Sorry, not cash cash, I misspoke - I mean a direct deposit into their bank which they can withdraw as cash to spend at smaller shops, opportunity shops, etc.

That will be taken away - the 20% they're allowed they can withdraw, everything else is restricted to be spent at nominated shops. And even though supermarkets are nominated, the cigarettes and alcohol they sell is off-limits. Unless they have the 20% as cash, but they may also need that for new tires, or an electrician, or a birthday present.

Basically you spend on what the government allows - it's touted as reducing addictions, but the addicted are like that because they're usually either lower educated, have less opportunities, suffering mental issues or just want to relax - and that's generally caused by useless governments dropping the ball and scammers taking over the system.
