gambling addiction is not a severe mental illness that must be entered into a psychiatric facility, the best way to cure gambling addicts is to do hypnotherapy. I have personally visited hypnotherapy to reduce my addiction to smoking, and there I saw many patients who have other illnesses (phobias, game addiction, hypersexual, and others) that are being treated or are almost cured.
I think hypnotherapy can solve the addicting problem because that method is working in the subconscious mind, so it will give a command to our mind, body, and soul that gambling is not good for our life. Maybe people who have an addict to gambling can try this method, and they need to trust the psychiatric that they will help that person to solve the problem. I think that it is worth to try if they really want to have a good mind, and they want to cure addicted to gambling.
