Abstract Cannabis-infused foods are currently on the rise in markets all around the world. Meanwhile, there are concerns over the health implications for consumers. Studies have explored the therapeutic potential and nutritional and economic benefits of cannabis usage. Yet, the phytonutrients, processing methods, and health implications of cannabis-infused foods have not been well explored. This review evaluates existing evidence on the nutritional, processing, safety, and phytonutrient composition of cannabis-infused food products and their medicinal and functional prospects. Cannabis seeds contain the highest amount of dietary nutrients, while flowers contain the highest amount of bioactive constituents. Oils, butter, seeds, flowers, and leaf extracts are the...

Abstract Cannabis use is increasingly common, and with a growing number of jurisdictions implementing legalization frameworks, it is likely that providers will encounter more patients who use cannabis. Therefore, it is important for providers to understand the implications of cannabis use and practical considerations for the perioperative period. Cannabis affects multiple organ systems and may influence intraoperative anesthesia, as well as postoperative pain management. The effects of cannabis and key anesthetic considerations are reviewed here.

Key Points Question  Is prenatal exposure to cannabis associated with child outcomes? Findings  This cross-sectional analysis of 11 489 children (655 exposed to cannabis prenatally) found that prenatal cannabis exposure after maternal knowledge of pregnancy was associated with greater psychopathology during middle childhood, even after accounting for potentially confounding variables. Meaning  Prenatal cannabis exposure may increase risk for psychopathology; consistent with recent recommendations by the Surgeon General of the United States, these data suggest that cannabis use during pregnancy should be discouraged by clinicians and dispensaries. Abstract Importance  In light of increasing cannabis use among pregnant women, the US Surgeon General recently issued an advisory against the use of...

ABSTRACT Background: Chronic pain is common in the United States and prescribed opioid analgesics use for noncancer pain has increased dramatically in the past two decades, possibly accounting for the current opioid addiction epidemic. Co-morbid drug use in those prescribed opioid analgesics is common, but there are few data on polysubstance use patterns. Objective: We explored patterns of use of cigarette, alcohol, and illicit drugs in HIV-infected people with chronic pain who were prescribed opioid analgesics. Methods: We conducted a secondary data analysis of screening interviews conducted as part of a parent randomized trial of financial incentives to...

The medical literature contains a growing number of studies on cannabinoids as well as case studies and anecdotal reports suggesting therapeutic potential. Fifteen states have passed medical marijuana laws, but little is known about the growing population of patients who use marijuana medicinally. This article reports on a sample of 1,746 patients from a network of nine medical marijuana evaluation clinics in California. Patients completed a standardized medical history form; evaluating physicians completed standardized evaluation forms. From this data we...

Context: A number of studies have found that the use of cannabis and other psychoactive substances is associated with an earlier onset of psychotic illness. Objective: To establish the extent to which use of cannabis, alcohol, and other psychoactive substances affects the age at onset of psychosis by meta-analysis. Data Sources: Peer-reviewed publications in English reporting age at onset of psychotic illness in substanceusing and non–substance-using groups were located using searches of CINAHL, EMBASE, MEDLINE, PsycINFO, and ISI Web of Science. Study Selection: Studies in English comparing the age at onset of psychosis in cohorts of patients who use substances with age at onset...

Abstract Objective We created the Daily Sessions, Frequency, Age of Onset, and Quantity of Cannabis Use Inventory (DFAQ-CU) because the current lack of psychometrically sound inventories for measuring these dimensions of cannabis use has impeded research on the effects of cannabis in humans. Method A sample of 2,062 cannabis users completed the DFAQ-CU and was used to assess the DFAQ-CU’s factor structure and reliability. To assess validity, a subsample of 645 participants completed additional measures of cannabis dependence and problems (Marijuana Smoking History Questionnaire [MSHQ], Timeline Followback [TLFB], Cannabis Abuse Screening Test [CAST], Cannabis Use Disorders Identification Test Revised [CUDIT-R], Cannabis Use Problems Identification...

Key Points Question  Is there an association between prenatal cannabis exposure and maternal, perinatal, and neonatal outcomes? Findings  In this retrospective cohort study that included 661 617 pregnancies and 9427 reported cannabis users, the rate of preterm birth among reported cannabis users was 12% vs 6% in nonusers, a statistically significant difference. Meaning  Reported cannabis use in pregnancy was associated with significant increases in the rate of preterm birth following adjustment for confounding. Abstract Importance  Recent evidence suggests that cannabis use during pregnancy is increasing, although population-based data about perinatal outcomes following in utero exposure remain limited. Objective  To assess whether there are associations between self-reported prenatal cannabis use and...

Summary Background Variation in liability to cannabis use disorder has a strong genetic component (estimated twin and family heritability about 50–70%) and is associated with negative outcomes, including increased risk of psychopathology. The aim of the study was to conduct a large genome-wide association study (GWAS) to identify novel genetic variants associated with cannabis use disorder. Methods To conduct this GWAS meta-analysis of cannabis use disorder and identify associations with genetic loci, we used samples from the Psychiatric Genomics Consortium Substance Use Disorders working group, iPSYCH, and deCODE (20 916 case samples, 363 116 control samples in total), contrasting cannabis use disorder cases with controls. To...

Abstract Background Cancer patients experience multiple symptoms throughout their illness, and some report benefit from the use of cannabis. There are concerns that many patients are accessing products inappropriate for their situation and potentially putting themselves at risk. In the present study, we aimed to capture the prevalence of cannabis use among cancer patients at BC Cancer before recreational legalization in Canada and to identify the reasons that patients take cannabis, the various routes of administration they use, and the reasons that prior users stopped. Methods Patients were eligible if, on the selected study day (15 August 2018), they were scheduled for an appointment...
