A new era in gambling gets underway in Massachusetts this week. As of Tuesday January 31 at 10 a.m., sports betting in casinos will be legal in the state. Legal mobile sports gambling is set to start in the state in the following weeks.

Rachel Volberg is a research professor at the UMASS Amherst School of Public Health and Health Sciences, and she is the Principal Investigator on the Massachusetts Gaming Commission’s Social and Economic Impacts of Gambling in Massachusetts (SEIGMA) study.

Volberg spoke with WBUR’s Weekend Edition.

On expectations about the effects of the new law: “We think the impacts are going to be moderate.”
