Abstract
Marijuana legalization is a recent change in some U.S. states and continues to be controversial. Colorado was one of the first states to legalize medical marijuana and, later, recreational marijuana in a voter-approved referendum. Since the legalization of medical marijuana, marijuana-related traffic deaths in Colorado have increased, and more drivers have tested positive for marijuana. Research on the state-level impact of the change in legislation was needed. The purpose of this quantitative study was to examine the relationship between traffic accidents involving cannabinoids in Colorado before and after marijuana legalization. Rational choice theory provided the framework for this study, along with perceptual deterrence theory. Data on crash rates pre- and post-legalization were obtained from the National Highway Traffic Safety Administration Fatality Reporting System and analyzed. The results of the study indicate that recreational marijuana legalization contributed to an increase in traffic fatalities. These findings indicated the need for additional funding for traffic safety, marijuana use and its impact, and traffic fatality prevention. The study findings may be useful for positive social change by officials, advocates, and other stakeholders in other U.S. states who are weighing whether to legalize marijuana for recreational use, as well as a need for governmental programs to address traffic fatalities due to marijuana use.
