This is very clear and logical point that is major concern for public health experts. Yes constant rise of new casinos and gambling platforms pushed by competition and creates ripple effect. More gambling options lead to more aggressive advertising which makes gambling seem normal and harmless. This easier access and constant publicity can lead to more people trying it increasing risk of gambling addiction. And it is logical to think that fewer casinos might mean less addiction but real issue is not just number of options but how well they are regulated to protect players.
