Marijuana Research Report, 2017 – 2019


ADAI’s new Marijuana Research Report describes our many research studies, collaborations, and dissemination efforts conducted during the 2017-2019 biennium with support from the Washington State Dedicated Marijuana Fund.

During this period the Institute supported 8 pilot research studies on marijuana by scientists throughout the UW, bringing the total to 15 small grants funded since 2015, and 5 intramural projects within ADAI. Findings from these grants continue to lead to full projects with outside funding, and numerous publications and presentations. In collaboration with colleagues at WSU we hosted the 3rd Marijuana Research Symposium, with a keynote address by Washington Attorney General Bob Ferguson. ADAI also conducted scientific literature reviews in order to develop 13 research-based factsheets and policy briefs that can be found at and

Looking forward, ADAI will continue to support pilot research studies on marijuana. We’re starting to plan the 4th Symposium on Marijuana Research for Spring 2020, where we will again share marijuana research with policy makers, healthcare providers, and the research community.

Our scientists and information specialists bring a wealth of expertise to aid policy makers, clinicians, and the public to better understand and respond to the impacts of legal marijuana in Washington. We’re proud to present this report of our most recent accomplishments in this important area.
