With the global expansion of sports gambling over the past decade, there has also been an expansion in concerns about the potential deleterious effects of such gambling. Though the majority of sports gambling individuals report no negative effects associated with their gambling, there is increasing evidence that, for some, sports gambling is a risky behavior with many potential negative associations. One particular domain in which these negative associations may be particularly concerning is with regards to substance use. People who engage in sports gambling watch more sporting events than people who do not and they often do so with other people and in locations where alcohol is sold (i.e., sports bars). Sports viewership is associated with greater alcohol consumption, particularly among young adults in collegiate settings. Beyond college settings, televised sporting events (e.g., the Superbowl, in the U.S.; the FIFA World Cup, internationally) are linked to greater alcohol consumption and alcohol related harms. Given the above, the present symposium is primarily concerned with understanding the links between sports gambling and substance use. Mr. Alex Connolly will present data related to overall associations between sports gambling and substance use and the frequency with which people report drinking and gambling at the same time. Dr. Andrew Kim will present data from ecological momentary awareness studies that details the momentary associations between substance use and risky gambling behavior. Finally, Dr. Joshua Grubbs will report data related to the longitudinal associations between sports gambling engagement and drinking related problems over a two-year time span. Collectively, these diverse data points and methodological approaches will shed light on how sports gambling seems uniquely related to substance use and will discuss potential implications for preventing harm associated with each behavior. Learning Objectives: At the end of this presentation, audience members will be able to: 1) List key differences between how sports gambling individuals and gambling individuals who do not gamble on sports use alcohol alongside of their gambling. 2) Explain how alcohol use is linked to particularly risky sports gambling behaviors. 3) Describe how sports gambling corresponds to alcohol related problems over time.
