A lot of people are having gambling problems but I do not think that its bad or something because its logical, I also think that its just a certain time period for people.
Maybe you are not seeing the bad practice of certain people who do have this problem because if you do or if you experience it by yourself you will learn that gambling addiction really needed big attention it ruin a life not only by the players itself but together with his/her love ones too.
Yes, it must be treated as one of the sensitive cases that a person is having. When a person gets himself too much into gambling that is going to make him addicted and it can really ruin his life together with the people behind him. Because he is just going to think about gambling and won't really care on other things and with his family either.
