This study will build upon the research team’s existing work with state laws addressing traumatic brain injury (TBI) and sport-related concussions. It will be the first study to evaluate TBI law data using concussion data from a national surveillance system.
Illegal drug use is a persistent problem, prescription drug abuse is on the rise, and there is clinical evidence that drug use reduces driving performance. This study describes trends in characteristics of drivers involved in fatal motor vehicle crashes who test positive for drugs, and finds that the profile of a drugged driver has changed substantially over time. An increasing share of these drivers is now testing positive for prescription drugs, cannabis, and multiple drugs.
