Abstract Importance  Cannabis use has increased globally, but its effects on brain function are not fully known, highlighting the need to better determine recent and long-term brain activation outcomes of cannabis use. Objective  To examine the association of lifetime history of heavy cannabis use and recent cannabis use with brain activation across a range of brain functions in a large sample of young adults in the US. Design, Setting, and Participants  This cross-sectional study used data (2017 release) from the Human Connectome Project (collected between August 2012 and 2015). Young adults (aged 22-36 years) with magnetic resonance imaging (MRI), urine toxicology, and cannabis use data were included...

Abstract Background The current study used U.S. young adult data to examine overall and age group-specific historical trends in (a) mean perceived risk and disapproval of cannabis use, and (b) risk/use and disapproval/use associations. Methods Data were collected from 2011 to 2022 from 16,492 respondents aged 19–30 in the national Monitoring the Future panel study. Trends in mean risk and disapproval overall and by age group (19–22, 23–26, 27–30) were modeled. Models regressing any past 30-day cannabis use on risk and disapproval controlled for sex, race/ethnicity, college education, population density, state cannabis policy, region, and year....

ABSTRACT Background This study examined associations between cannabis use among U.S. adults with chronic health conditions in a nationally representative sample. Methods Four cross-sectional waves of data from the BRFSS were used, spanning 2017–2020. Multivariate logistic regression analyses assessed (a) whether number of self-reported chronic health conditions was associated with current cannabis use in the past 30-days, and (b) whether type of major chronic health conditions reported was associated with using cannabis for medical reasons in the past 30-days. Results From 2017 to 2020, the prevalence of past month cannabis use increased among all age groups,...

Abstract Cannabis use among young adults in the U.S. has nearly doubled in recent years, driven by diverse methods of consumption and evolving cannabis legalization. Multi-modal cannabis use among young adults is an emerging public health issue that remains underexplored. This study examines the prevalence, patterns, and predictors of multi-modal cannabis use, defined as the use of two or more administration methods of cannabis use (e.g., smoking, vaping, edibles, dabbing, other forms) in the past month, among U.S. young adults aged 18–34 years. Data from the 2022–2023 Behavioral Risk Factor Surveillance System (BRFSS) across 23 states (n = 7635; weighted n = 7,482,134) show...

Abstract Introduction: Parkinson’s disease (PD) is mainly characterized by motor symptoms including muscle rigidity, resting tremor and bradykinesia. However, the management of the non-motor symptoms represent a relevant clinical challenger in PD. These non-motor symptoms include cognitive and sleep disturbance and there is evidence that cannabinoids may represent alternative and effective treatments for non-motor symptoms of PD. Methods: Therefore, this study addressed the effects of oral treatment with cannabis extract on cognition, insomnia, and daytime sleepiness in six patients with moderate PD. The patients were randomized to receive two different doses of a cannabis extract: THC:CBD 250:28 μg/day (n = 3) or 1000:112 μg/day (n = 3). The assessment of...

Abstract The majority of patients with cannabis use disorder (CUD) regularly take medication. Cannabinoids influence metabolism of some commonly prescribed drugs. However, little is known about the characteristics and frequency of potential cannabis-drug (CDIs) and drug-drug interactions (DDIs) in patients with CUD. Therefore, our study aimed to determine the prevalence and characteristics of drug interactions in patients with CUD during inpatient treatment on an addiction-specific ward over a six-year-period. To this aim, medication charts were analyzed and screened for potential CDIs and DDIs. Herein, the drugs.com classification for potential CDIs and UpToDate Lexicomp program for potential DDIs were utilized. The study cohort consisted of...

Abstract Objective: Rates of chronic pain are higher among rural versus urban individuals and rural individuals experience higher levels of socioeconomic disadvantage, poor or no health insurance coverage, and unmet treatment need. Medical cannabis is legal in Oklahoma. With 40% of Oklahoma’s population living in rural areas, and nearly 17% uninsured, the medical legalization of cannabis may present as an accessible and relatively low-cost alternative treatment, particularly for those with chronic pain. This study investigated differences in cannabis use by rural (vs. urban) status and unmet (vs. met) treatment need among adults with and without chronic pain living in Oklahoma. Method: To be eligible, participants...

Abstract Background Despite advancements in rheumatoid arthritis (RA) treatment, effective pain management remains challenging, with many patients also experiencing insomnia, anxiety, and depression. Cannabis, with its analgesic properties, offers a promising nonopioid alternative. This study evaluated outcomes in hospitalized RA patients using cannabis through the National Inpatient Sample (NIS) database. Methods This retrospective study analyzed NIS data (2016–2021) using ICD-10 codes to identify RA patients. Demographic and clinical characteristics and inpatient outcomes were compared between cannabis users and nonusers. Results RA patients using cannabis (n = 42,415) were younger (mean age 51.8 vs 67.8 years), less likely to...

Abstract Cannabis consumption among aging adults in Canada is increasing. The aims of the study were to examine cannabis consumption patterns before and after non-medical cannabis legalization and assess whether these patterns differ between men and women. Data were analyzed from Canadian respondents in a repeat cross-sectional survey conducted in 2018–2021. Analyses were conducted among adults aged 55–65 (n = 18,177) who had consumed cannabis in the past 12-month (n = 4119). Past 12-month cannabis consumption significantly increased among 55–65-year-olds from 2018 (19.3%) to the first-year post-legalization in 2019 (24.5%; p < .001), but remained stable thereafter (24.3%, and 25.6% in 2020 and 2021). More men reported past...

Acute pain refers to the experience of pain that lasts for only a few hours, whereas chronic pain is the ongoing emergence of pain signals over an extended period. Since ancient times, cannabis has been utilized for medical purposes. This article demonstrates the medicinal importance of cannabinoids through their analgesic and anti-inflammatory activities. Additionally, the mechanisms of cannabinoid-induced analgesia have been interpreted via preclinical investigations in animals. Cannabinoid extracts were formulated into gel and cream at concentrations of 2.5% and 5%. The cannabis cream showed the highest...
