Examination of the Legalization and Decriminalization of Marijuana on the DWI System: Phase 2

This project examines how states’ DWI systems evolve with the legalization and decriminalization of marijuana. 

Phase 2 collects data based on the recommendations of the expert panel from Phase I. A draft final Phase 2 report is under revision.

Phase I consisted of an expert panel meeting. A summary report was written and published in 2017, and GHSA issued a news release to announce its availability.
