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~
Agree. Since addiction is mental issue, it should be handed by psychologist or mental health expert. Visiting spiritual home basically is just a supporting matter to strengthen it. If someone only relies on the spiritual factor, it is unlikely to recover the addiction. I'm a bit surprised that there are people who try to recover the addiction by praying only. In any religion, I'm sure everyone is ordered to do proper efforts to succeed in anything. Praying only isn't a proper way to recover addiction case, visiting psychologist or mental health expert is the right way. The God won't give the health if we do it in the wrong way. 
In our society currently things are going on lowest levels which are increasing problems due to domestic issues so they are having mostly consultation with spiritual peoples even mostly are not well organized and have any authority but still they are having good reputation and doing their jobs.
Gambling always creates problems its usual, but handling of these issues always had problem which needed some good work and assist from family and friends as well for me always having better psychology and mental health works much better.
