I think there are different level of addiction which we need to know and be aware about. There are less serious addictions which can not have serious effect on gamblers and the way they bets. There are also bad addiction that can make us to keep gambling without thinking about losses and the potential of us losing big from gambling. Losing money in gambling is also the same thing as financial losses and we need to be very aware of how we spend and what we are spending on. People keeps losing money in gambling because they are not focused and want to make money immediately.
I don't think there's any good addictions when it involves gambling, if you're not gambling in a coordinated manner, you would be gambling in a bad way that it wouldn't be good for you. Gambling addiction will destroy your confidence and it can cause you to become indebted because you didn't budget yourself well while gambling. Gambling addiction will not only make you to be losing money but also makes you to lose other things that are important to you. The worst mistake a gambler can make is to allow gambling addiction to take control of him because that'll be the end of his winnings days. You can't be losing and be happy so gambling addiction also destroys your happiness.
