Importance: Little is known about patterns (forms, frequency, and reasons) and factors associated with cannabis use in older veterans (aged ≥65 years). Objective: To examine factors associated with past 30-day cannabis use and cannabis use disorder (CUD) in older veterans. Design, Setting, and Participants: In this cross-sectional study, community-dwelling adults aged 65 to 84 years who used Veterans Health Administration care were interviewed between February 5, 2020, and August 29, 2023. Exposure: Sociodemographic, behavioral, and health-related characteristics. Main Outcomes and Measures: Past 30-day cannabis use (smoking, vaping, dabbing, or edibles) and any CUD (≥2 criteria based on Diagnostic and Statistical Manual of Mental Disorders [Fifth Edition]) were assessed using weighted multivariable logistic regressions. Results: Of the 4503 participants (weighted mean age, 73.3 years [95% CI, 73.0-73.5 years]; 85.4% [95% CI, 83.6%-87.2%] men), 58.2% (95% CI, 55.3%-61.0%) had ever used cannabis, 28.9% (95% CI, 26.0%-31.8%) of whom reported using cannabis for medical reasons, most commonly for pain (56.4%; 95% CI, 50.9%-61.9%), mood or mental health (18.4%; 95% CI, 14.7%-22.1%), and sleep (16.0%; 95% CI, 11.9%-20.0%). More than 1 in 10 reported past 30-day cannabis use (10.3%; 95% CI, 8.9%-11.7%), with 52.4% (95% CI, 45.4%-59.4%) of these using cannabis for 20 days or more; smoking (72.4%; 95% CI, 65.4%-79.3%) and edibles (36.9%; 95% CI, 29.8%-43.9%) were the most common forms...
