The issue of gambling addicts is large, it's positive to some and negative to others, it's the second set that is feeling the brunt and needs help. I will never support anything that is affecting anyone negatively and the person still doing it, people should always observe themselves and try to shun or reduce anything that seems to retard them. In gambling, desperation is the main cause of addiction, they would want to win by all means, and the more they lose, the more they either believe that there is hope to win or are emotional to try to recover back their losses.
Either way, when you know that you are betting and increasing risk and still losing, you might want to take a break. And if you know you can't control this, you should share it with people or get extra help as you might have been so addicted to the extent that you'd crossed the red line.
Addiction, be it gambling or any other, can't give positive results. If by "positive results" you mean winning some money, then it's even worse. A gambling addict winning a big amount only becomes more addicted to gambling. It's horrible. No money will help you to live happily then. Well, if the money were spent on expensive therapy, it could help. But other than that it's a tragedy.
Can someone add additional activities to reduce their addiction or gambling habits, maybe it will be useful and help addicts reduce their addiction to gambling, maybe it's the right thing to do, and come back to those who do it have the desire to get rid of it addicted or not, if he doesn't have the determination inside it is also very difficult to get rid of his gambling habit, even though we advise him they will ignore our words, so in my opinion it is better to advise people who want to be advised by others, then it will be useful for him we alone..
