Formative Research and Resources to Prevent Cannabis Impaired Driving Among Teens and Young Adults

Driving under the influence of cannabis is illegal in the United States and remains a significant public health problem, particularly for young drivers. Young cannabis users may perceive cannabis as a safe alternative to drinking and driving. Among high school students, cannabis impaired driving may be more prevalent than alcohol impaired driving (CDC, 2018). Almost half of teen drivers who use marijuana reported driving after using marijuana (Li et al., 2020). Despite the magnitude of this problem, there are still many gaps in our understanding of young adults’ knowledge, attitudes, and beliefs; the contexts in which they make the decision to drive while impaired, and what interventions are promising for promoting safer driving behaviors. Research suggests that interventions focused on parental monitoring, knowledge, and support are protective against risky behaviors, including driving or riding under the influence (Kaigang, 2014; Botzet, 2018). Formative research that addresses adolescent and young adult social norms, attitudes, knowledge, and perceptions are, therefore, needed to help prevent cannabis impaired driving. Similarly, examining the body of work describing interventions that involve parents or other caregivers and the efficacy of them is also critical. The objectives of this research are to (1) design and implement formative research to identify teen social norms, attitudes, knowledge, and perceptions related to cannabis and driving, and evidence-based approaches and models to support parents and caregivers of teens; and (2) develop educational resources that support parents and caregivers in talking with teens about cannabis impaired driving. The project will develop educational resources to support parents and caregivers in talking with teens about cannabis impaired driving and impaired driving laws. Additionally, the educational products will serve as a resource for State Highway Safety Offices and/or other organizations working with teens, parents, and caregivers to prevent cannabis impaired driving.
