This document looks at drug and alcohol use by 340 regions withing the U.S. I've skimmed it and here are a couple if interesting findings:

• Of the 15 regions with the highest rates of illicit drug use, three are in Michigan.

• The region with the highest percentage of people consuming alcohol is Washington D.C.'s wealthiest ward. (politicians?)
