Risk and Protective Factors for Driving Under the Influence of Alcohol, Marijuana, and Both Substances in a Population-Based Sample of High School Students

Using results from the 2017 Nevada Youth Risk Behavior Survey, this research aims to understand factors associated with driving under the influence of alcohol (DUIA), marijuana (DUIM), and both alcohol and marijuana (DUIB) among students who reported they drove and used alcohol and/or marijuana recently. DUIM was the most prevalent behavior (16.4%), followed by DUIB (9.3%) and DUIA (4.9%). Weighted multinomial logistic regression analysis showed more risk and protective factors were associated with DUIB than DUIM and DUIA. To decrease motor vehicle crashes among adolescents, interventions should address modifiable factors for driving under the influence of both alcohol and marijuana.
