It helps, families have a special bond not only on blood but also on their feelings so if there are people who can help the gambling addict it should be the family, the reputation of the family is always at stake when one of its members is astray so members of the family will help together to get the member of the family at the right path.

The best way to cure addiction is only through rehabilitation, but rehabilitation will not succeed if the family does not support the member in the process of healing.
