The purpose of this study was to evaluate the level of gambling participation linked to an increased risk of future gambling-related harm. The study used data from the Alberta Gambling Research Institute’s (AGRI) National Project (ANP) online panel survey. Data from Canadian adults were included in the analysis if the respondents (1) completed both the baseline and follow-up surveys and (2) reported gambling participation at both time points. A total of 4,562 people met the inclusion criteria. Overall, the researchers found lower-risk limits similar to the published Lower-Risk Gambling Guidelines (LRGGs). The lower-risk limits found in this study suggest that people should participate in no more than two gambling types and no more than once a week. But the researchers found higher limits for percent of household income spent on gambling between 3.5 and 6.4%, depending on the type of harm. The current LRGGs suggest no more than 1% of household income to be spent on gambling.
