It is indeed challenging to be a responsible gambler; only a small fraction of those who engage in gambling can do so responsibly.
Being responsible is not a decision we can make because we want to and then be Irresponsible in other aspects of life, if we are responsible we will be responsible in everything, we may get Carried away by emotions in a casino , but the Responsible person will not lose a lot of money because they know they must maintain themselves and cannot give in, those who do run the risk of getting into trouble and obviously falling into addiction.
