In my country, lot of institutions running out-of-home-campaigns against gambling-addiction etc.; so yes, if public institutions are doing this then there is some evidence there
I don't doubt that the programs are helpful, but how does that equate to evidence?
Creating a campaign doesn't prove in anyway the specific problems caused by gambling, especially at the societal level. It only shows that there is a group willing to fund programs against gambling addictions.
In no way am I questioning the intent or value of such programs, I hope it doesn't read that way. It just isn't necessarily relevant with regards to evidence.
