A gambling addict always think he would make it through gambling despite his or her loses, the idea is that one day will be their day. so to help such people as a member I think is to draw them closer show them some love so they will have interest to what ever ought to say to them. let them know that it's not as they think, give them a constructive reason why they have to leave it because gambling is a thing of 50/50 chance. many people are in mess today because of gambling
Gambling addiction is just a very bad thing, and anyone who is addicted needs their family and friends support more than ever because it's not easy for them to pull out of it alone. Those who are close to them are the ones who can talk them out of it, stay close to them, and distract them from gambling.
But another thing about some gambling addicts that makes it difficult to help them is that most of them don't even agree to the fact that they are addicted. Even when you point it out to them, they still argue that they are still on their normal gambling behaviour, which makes it harder for such people to learn and be corrected.
