sorry in advance, maybe I have a slightly different view from most of the members here.

In my opinion, in the treatment of an addicted gambler, there are indeed several factors that must be addressed. and if it is indeed serious, it is indeed advisable to involve treatment by an expert, because this means it is related to addiction, such as drug addiction and others.

But, this is not the only thing that is needed in strengthening the mind and also resolving addiction problems in gambling. But indeed spiritual strengthening is indeed involved in the treatment of addiction by experts. so there must be continuity between:
- Mental strengthening
- Behavioral strengthening
- Spiritual strengthening
- Medications
- Mediation and Self-help groups
- Environmental judge and influence

And maybe there are several other factors.
but, indeed spirituality is one of the components in the healing process of gambling addiction (remember, one, not the only one). And this is in several journals and scientific articles.
