Currie et al.'s study draws upon data from large prospective studies and advances previous research on this topic. They develop guidelines using general participation measures (times participated per month, monthly gambling expenditure, percentage of income spent on gambling), but caution against premature application.
Currie et al. conclude that low-risk gambling limits can be developed. The challenges, however, are underestimated and may be unsurmountable. This in no way negates the value of increasing research on the largely neglected topic of linkages between gambling participation and gambling-related harm.
