Gambling addiction can easily be handled through self-control and setting limitations to your gambling activities, once a gambler becomes so addicted to the point that he now builds his life around gambling then you should know that such gamblers will lose money and will be thinking he will recover back through the next bet and that is how casinos generate their revenue.
Casinos will always set their system in a way to suit their house edge and place it an advantage over the gambler, so he just keeps losing to the house every time.
Having self control and setting limitations is easier said than done. There will always be moments when you won't think rationally anymore and will place crazy bets with much higher amounts than you would normally do. Happens to a lot of players, including me. Only thing that helps for me is keeping the balance very low.
