Problem
Leo, a 30-year-old male, is a regular customer at your pharmacy and has always been very polite. He seemed a bit down lately and when you asked him, he told you that he is actually an illicit drug user. He started using 'drugs' a few years ago when all his mates used it. Now he is thinking about quitting. He tried to go 'cold turkey' a few times but it hasn't been successful. You tell him that you understand and recommend him to speak to his doctor about the Opiate Replacement Therapy. Explain to him FOUR potential benefits of the Opiate Replacement Therapy.
