Given the increased number of states with cannabis legalization in recent years, updates on driving under the influence (DUI) prevalence and risk factors are needed to inform targeted prevention and intervention efforts aimed at reducing substance-impaired driving.METHODS: We used data from the 2021-2023 U.S. National Survey on Drug Use and Health (N = 139,524 individuals age 18 years and older) for self-reported DUI. After presenting the prevalence of alcohol, cannabis, and other substance use and DUI, we used binary logistic regression models to examine sociodemographic and clinical correlates of DUIA and DUIC, and a multinomial logistic regression model to examine DUIC but no DUIA (DUIC-NA) and both DUIA and DUIC (DUIA&C), compared to DUIA but no DUIC (DUIA-NC).RESULTS: Among those who used alcohol in the past year, 8.6% had DUIA; among those who used cannabis, 20.6% had DUIC. Among those who reported DUIA and/or DUIC, 47.9% had DUIA-NC, 34.0% had DUIC-NA, and 18.1% had DUIA&C. Any severity of alcohol and cannabis use disorder, initiation of substance use during adolescence, mental health problems, risk propensity, self-recognition of substance use problem, and criminal justice involvement were associated with DUIA and DUIC. Age 65+, relative to age 18-25, was also a risk factor for DUIC among those who used cannabis. Compared to DUIA-NC, DUIC-NA was higher among residents of medical cannabis legal states.CONCLUSIONS: Substance use treatment, including mental health screening and treatment, is the most important DUI prevention approach. As cannabis use rises among older adults, prevention strategies must increasingly include this group. States with legalized medical cannabis suggest a need for complementary public safety measures.PMID:41397281 | DOI:10.1080/15389588.2025.2587850
