Some people always get this wrong, not everything is relating to a spiritual issue especially gambling, it's more relating to a mental issue than something spiritual for instance you shouldn't be referring an addicted gambler to the church or spiritual home for prayers, rather such cases should be handled by a mental health practitioner, psychologist or the rightful professionals to handle the situation, your spiritual leader or teacher is just a religious leader meant to handle spiritual cases and not the right one to handle such cases, I don't know about other societies but I've seen people in my region make such errors and it needs to be addressed.
Yeah overtime gambling addictions has led to a lot of misfortune which it has been labeled with different sort of names including being a spiritual entity, and most times when I hear it I laugh over it, it's same thing as being a smoker an addicted one at that and from the start we all know it's develops gradually till the person is unable to stop such habits and then they are stuck, so what will you call that. It's addiction nothing else there's no spiritual attachment of any sort so the person don't need any spiritual prayers or any of that.
