From my perspective, Self-control is the key to getting away from gambling addiction. With self-control, we can know how to gamble and when to stop. And I do not think that all non-addicted gamblers can not control themselves, but all self-controlling gamblers will not be addicted.
Self-control is the key to getting away from all types of gambling. The temptation of gambling comes from within and also there is a social stimulation. But if the person is willing to stop gambling then no one can make them gamble. But if the person wants to gamble no one can stop them from gambling. Hence its totally on the individual's choice whether to gamble or not.
