It depends on one persons self control ...its all about yourself .as for me when you are addicted into something..activities or things etc.its always bad for you..especially in gambling when you gets so addicted into in and you can no longer control your self we can say yes a disease..because dicease have diffenrent type...one is past it on to one another and theres a disease that couldnt past it on just like mental disease..
I don't think that being addicted to something is bad at all. Just like what the popular saying that in every rule there is an exception, what if that addiction is very useful and beneficial to you? I know most of the addictions are really bad for one's mental and physical health and it can even break a family but don't generalize it.
So in same capacity we can say gambling a fatal disease that can make someones life ruined. There have been so many people who are totally disrupted in their lives just because of this game. People dont understand that money is the only way to be happy in this era. If you dont have money, poverty will grasp you and all your happiness will be leaving from other side. So dont just make yourself poor.
