Yes, that is true. In fact such cases are increasing from time to time. I personally know some people in my neighbor who are addicted gambler and now they have started illegal activities to collect money for playing gambling, I think that we need to educate people to avoid playing gambling or at least should play up to their limits. Where they can afford to lose a limited amount of money, which may not affect their social life.
Because they are lack of self-discipline, gambling isn't bad if you know how to handle this. Having self-limitation is very important and you must be contented of what you have earned or loss as what you have set capital. However, it makes worst if you can ride your emotion and greed will be on the top, that is useless.
