I doubt that you can stop gambling when you are addicted since it’s very hard to notice the symptoms due to the addictive nature of gambling. The only way for a compulsive gambler to stop is if someone help him to change or he doesn’t have any money to gamble.
I think to come out of addiction is based on certain circumstances which I agree that if someone doesn't have money to gamble again then that can force him to reduce playing and probably stop totally. But if you try to stop the person where he is still having money to play, the person will still look for ways to play because he already have passion for playing. Gambling addiction is like a passion and only very few things can stop someone out from there passion like if the person is physically not dispose to it anymore.
