Gambling can ruin lives as I also have experience even I am living in society where this is openly not allowed but still many addicted and their families suffer with their addiction.
In developing countries no rehab and things for giving them any motivation you have done good job and keeping things on balance which is never been easy.
There are rehabs in my country, we're a developing nation but many don't want to get admitted on it because it costs them money. And thinking about the expense and cost of the rehab, they might just use the money for other important things. But guess what? those very gamblers instead of spending it for the rehab and reasoning for important expenses, they'll just use them back to gambling. That's their motivation and that's why the numbers are expanding and gambling addiction has become prevalent lately after the pandemic.
