The legalization of sports gambling has recently become a major social policy issue in some North American jurisdictions. Unfortunately, there are few guiding principles to help policymakers in their deliberations. This paper presents a synopsis of the main practical and moral arguments for and against sports gambling. The discussion of the consequences of legalizing sports gambling follows a sociological overview that emphasizes the scope, growth, and appeal of the activity. The concluding section examines the future of sports gambling: why legalization appears inevitable, the formats legalized sports gambling may take, and where in North America the enabling legislation is most likely to surface.
