The widespread legalization of cannabis has increased its use. This meta-analysis evaluates the effects of preoperative cannabis usage on TKA and THA outcomes and complications. Methods This review follows CRD Guidance for Undertaking Reviews in Healthcare and PRISMA 2020 guidelines. On October 12, 2023, we extensively searched MEDLINE (PubMed), Scopus, Cochrane Central Register of Controlled Trials, and Web of Science. There were no time, place, or language restrictions. We also examined the references...

Highlights • Medical Marijuana use is correlated with control of pain, anxiety, and poor appetite in ALS patients. • Medical Marijuana use is not correlated with control of insomnia or spasticity in ALS patients. • Medical Marijuana use is not correlated with maintenance of Body Mass Index in ALS patients. Abstract Following legalization, Medical Marijuana (MM), has been used to treat the symptoms of Amyotrophic Lateral Sclerosis (ALS), yet data regarding Medical Marijuana's efficacy is lacking. Thus, we conducted a retrospective cohort study to assess Medical Marijuana's impact on ALS symptoms and progression. We reviewed the...

Abstract Given diversified cannabis products, we examined associations between cannabis consumption methods and cannabis risk perception of smoking cannabis 1–2 times a week. Using the 2022 U.S. National Survey on Drug Use and Health data (N = 12,796 past-year adult cannabis users; M = 6127 and F = 6669), we used multinomial and binary logistic regression models. Smoking was the most prevalent method, followed by eating/drinking, vaping, and dabbing. One-half of cannabis users reported no perceived risk of smoking cannabis 1–2 times a week, 37.5% perceived slight risk, 9.2% moderate risk, and 2.9% great risk. Those with moderate or great risk perception had a...

This study aims to determine the impact of nonmedical whole plant cannabis use 3 hours prior to sleep and measured cannabis metabolites on polysomnogram measures. Methods: This is a cross-sectional study of 177 healthy adults who provided detailed cannabis use history, underwent a 1-night home sleep test and had measurement of 11 plasma and urinary cannabinoids, quantified using mass spectroscopy, the morning after the home sleep test. Multivariable models were used to assess the relationship...

We examine relationships between sociodemographic characteristics, cannabis use modality, risky cannabis use, and source of cannabis. Method: Analyzing a representative sample (unweighted n = 8,089) of U.S. adults living in medical cannabis–permitting states with past-year cannabis use from the 2021 National Survey on Drug Use and Health, we determined source of last cannabis used. Outcome groups were purchased from a dispensary, purchased from another source, or nonpurchased source. Incorporating the complex survey design, descriptive statistics and adjusted multinomial logistic regressions evaluated associations between sociodemographic, individual cannabis...

Key Points Question  Is prenatal cannabis use, particularly when used to reportedly cope with mood and stress, associated with changes in depression and stress across trimesters? Findings  In this cohort study of 504 patients, cannabis use during pregnancy was not associated with changes in depression and stress through pregnancy, even among those using cannabis to cope with mental health problems. Meaning  These findings suggest that cannabis use during pregnancy does not accelerate the rate of change in depression or stress, even when individuals report symptom relief as their motive for using the drug. Abstract Importance  Cannabis use among pregnant individuals has increased. Depression and stress are frequently reported...

Abstract Introduction: Subjective improvement in gastrointestinal (GI) symptoms was assessed among patients using medical marijuana (MMJ). Methods: Participants completed surveys at 0 days, 30 days, 6 months, and 12 months with questions about the severity of their GI symptoms on a scale from 1 (mild) to 3 (severe). Results: In each survey, participants reported a significant decrease in GI symptom severity when using MMJ versus when not using MMJ (p < 0.05). The most common self-reported side effects from using MMJ were increased appetite (12–21.4%), fatigue (6–16.7%), anxiety (4–11.9%), cough (4–11.9%), headache (6–7.9%), and dry mouth (4–7.1%). Conclusion: In patients with chronic GI symptoms, MMJ may provide persistent symptom severity improvement. Limited...

Abstract Background Rates of cannabis use disorder (CUD) have increased disproportionately among Veterans Administration (VA) patients with psychiatric disorders compared to patients with no disorder. However, VA patient samples are not representative of all U.S. adults, so results on disproportionate increases in CUD prevalence could have been biased. To address this concern, we investigated whether disproportionate increases in the prevalence of cannabis outcomes among those with psychiatric disorders would replicate in nationally representative samples of U.S. adults. Methods Data came from two national surveys conducted in 2001-2002 (n = 43,093) and 2012-2013 (n = 36,309). Outcomes were any past-year non-medical...

Neuroscientific theories of addiction postulate that dependence is underscored by neuroadaptations, but do not account for the contribution of distinct sexes. Further, there is little evidence for sex differences in the neurobiology of cannabis dependence as most neuroimaging studies have been conducted in largely male samples in which cannabis dependence, as opposed to use, is often not ascertained. Methods: We examined subregional hippocampus and amygdala volumetry in a sample of 206 people recruited from the ENIGMA Addiction Working Group. They included 59...

Highlights • Pre-legalization, 19 % of SUD admissions were CUD, compared to 9 % post-legalization. • Adult use legalization was associated with a decrease in CUD treatment admissions. • Differences existed in legalization's associations on different demographic groups. Abstract Introduction Many nations and jurisdictions have legalized non-medical adult use of cannabis, or are considering doing so. This paper contributes to knowledge of adult use legalization's associations with cannabis use disorder (CUD) treatment utilization. Methods This study collected data from a dataset of all publicly funded substance use disorder treatment delivered in California from 2010 to 2021 (1,460,066 episodes). A logistic regression model estimates adult use legalization's...
