That's a flawed mindset, and I don't think gambling addiction is dangerous for adults, as long as they can control their finances and emotions, so there won't be any negative consequences.
It's important to remember that gambling is simply a game for fun, not for money. If that's ingrained in the mind, a person won't do everything just to win and expect money from gambling. Financial and emotional control can be achieved if we realize that it's just entertainment. This only applies to adults with the right mindset, and I believe even that percentage of such individuals is small.
I couldn't fully agree with you. Because you say that those who are adults will have no problem if they gambling. In this case I can tell some of my real life events. There is a man in my clan who is addicted to gamble and currently he is 45 to 50 years (approximately). I advised him to get out of my family many times but he could never get out of it. He even has two daughters, never worry about them. What is in the future of her daughter child and they have to meet the needs properly. Moreover, he was given a lot of money, so that he could move well later. But he was very addicted to gambling, and he lost all the money by gambling. And he has no accommodation now, then he is constantly gambling. Yes, it is true that he may have a mental problem but even if an adult does not think about himself, his family and child should think about. So that they cannot be harassed to any kind.
Moreover, I think if a person is addicted to gambling. Then it is very difficult for him to control emotions and have the right mentality. And at that time does not work with the right thoughts of the gamblers in gambling. And I want to say that whether adult or child, everyone should refrain from gambling. Be it fun or make money.
