Gambling is just for fun not to treat it as your hobby because it can wreck your life.
the only thing make people crazy in gambling is due losing too much
at that moment gambling can turn to a sickness
but generally it's not , gambling is just game of chance.
I don't think gambling is a sickness, who plays it is sick, maybe. It's the same when people blame guns for kills and violence. It's just an inanimated item, it can do nothing by itself. Same happens to gambling, it's just a game to make people happy and to make some profit, surely there are risks and everyone playing this game knows about the risks.
Sick is who play gambling without limits, gambling is just a game of luck...
i think gambling is not same as sick and as mrcash02 said, gambling without limits is really sickness for people that don't know their limits of funds. they only play gambling for the whole day and not doing other activity and its should be a sick person but the gambling itself is not a sickness. i think if we can enjoy when we play gambling and we can get entertain with gambling, then its fine for us to play gambling.
As long as something is been doing without any limitations then that is considered as too much and sickness. And with the definition of mrcash I believe that a gambler who plays without limits are the addicted gamblers who can't able to treat their own sickness. This is the sick that is not able to be treated easily.
