Newest firstObjective The objective of this study was to examine whether cannabis exposure calls to the British Columbia Drug and Poison Information Centre (DPIC) were impacted by the legalization of non-medical cannabis in Canada. Methods We fit interrupted time series models to monthly counts of cannabis cases from 2013 to 2021, stratified by age and cannabis form. We set the intervention month to October 2018 legalization…
Open article record in new tab ↗Purpose This study used data from the National Health and Nutrition Examination Survey (NHANES) to examine associations between the use of four illicit drugs (cocaine, heroin, marijuana, and methamphetamine) and the dental caries experience among adults in the US using the Decayed, Missing and Filled Teeth (DMFT) index. Materials and methods Data from NHANES 2017-2018, a cross-sectional study that included adults…
The interactive effects of HIV and marijuana (MJ) on the brain remain largely unknown, despite the prevalence of cognitive implications in this population. This study examined the impacts of HIV and MJ on brain networks crucial for normal cognitive function. Functional MRI data and a battery of neuropsychological tests from 237 HIV+ and HIV- adults aged 25-59 years, stratified by MJ use, were collected. The follow…
Open article record in new tab ↗Background: Several factors influence reasons for cannabis use in the U.S. This study examines reasons for cannabis use (recreational only, medical only, both) and their frequency of use in association with demographic variables, health-risk behaviors, legal status, and chronic disease. Methods: We performed a cross-sectional analysis of 466,355 adults (aged ≥18) in the 2018-2021 BRFSS surveys in areas that admini…
Open article record in new tab ↗Background The flower strains of cannabis are an important attribute that determines product appeal and health impacts. However, there is a lack of surveillance of cannabis strains as the marketplace expands in response to the growing legalization of recreational and medical cannabis. Objective This study aimed to analyze cannabis strains and their growth using existing data from user-generated reviews on the Leaf…
Open article record in new tab ↗Background Individuals with chronic conditions often use opioids for pain and the broadening legalization of marijuana and its potential analgesic effects may prompt some individuals to use marijuana as an additional option. Both substances have been individually linked to adverse effects on major depressive disorder (MDD), but little is known about their co-use. This study examined the association between co-use…
Background and Objectives: One of the strongest early factors influencing later psychoactive substance use is adverse childhood experiences (ACEs). Studies investigate a variety of adverse experiences in relation to substance use, yet not all adverse childhood experiences are equal in intensity and harm. Our study aimed to address this gap by examining in detail the associations between individual ACEs, broader AC…
Open article record in new tab ↗AbstractAcute cannabis use and its primary psychoactive constituent tetrahydrocannabinol (THC) can induce postural dizziness, indicating increased risk of orthostatic instability. However, it is unknown if vulnerabilities persist the morning after bedtime THC consumption. This study investigated the influence of bedtime THC consumption on cardiovascular variables during an orthostatic challenge. Nine individuals w…
PurposeCannabis use disorder (CUD) is increasingly prevalent among surgical patients, yet its association with postoperative complications following breast surgery remains poorly characterized. This study compared rates of surgical site complications and emergency department (ED) utilization after mastopexy and reduction mammaplasty between patients with and without documented CUD.MethodsA retrospective, propensit…
Open article record in new tab ↗Background and hypothesis Affective instability (AffI) is associated with psychosis, and cannabis use is a known risk factor for psychosis. Previous evidence suggests that AffI may itself be a risk factor for cannabis use. This study aimed to investigate the longitudinal relationship between AffI and cannabis use during adolescence and the development of psychosis in early adulthood. Study design Data from the Avo…
Open article record in new tab ↗Background Excessive marijuana use is associated with greater negative consequences, especially among youth. Identifying factors influencing these outcomes is crucial. While the Big Five personality traits are considered distal risk factors, marijuana motives act as more proximal mechanisms to marijuana use. Objectives This study aimed to examine the mediating role of marijuana motives (Coping, Enhancement, Social…
Open article record in new tab ↗Objectives Cannabis is one of the most widely used psychoactive substances, and many adults meet the criteria for Cannabis Use Disorder (CUD). Prior research on its association with cardiovascular disease (CVD) has yielded mixed results. This study evaluates the relationship between CUD and CVD among ED patients. Methods This retrospective, propensity-matched analysis examined records from 67 US healthcare organiz…
Open article record in new tab ↗Purpose of review This scoping review used a five-stage framework to evaluate empirical studies positing anxiety and depression as mechanisms or moderators in associations between cannabis use and sleep. Applicable peer-reviewed studies were identified in Google Scholar and PubMed using relevant search terms (e.g., cannabis, sleep, depression, anxiety). Recent findings Of the 20 articles included, most examined ca…
Open article record in new tab ↗Introduction Understanding retailer advertising has been identified as critical for developing effective policies to reduce tobacco product use, as these forms of advertising are among the tobacco industry's largest expenditures. Online retailer marketing has grown rapidly, and in this study, we sought to describe the marketing practices of these retailers. Methods Between March and July 2022, we conducted keyword…
Open article record in new tab ↗This paper focuses on school climate indicators, which have been previously linked with aspects of students' well-being and school-related success, to explore how they relate to alcohol and cannabis use. We used machine learning (ML) approaches and leveraged data from a diverse sample of 69,513 students (45.4% White, 23.9% Black, 8.9% Latine) across 111 middle and high schools, with 12% (n = 7783) reporting cannab…
Open article record in new tab ↗Aims To estimate the prevalence of prenatal cannabis use in Michigan, USA, using self-reports and urine toxicology and to examine factors associated with use. Design Observational study using data from the Michigan Archive for Research on Child Health (MARCH) cohort, part of the National Institutes of Health's Environmental influences on Child Health Outcomes (ECHO) program. It is a prospective statewide pregnancy…
Rationale Between periods of use, chronic cannabis consumers may display residual effects on selective cognitive functions, particularly memory and attention. Whether there are comparable deficits in real-world behaviors, such as driving, has not been thoroughly examined. Objectives The current study explored the association between driving simulator performance, cannabis use history, and demographic factors after…
BACKGROUND: Colorado was the first state in the United States to legalize recreational cannabis, which provides a unique opportunity to evaluate cannabis urine drug screen (UDS) testing trends in a large healthcare system in response to that policy. This study examined how testing rates and positivity evolved over time and whether testing patterns varied by demographic factors. METHODS: In this retrospective cohor…
Open article record in new tab ↗Background/Objectives: Current literature regarding the efficacy of cannabis to reduce chronic pain intensity is mixed. Despite growing accessibility throughout the U.S., it is still unclear if the naturalistic use of recreational cannabis edible products is associated with decreases in pain intensity on days of use or longitudinally, and if these associations are dependent on the doses of delta-9-tetrahydrocannab…
