The Substance Abuse and Mental Health Services Administration (SAMHSA) has many downloadable reports about drug use and health. One that recently caught my eye was about State Estimates of Drunk and Drugged Driving. According to the report, Washington has a relatively low rate of drunk driving that has decreased since 2006 but has a relatively high rate of drugged driving.
Other reports include:
