Investigating If Changes In Cannabis Expectancies Mediate Driving After Cannabis Use Intervention Outcomes, Sarah Nicole Elder Apr 2022

Investigating If Changes In Cannabis Expectancies Mediate Driving After Cannabis Use Intervention Outcomes, Sarah Nicole Elder

Masters Theses & Specialist Projects

Driving after cannabis use (DACU) has become an increasing public health concern specifically for the states that have legalized cannabis use. In a 2018 survey, 4.7% of U.S. residents reported driving while impaired by cannabis (Azofeifa et al., 2019). Previous research suggests that several skills are impaired following cannabis use, such as increased lane weaving, slowed reaction time, and distorted perceptions about external stimuli. This effect was seen to extend to frequent cannabis users who also demonstrated driving impairments despite heightened cannabis tolerance (Hartman & Huestis, 2013). With the increase in DACU it is crucial to understand the factors that lead to DACU. Several studies have demonstrated that peer norms surrounding DACU, perceptions of consequences, perceptions of dangerousness, and effect expectancies contribute to the decision to engage in DACU (McCarthy et al., 2007; Darke et al., 2004; King et al., 2020). However, it is still unclear which ...
