Neighborhood cannabis dispensary availability may increase problematic use. State and local studies suggest that cannabis dispensary availability may be correlated with neighborhood sociodemographic characteristics. We provide a national-level examination of census tract (CT) sociodemographic characteristic correlates with the availability of cannabis dispensaries in 18 U.S. states that have legalized adult recreational cannabis use. <b>Methods:</b> We downloaded the locations of cannabis dispensaries (<i>N</i> = 3,167) from Weedmaps in November 2021. We downloaded ethnic, racial, and socioeconomic estimates from the U.S. Census and categorized CTs into quintiles (Q), where Q1 represents the CTs with the lowest percentage of a variable and Q5 represents CTs with the highest. We fit unadjusted generalized linear mixed models to examine associations between quintiles of each sociodemographic characteristic and the presence of at least one dispensary (vs. none). <b>Results:</b> CTs with a greater percentage of Black residents had a higher odds of having at least one cannabis dispensary (vs. none) across all quintiles. For example, compared to CTs with the lowest percentage of Black residents (Q1), CTs with the greatest percentage of Black residents (Q5) had 2.07 (95% CI: 1.70-2.52) times the odds of having at least one dispensary versus none. We observed a similar pattern of a greater likelihood of a CT having a dispensary (vs. none) as the percentage of Hispanic/Latine residents and percentage of individuals living below the federal poverty line increased across all quintiles. In contrast, as the percentage of homeowner-occupied housing increased across all quintiles, there were lower odds of having at least one dispensary (vs. none). For example, CTs with the highest percentage of homeowner-occupied housing (vs. lowest) had 0.21 (95% CI: 0.17-0.26) times the odds of having at least one dispensary vs. none. <b>Discussion/Conclusions:</b> Differences in cannabis dispensary availability exist by neighborhood sociodemographic composition.

Mean doses (mg) of primary cannabinoids in the active drug conditions were: 1 mg/kg condition (CBD = 41.1, CBDA = 43.7, THC = 2.2, THCA = 1.6), 2 mg/kg condition (CBD = 73.4, CBDA = 77.9, THC = 3.9, THCA = 2.9), and 4 mg/kg condition (CBD = 134.5, CBDA = 142.8, THC = 7.2, THCA = 5.3).

The purpose of this study was to estimate the prevalence of cannabis use for symptom management of chronic health conditions during the COVID-19 pandemic. <b>Methods:</b> The COVID-19 Cannabis Health Study is an ongoing study among adults ≥18 who self-report cannabis use. Analyses included 1,466 responses received between March 21, 2020, and March 23, 2022, from participants who self-reported cannabis use and a chronic health condition. We examined comorbidities, symptoms managed with cannabis during the COVID-19 pandemic, and fear regarding COVID-19 diagnosis and transmission using the COVID-19 Cannabis Health Questionnaire. Descriptive statistics, Chi-squared, and T-tests were conducted. Results were stratified by those who reported using cannabis to manage a chronic health condition (medicinal cannabis user, <i>n</i> = 1,333) and those who did not use cannabis to manage chronic health condition (non-medicinal cannabis user, <i>n</i> = 133). <b>Results:</b> Most (90.9%, <i>n</i> = 1,333) of the total sample (mean age: 47.1 years [standard deviations {SD} = 15.0]) reported using cannabis to manage a chronic health condition, of which 46.1% (<i>n</i> = 615) reported having a medical card/recommendation, and 4.6% received recommendations to use cannabis to manage COVID-19 from health professionals. There were significant differences in age, gender, race/ethnicity, and education by medicinal cannabis use status. Comorbidities prevalent among medicinal cannabis consumers were mental health-related (66.1%), pain (58.5%), cardiometabolic-related (30.5%), immune-related (21.9%), and respiratory-related (20.8%). The most reported symptoms self-managed with cannabis during the pandemic were sleep (69.2%), chronic noncancer pain (49.7%), acute pain (46.5%), headaches/migraines (39.0%), muscle spasms (33.6%), nausea/vomiting (30.6%), and appetite stimulant (29.9%). There were no statistical differences in COVID-19 testing, fear of diagnosis, fear of transmission, or isolation due to COVID-19 between medicinal and nonmedicinal cannabis consumers in this sample. <b>Conclusions:</b> The perceived therapeutic benefit of cannabis during the COVID-19 pandemic is evident by the high prevalence of adults who reported using cannabis for medicinal reasons despite no recommendation from their health provider.

Selected studies included randomized controlled trials, retrospective cohort studies, uncontrolled before-after studies, and observational retrospective studies in English, French, or Spanish that reported gastrointestinal adverse events in the pediatric population under therapeutic cannabinoid interventions. The study was registered with PROSPERO and followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guidelines.

While there is existing empirical evidence supporting these effects of cannabis use, little is known about the extent to which these effects result from pharmacological versus expectancy factors. We evaluated the associations between participants' cannabis expectancies and their acute self-reported reactions after using legal market forms of cannabis with varying levels of cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC) in three domains: anxiety, depression, and pain. <b>Methods:</b> Fifty-five flower and 101 edible cannabis users were randomly assigned and asked to purchase at a local dispensary one of three products containing varying levels of CBD and THC. Participants completed a baseline assessment where they reported expectancies about general health effects of cannabis use and an experimental mobile laboratory assessment where they administered their assigned products. Edible users also reported their domain-specific expectancies about cannabis use in improving anxiety, depression, and pain. Following administration, participants completed acute indicators of anxiety, depression, and pain operationalized through subjective acute tension, elation, and a single-item measure of pain. <b>Results:</b> Among flower users, more positive expectancies for cannabis to improve general health were correlated with greater reductions in tension at acute post-use.
