Gambling is just like smoking and drinking. Immediately you become addicted, then it has become a problem. That is why is always better for one to control it early before it goes out of hand. Immediately you become addicted, you can only control it by yourself. Although it isn't easy but your self determination is the only key to help you out here.
That is totally not true. A person does not become addicted immediately that one thing. Second thing is there are levels of addictions. Gambling as a hobby can be considered as addiction also. Spending all own and borrowed money, having financial troubles due to making wrong decision in gambling is another form addiction. In fact, I think it is not easy to become addicted to gambling. People are cautious. After losing large amount of money few times, not everyone will be ready to make another deposit and try to win lost money back. Many will leave, get disappointed in gambling and never return.
