This policy paper outlines GambleAware's call for the UK National Lottery to embed safer gambling messaging into its advertising and products. The National Lottery's brand has a broad reach and there is a high level of trust in the brand. Therefore, the National Lottery could play a substantial role in reducing gambling harms. The UK House of Commons Culture, Media, and Sport Select Committeee recommended adding information about gambling support services in 2022. The paper includes further justification and evidence to support this recommendation.
