When it becomes difficult for someone is addicted to gambling to quit. I think its not just about quitting gambling he has to do, if he as any other thing he is addicted to he should first quit on those ones because quitting those ones might make him lose interest automatically in gambling.
It was an influence. But wait, not every addiction is completely bad, aside from those you have mentioned, OP. However, being addicted to gambling is something that we have to worry about because this will not just end our wonderful life and living, as it will certainly paralyzes our financial stability if it becomes worse. Some say, "Let's enjoy life." Well, there is nothing enjoyable if we carefully manage our lives. Being addicted to anything is already not a normal condition, especially if that could cause major problems financially.
