Background: Across the nation, growing numbers of individuals are exploring the use of cannabis for medical or
recreational purposes, and the proportion of cannabis-positive drivers involved in fatal crashes increased from 8
percent in 2013 to 17 percent in 2014, raising concerns about the impact of cannabis use on driving. Previous
studies have demonstrated that cannabis use is associated with impaired driving performance, but thus far,
research has primarily focused on the effects of acute intoxication.
