I think that the Government should ban the sale of all gambling products, e.g lottery tickets and scratch cards, in general shops, such as supermarkets, unless via a dedicated till that have restrictions, are gambling registered, and where self-exclusions apply.

I think people being able to buy gambling products alongside their regular shopping presents a danger to gambling addicts. People may have self-exclusions but then can buy lottery tickets and scratchcards in shops, and use their credit card.
