I agree and disagree. While short term addicts can usually revert to who they once were, long term addicts will be changed. They will never be the person they were before their addiction. But that doesn’t mean they can’t be a beautiful, loving and lovable person. But their humanity? Over half of all heroin addicts eventually get sober and live productive lives. Anyone who’s spent enough time in 12 step rooms, where they can observe first hand the tremendous amount of time, effort and heart the expend helping their fellow addict.
