Again it's not her, she's just a face of the vehicle, one with no positive quality, drugs can at least be social. (yes you can earn a bit of money, you could also earn it by being productive)
Money that is inconceivably removed from the lowest portions of society is pretty much permanently lost to them, making it more difficult, if not impossible for that area to ever improve without gentrification or improved education. If these folks didn't have this convenient addictive vehicle to spend what little they might have (possibly getting into gross amounts of debt, possibly to criminal's willing to make life miserable and ensure a violent cycle), they might indeed just spend it on a different one (fair argument), but there's the glorious chance they spend it on something a tad more useful to them or others. Now if loansharks and the like fine it relatively easy to slither around such folks, in an increasingly incohesive society that we seem to have nowadays over relatively incoherent arguments about economic/social views, then much more dangerous people can probably do so aswell, we know how easy it is to manipulate people... so this is practically a given future for some of these people.
Though there will always be people who will want to gamble, legally or otherwise, so maybe there is no point in restrictions, if all it would do is secure it in the hands of criminals, but then if that's the case then it's up to the government to provide better futures for them instead, rather than increasingly vapid politically motivated policies that push the truly in need of guidance towards nefarious purpose.
I just believe there are too many depreciative cycles in society at the moment, leading to more anxious and depressing circumstances that could all turn repressed anger into violent ends, it's rather clear from the increased suicide rates and increasingly vapid climate.
