You will found out that every gambling addicted individuals will always loose control of himself and end lacking the perfect direction to how they should live or handle their personal lives, such ends up in hunger because they have no money left to feed themselves with neither do they have any quality source of income that they are serious with and giving them source of income, which means it will do much of harm than good if we are gambling addicted.
That's common in many addictions, but it's specially true in gambling, because you can lose so much money in such a short amount of time.
The thing is that it's an order of magnitude more expensive than any other addictions, because you physically cannot consume/use that much of the drug/addiction in a day, whereas with gambling you can lose all your money in a single day.
