That will never happen. If a person decided to stop gambling because he realized that he already has a gambling addiction and it is progressing he will stay away from gambling and not play even with fake money because such a game is not able to resist addiction and most likely even aggravates the already deplorable situation.
I know a guy who lost a lot of money because of his gambling addiction and now he completely ignores it without even playing cards with his friends.
Those which have never been addicted to anything may feel that such a posture is too extreme but it is precisely what it must be done, the desire to go back to their old ways is too strong for those which were addicted to something, and as such anything that resembles the activity may be more than enough to lead them to that path again, so it makes sense that the person that you know does everything he can to avoid putting himself in a position in which he could fall victim of his addiction again.
