‘Codependence: Coping with Addiction, Sadism and Abuse (Essays on Law, Policy and Psychiatry, Vol. 1, 2018)’ is based on a white paper I drafted years ago for a drug rehabilitation center in the United States. The study is basically divided in three parts, dealing with different manifestations of parent-child codependence and the resulting lacking autonomy and self-reliance of the later adolescent and young adult, who, as a result of his early entanglement with a parent gets into a negative growth spiral by a rather queer sexual development (sadism), and dependency patterns in all spheres of life.
