Abstract Objective: People with ADHD are more likely to use cannabis but little is known about the effects of cannabis on ADHD symptoms, ADHD medication side effects, or ADHD-related executive dysfunction. Method: Students (n = 1,738) completed an online survey containing measures of ADHD symptoms, cannabis use, perceived effects of cannabis on ADHD symptoms and medication side effects, as well as executive dysfunction. Results: Participants with ADHD who have used cannabis reported that cannabis has acute beneficial effects on many symptoms of ADHD (e.g., hyperactivity, impulsivity). Further, they perceived cannabis to improve most of their medication side effects...

To create an evidenced-based point of view for patients and physicians, we performed a systematic review of randomized controlled trials (RCT) on the use of cannabinoids in MD. The seven RCTs found on PD used different cannabis formulations. No improvement of motor symptoms was shown in any of the two RCTs with this as primary outcome (PO), but in the nabilone group, an improvement in quality of life was documented. Of the three RCTs having levodopa-induced dyskinesia as PO,...

Abstract Objective The current study examined the unique predictive ability of tolerance of specific negative affective states in relation to frequency of past-month cannabis use and coping-oriented cannabis use motives. Participants: 416 undergraduates who reported past 30 day cannabis use (65.1% female; Mage = 19.46, SD = 2.56). Methods: Participants completed self-report questionnaires for course credit. Results: After accounting for the effects of sex, negative affectivity, and tolerance of other specific negative affective states, lower levels of tolerance for sadness, but not any other negative affective states, significantly predicted more frequent cannabis use in the past 30 days (1.1% unique...

Insomnia and sleep disorders are among the most common conditions for which patients report using cannabis. Current research shows cannabis may have a beneficial effect in sleep disorders and may improve patient-reported sleep scores. Methods: A retrospective chart review was conducted at Hybrid Pharm community pharmacy in Ottawa, Ontario, and included patients who were interested in, or already using, medical cannabis for sleep disorders. A qualitative, exploratory approach was taken to evaluate the descriptive efficacy and safety of...

High levels of illicit cannabis use for therapeutic purposes have been previously reported by endometriosis patients in Australia and New Zealand (NZ). Although access to legal medicinal cannabis (MC) is available through medical prescription via multiple federal schemes, significant barriers to patient access remain. Methods: An anonymous cross-sectional online survey was developed and distributed through social media via endometriosis advocacy groups worldwide. Respondents were asked about legal versus illicit cannabis usage, their understanding of access pathways and legal status, and their...

However, the relationship between cannabis use and suicidal behavior remains relatively unexplored and this paper aims to unify existing literature on the topic. A systematic review was conducted using MEDLINE, Embase, PsycINFO and LILACS databases with a supplementary search to identify cohort articles published up to January 2020, with no age delimitation for the samples. This review aimed to address the relationship between cannabis use and suicidal behavior, defined as suicidal ideation, attempted suicide or completed suicide. Twenty-two articles were...

This could explain the reported link between cannabis and cardiovascular events including stroke and myocardial infarction. This analysis included 7,159 participants (age 37.8 ± 12.4 years, 48.6% men, and 61.5% Caucasian) from the National Health and Nutrition Examination Survey years 2011 to 2018. Cannabis use was defined by self-report. Participants with a history of stroke or myocardial infarction were excluded. Composite CVD risk was assessed using the American College of Cardiology/American Heart Association 10-year atherosclerotic cardiovascular risk (ASCVD) score. Participants were classified...

The reasons, experienced effects, and prevalence of use are unknown in the European general oncological population. Methods Adult patients with cancer attending outpatient oncology clinics were invited to participate in a cross-sectional survey. The questionnaire consisted of sociodemographic questions, validated scales on quality of life, neuropathy, anxiety and depression as well as questions regarding use of cannabis. Results The overall response rate was 83% (2839 patients) and 13% of patients were using or had used cannabis during their treatment. Rate of use was higher in smokers...

Abstract Objectives The current study examined whether cannabis use frequency and cannabis-related problem severity (as per the Cannabis Use Disorder Identification Test-Revised) predicted outcomes of cognitive behavioural therapy (CBT) for anxiety and related disorders. It was predicted that greater frequency of cannabis use and greater cannabis-related problem severity would be associated with dampened treatment outcomes compared to less severe cannabis use presentations. Methods Participants were 253 adults seeking treatment for anxiety and related disorders. Cannabis use was categorized as non-use (n = 135), infrequent use (using monthly to 4 times per month; n = 45), and frequent use (using 2 or more times per week; n = 73). Individuals who reported using cannabis completed...

Abstract Objectives: We measure for the first time how commercially available Cannabis flower products affect feelings of fatigue. Methods: A total of 1,224 people recorded 3,922 Cannabis flower self-administration sessions between June 6, 2016, and August 7, 2019, using the Releaf App. Usage sessions included real-time subjective changes in fatigue intensity levels prior to and following Cannabis consumption, Cannabis flower characteristics (labeled phenotype, cannabinoid potency levels), combustion method, and any potential experienced side effects. Results: On average, 91.94% of people experienced decreased fatigue following consumption with an average symptom intensity reduction of 3.48 points on a 0–10 visual analog scale (SD = 2.70, d = 1.60, p < 0.001). While labeled plant phenotypes (“C. indica,” “C. sativa,” or “hybrid”) did not...
