Cannabis Legalization and Driving: Exploring Young Ontarians’ Knowledge, Perceptions and Attitudes

Robert Colonna, The University of Western Ontario

Abstract

The legalization of recreational cannabis may increase driving under the influence of cannabis (DUIC) among youth, a behavior proven to increase the risk of collisions. We conducted a mixed methods study including an online survey (N=426; 53% female) and two focus groups (N=12) exploring young drivers’ knowledge, perceptions, and attitudes towards cannabis use and DUIC. 83.6% (356) of survey’s participants had used cannabis, 69% (296) in the past year. Among past-year users, 47.9% (142) have previously DUIC. Quantitative predictors of future DUIC included: prior DUIC, minor accident risk, dangerousness, perceived enforcement of penalties, punishment avoidance, and moral awareness. Qualitative themes included: Being high is a change in one’s natural state; it is hard to tell if a driver is high; DUIC is convenient, socially acceptable, and safe; legalization makes cannabis more attractive to use; and there is a need for testing, education, and prevention efforts that are relevant to youth.
