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.
But most of what happens is a bad influence dude? just imagine gambling makes you an addict, that means every day you're in a gambling circle and the longer you're in the gamble you make is defeat because that's the house system, I think the addict is a disease. unless you can control yourself in gambling the effects may be positive and negative.
If you get addicted that would be the worst experience in gambling, because you will not think wisely and you will always seek gambling.
Remember that in gambling we have less chance to win so it's necessary that we set a limit everytime we play, if we get dictated by our emotion, that would lead us to a big trouble.
