Examination of the Legalization and Decriminalization of Marijuana on the DWI System: Phase 1

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

Phase 2 is a project to collect the data based on the recommendations of the panelists. A draft final Phase 2 report is under revision.
