Safer gambling messages are one public health strategy used to reduce gambling-related harm. There is not much research on safer gambling messaging for race and sports betting. This review summarizes research on gambling and other public health domains (alcohol and tobacco messaging). Based on their review, the authors discuss five potential areas for improving messages for race and sports betting: (1) teaching safer gambling practices; (2) correcting gambling misperceptions; (3) boosting conscious decision making; (4) norm-based messages; and (5) emotional messages. This review is useful for policy makers and researchers concerned with designing safer gambling messages for race and sports betting.
