I think the best thing that you could ever do, when trying to help those afflicted with addiction, is to be relatable a/o understandable. You could learn what addicts go through by attending some NA/AA meetings as well as SMART meetings. Also, visit a site called SoberNation...they have really good articles that are very in depth pertaining to the Psychology of addiction. Are you going for your Masters in Psychology? I am still an Undergraduate, also pursuing a degree in Psychology. I am also a recovering addict.
