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.

An increasing share of these drivers is now testing positive for prescription drugs, cannabis, and multiple drugs.

This study finds that children in counties with unified family courts experienced shorter foster care spells and higher rates of reunification with parents or primary caregivers. Shorter foster care spells translated into improved school performance measured by end-of-grade reading and math test scores. Adult drug treatment courts were associated with lower probability of reunification with parents/primary caregivers.
