The Science of Cannabis and Driving

This talk will focus on the current state of knowledge about cannabis and driving. Topics will include: what lab and roadside studies tell us about how cannabis use affects driving ability and alters crash risk; how does
cannabis-impaired driving differ from alcohol-impaired driving, and what does this mean for policy, enforcement, prevention, and intervention efforts; what are the most critical gaps in our understanding of cannabis and driving.

Learning Objectives:

  • How acute cannabis impairment affects driving ability – including both epidemiology and laboratory findings
  • What can and cannot be translated from alcohol impaired driving efforts to address cannabis impaired
    driving
