Psychiatrist Doctor Tanveer Ahmed says gambling addiction is about behavioural 'impulse' control, with problem gamblers making up 'almost a third' of total profits.
'I think gambling is much more ubiquitous with online and the internet than it has been, especially in the last five years, so I think there is a bit of a community concern we're taking it out on the pokies,' Dr Ahmed told Sky News host Chris Kenny.
'In my field, gambling's known as a behavioural addiction � so it's not like a substance that causes a physiological change, but it's still about poor impulse control, not being able to regulate rewards, so there is something in this, and I think Perrottet's clearly seen it as a winner.
'We don't actually know how it's going to operate � the argument might be the problem gamblers, still in terms of the revenue, make up almost a third of the total profits, even though they're a tiny portion.'
