Summary An increasing number of regions have or are considering legalising the sale of cannabis for adult use. Experience from tobacco and alcohol regulation has found that greater access to physical retail stores is positively associated with increased substance use and harm. Whether this association exists for cannabis is unclear. We completed a systematic review examining the association between cannabis retail store access and adverse health outcomes. We identified articles up until July 20, 2023 by searching four databases. We included studies examining the association between measures of cannabis store access and adverse outcomes: frequent or problematic cannabis use, healthcare encounters due to cannabis...

Key Points Question  What is the prevalence of past 3-month cannabis use, and what are the reasons for use among patients in a large health system? Findings  In this cross-sectional study of 175 734 patients, 17.0% reported cannabis use, among whom 34.7% had results indicative of moderate to high risk for cannabis use disorder. While most patients (76.1%) reported using cannabis to manage a health symptom, very few patients identified as medical cannabis users. Meaning  Given the high rates of cannabis use, especially for symptom management, and the high levels of disordered use, it is essential that health care systems implement routine screening of primary care patients.

Abstract Introduction: The use of medical cannabis (MC) to treat a host of conditions has expanded considerably in the United States; however, precise quantitative assessments of purchasing characteristics are unknown. This study sought to characterize the trends in MC purchases, US dollars spent, and type and amount purchased by demographic and clinical characteristics. Materials and Methods: This descriptive exploratory association study examined statewide MC registry data in Arkansas linked at the person level with statewide transaction data documenting each MC purchase. MC transaction data (May 11, 2019–August 31, 2022) were assessed to identify persons who could be linked...

Findings  In this systematic review and meta-analysis of 23 randomized clinical trials including 3612 participants, cannabinoids used for medical purposes in children and adolescents were associated with increased risk of adverse events, serious adverse events, and withdrawals due to adverse events compared with the control group. Meaning  The findings suggest that physicians considering cannabinoids for medical purposes in children and adolescents should weigh the risk and benefit profile of cannabinoids and available therapeutic options as well as the individual’s underlying...

Abstract: Objective: Previous research has demonstrated different cannabis-related outcomes depending on the goal of cannabis use (i.e., recreational, medical, a hybrid of both), underscoring the need to identify variables associated with specific goals of use, particularly in understudied populations. Method: This report used data from a national survey of menopausal individuals using nonprobability sampling. Respondents reporting current regular (≥1x/month) cannabis use (medical n = 35; recreational n = 61; and hybrid n = 102) were included in multivariate logistic regression analyses examining demographic, clinical (e.g., menopause-related symptomatology), and cannabis-related variables associated with the goal of cannabis use. Results: Overall, an increased number...

Abstract Background Wider availability of cannabis through medical and recreational legalization (MCL alone and RCL+MCL) has been hypothesized to contribute to reductions in opioid use, misuse, and related harms. We examined whether state adoption of cannabis laws was associated with changes in opioid outcomes overall and stratified by cannabis use. Methods Using National Survey on Drug Use and Health (NSDUH) data from 2015 to 2019, we estimated cannabis law associations with opioid (prescription opioid misuse and/or heroin use) misuse and use disorder. All logistic regression models (overall models and models stratified by cannabis use), included year...

ABSTRACT Sexual and gender minoritized (SGM) individuals in high-stigma areas may use cannabis to cope with unmet healthcare needs and elevated stress. Adults in Oklahoma (Mage = 43.9[SD = 16.8], 54.5% female, 71.4% non-Hispanic White) completed a cross-sectional survey (August-September 2022). Logistic regression examined the association of SGM identity (SGM or non-SGM) with past-year unmet healthcare need (yes/no). Logistic and linear regressions also examined main and interactive effects of SGM identity and unmet healthcare needs on past-month medical cannabis use and number of relaxation/tension-reduction reasons for cannabis use endorsed. Analyses were unadjusted and adjusted for sociodemographic and healthcare characteristics. In...

In the meantime, it is also prescribed for medical treatment in some countries. Tobacco smoke contains chemical carcinogens and particulate matter (PM) that are both harmful to health. Method: In this study, we investigated PM levels in second-hand smoke (SHS) of hand-tamped cannabis cigarettes compared to cigarettes with tubing tobacco and the 3R4F reference cigarette. Results: It could be demonstrated that the largest proportion of the particle mass is attributable to particles with a diameter of less than 1μm and that every tested cigarette emitted more PM...

Abstract Background: Cannabis is associated with the onset and persistence of psychotic disorders. Evidence suggests that accessibility of substances is associated with an increased risk of use-related harms. We sought to examine the effect of residing in proximity to non-medical cannabis retailers on the prevalence of health service use for psychosis. Methods: We conducted a cross-sectional study using linked health administrative data, and used geospatial analyses to determine whether people in Ontario, Canada (aged 14–60 years) resided within walking (1.6 km) or driving (5.0 km) distance of non-medical cannabis retailers (open as of February-2020). We identified outpatient visits, emergency department (ED) visits, and hospitalizations for psychotic disorders...

Although states that pass adult use laws report substantial declines in the number of registered medical patients, these laws expand the market, potentially enhancing patient benefits. However, research on federal adult use cannabis legislation in Canada suggests that adult use laws negatively impact medical patients. The purpose of this mixed-methods study was to examine medical cannabis patients’ perceptions of the impact of adult use cannabis laws in the US. We conducted an online survey with forced choice and open-ended questions in a...
