Purpose: Although cocaine is one of the more commonly found illicit drugs in injured drivers, its role in collision causation is unclear. This study examines the relationship between self-reported collision involvement and cocaine use among Ontario adult drivers.
Method: Data are based on the CAMH Monitor, an ongoing general population survey of Ontario adults. Five years of data (2002, 2003, 2004, 2006, 2008) were merged for this study (N=8,107) due to survey item availability. Logistic regression analyses examined self-reported collision involvement in the last 12 months by past year use of cocaine, while controlling for age, gender, income, alcohol consumption, and drinking driving factors.
Results: The prevalence of self-reported collision involvement within the past year was 18.8% among those who used cocaine in the past year compared to 7.4% of non-users. Preliminary analyses, controlling for demographic and alcohol-related factors found cocaine use is a significant risk factor for collision involvement (OR=2.25).
Conclusions: This study suggests that cocaine use is associated with increased risk of collision involvement. Additional work to confirm these observations, and to identify the conditions under which those increases in risk can be modified, is needed. Analyses of survey data can play a valuable role in this work.
