Addiction is a medical specialty that focuses on the analysis, diagnosis, and treatment of persons. The Psychosomatic Medicine Conference focuses on this medical specialty. The World Health Organization established a unit for those who suffer from one or more addiction-related disorders. Growing volumes of knowledge, such as the health consequences and covers of misuse, have paved the way for breakthroughs in the field of addiction medicine. These advances in understanding the biological science of reward behavior, together with federal financing, have provided numerous opportunities for research within the field of addiction medicine.
