127 patients with inflammatory bowel disease using legalized medical cannabis. Blood count, albumin, and C-reactive protein were assessed before, 1 month, and at least 1 year after medical cannabis therapy was initiated. Questionnaires on disease activity, patient function, and...

Understanding behaviors contributing to DUIC can inform prevention efforts. We evaluated three past 6-month DUIC behaviors among medical cannabis users with chronic pain. Methods Adults (N = 790) seeking medical cannabis certification or recertification for moderate/severe pain were recruited from February 2014 through June 2015 at Michigan medical cannabis clinics. About half of participants were male (52%) and 81% were White; their Mean age was 45.8 years. Participants completed survey measures of DUIC (driving within 2 h of use, driving while “a little high,” and...

Abstract Chronic pain is common, costly, and challenging to treat. Many individuals with chronic pain have turned to cannabis as an alternative form of pain management. We report results from an ongoing, online survey of medical cannabis users with chronic pain nationwide about how cannabis affects pain management, health, and pain medication use. We also examined whether and how these parameters were affected by concomitant recreational use, and duration of use (novice: <1 year vs experienced: ≥1 year). There were 1,321 participants (59% female, 54% ≥50 years old) who completed the survey. Consistent with other observational studies, approximately 80% reported substituting cannabis for traditional...

Abstract The core symptoms and co-morbidities associated with autism spectrum disorders (ASD) affect daily living and quality of life. Existing pharmacological interventions are only able to attenuate some related symptoms but are unable to address the underlying etiologies associated with ASD. Anecdotal evidence, which claims benefit from the use of cannabis to treat symptoms among this population, has been gaining popularity as families seek solutions. This paper analyzed recent peer-reviewed literature to identify the current state of evidence regarding cannabis use for the ASD population. Systematic reviews, reports, and experimental studies were assessed to understand the current extent and nature of the evidence on...

Abstract There is significant interest among patients and providers in using cannabis (marijuana) and its derivatives to treat a number of chronic illnesses, including inflammatory bowel disease. Despite the Schedule I classification of cannabis by the federal government, state governments have sought ways to make cannabis available for specific medical conditions, and some states have legalized cannabis outright. This white paper summarizes the preclinical data, clinical data, safety data, and the regulatory landscape as they apply to medical cannabis use in inflammatory bowel disease. Animal models of cannabinoid chemistry and physiology give evidence of anti-inflammatory, antidiarrheal, and nociceptive-limiting properties. Human studies have found benefit...

Abstract Objective: The study sought to describe a Canadian sample of university students’ medicinal use of cannabis, including prevalence of cannabis use disorder (CUD) and replacement of traditional treatments with cannabis. Method: A random sample of 4000 university students was asked to complete a cross-sectional web-based survey. The survey was completed by 2212 (average age 23.2 years, SD = 5.2 years), representing a 55.3% response rate. To be eligible, students had to be enrolled in a class on campus and were 18 years or older. Result: Half (52%) of respondents used cannabis at least once in their lifetime, with ∼11% reporting medicinal cannabis use....

Key Points Question  To what extent is the association between cannabis use and psychotic-like experiences attributable to predispositional (ie, shared genetic) or to individual-specific factors? Findings  This cross-sectional study of twin and nontwin sibling pairs analyzed a combined sample comprising 4674 individuals and found significant evidence for shared genetic factors between cannabis involvement and psychotic-like experiences. After accounting for genetic overlap, frequent users of cannabis were more likely to report psychotic-like experiences than relatives who used cannabis less frequently. Meaning  Although shared genetic influences are important, person-specific factors also appear to influence the association between cannabis involvement and psychotic-like...

Abstract The evidence for cannabis’s treatment efficacy across different conditions varies widely, and comprehensive data on the conditions for which people use cannabis are lacking. We analyzed state registry data to provide nationwide estimates characterizing the qualifying conditions for which patients are licensed to use cannabis medically. We also compared the prevalence of medical cannabis qualifying conditions to recent evidence from the National Academies of Sciences, Engineering, and Medicine report on cannabis’s efficacy in treating each condition. Twenty states and the District of Columbia had available registry data on patient numbers, and fifteen states had data on patient-reported qualifying conditions. Chronic pain is currently...
