Reccomended by a physician friend of mine, and read from the perspective of someone whose gone through the lived experience of active addiciton and recovery as well. This is the most effective piece of literature i have consumed elucidating the trauma informed approach to addiction medicine, understanding and recovery. That is the essence of the book- trauma informed approach to addiction science and understanding. Theres lots of technical and research based writing and commentary and is written from a nearly clinical perspective, though it does delve into the psychospiritual implications of addiction and the emotional and social aspects in narrative form of others stories and firsthand accounts. All over has a strong message, is factual and evidence based and yet toned with spirituality and nearly transcendental commentary.
