Understanding the Cultural Influences related to Driving After Cannabis: The Center for Health and Safety Culture completed a research project with the Transportation Pooled Fund on Traffic Safety Culture. The purpose of this research project was to understand which specific aspects of traffic safety culture predict the decision to drive under the influence of cannabis (DUIC). As more states decriminalize and legalize medical and recreational use of cannabis (marijuana), traffic safety leaders and public health advocates have growing concerns about DUIC. The results of this project help distinguish differences in culture between users and non-users of cannabis regarding traffic safety as well as provide recommendations for next steps.
