There have been recent and substantial increases in access to legal gambling in the US and abroad. My research looks at different ways to identify impacts on public health that this increase might entail. Using data from digital media, surveys, and administrative sources, I use longitudinal quasi-experimental techniques to track changes across important changes in gambling policy and provision. Impacts include changes in participation in online mutual support forums, alcohol-involved crashes, and prevalence of Gambling Disorder symptoms. I am also interested in the disproportionate impacts that gambling can have on those over the age of 65, those experiencing difficulties with mental health, and low income communities.
