Legacy gambling harms are the negative consequences that last beyond the period when people gamble heavily. This article is a review of types of legacy gambling harms, how long they last, and whether legacy harms are real or simply reflect regrets or remembrances of past harms. At an individual level, legacy gambling harms can be categorised into financial, relationship, emotional/psychological, health, culture, work/study, and criminal/deviance harms. Legacy harms also occur to families and the broader communities. Most legacy harms have a half-life of 4 years. Financial harms have a longer half-life of 5 years. People who experience more legacy harms have lower well-being. Moreover, well-being increases with greater distance in time from the past gambling issue. This suggests that legacy gambling harms have a real impact on well-being.
