ADAI and Policy Initiatives

ADAI researchers and staff routinely respond to requests from policymakers and community partners to integrate subject matter expertise into policy development. This work can involve presenting at educational hearings, preparing policy and evidence briefs, one-on-one educational conversations with policy makers, and delivering testimony to legislators.
In these settings, ADAI experts share information about emerging issues, provide scientific evidence to guide health promotion and treatment strategies, and offer specialized knowledge on cannabis, opioids, stimulants, alcohol, and other substances.
Through these efforts, ADAI helps shape policies that advance public health and address real-world challenges.
Learn more about some of our policy work through the resources below. (Note: As state employees we follow all rules related to reporting any lobbying activities and coordinate policy related efforts with relevant UW government relations staff.)
