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.
I agree with you and this passion grows bigger and bigger with the passing of time,it is different from other passions which after 1-2 years they start to fade away from the level that you had for them in the beginning and this is a big problem.If the person is run by his passions and not him running the passions this is much more emphasized in the gambler which can really fall prey to addiction very easily.In order to stop having not money is not enough as he will stop only temporarily while to quit for good you need professional help and a strong inner desire to quit,there is no other remedy to this.
Most gambling addicts play games without being able to control themselves so that gamblers are controlled by the games they play, and in such situations they are easily trapped in addiction because they will continue to play in a state of passion and emotion. And that keeps them playing until the money runs out, which may only be temporary. Because in the end they will play again even though they only have a little money and even though they don't have any money, they will look for ways to get money so they can gamble.
Actually, addicts like that don't recover quickly, but eventually recover by themselves. And either after losing everything or they realize it after going through a lot of hardship and even losing some of their valuables and there are also people close to them, because they think it's too much. And I myself often encounter gamblers like that, including my own friends, and most of them are involved in slot games.
