Jason R. Williams PhD

Jason Williams has worked in the social sciences as an evaluator for many years at the University of Alaska, Anchorage, Casey Family Programs, and as an independent consultant. As a quantitative researcher, he works to inform public policy in areas such as poverty, obesity, child welfare, education, and now at ADAI, drug use epidemiology and intervention.

Dr. Williams designed the Washington State Opioid/Major Drug Interactive Data website, a data visualization resource that offers a series of interactive data charts and maps featuring Washington state data related to overdose deaths, statewide opioid sales, and police evidence testing data for opioids, methamphetamine, and other drugs. He contributes to data collection and leads analysis of community drug checking results.

Dr. Williams contributes to knowledge about cannabis use by analyzing crime lab, survey, sales, and wastewater testing data. He compiled a comparison of survey methodologies that provided insights as to why different surveys produce different estimates of cannabis use. More recently, he contributed data acquisition and analysis to the state Liquor and Cannabis Board’s Disproportionately Impacted Areas project, studies of Washington high school student cannabis use, and exploration of statewide cannabis use, reports of adverse events, recall of cannabis package warning labels, and health beliefs about cannabis.
