The review examines the place of buying addiction in the classification of non-chemical addictions and other mental disorders, and risk factors for its occurrence. The data on the epidemiology of dependence (from 1% to 10% of the population in developed countries) is observed. The characteristics of neurobiology, clinical manifestations and features of addiction comorbidity are described. Modern approaches to therapy and correction are analyzed. It is concluded that buying addiction, of course, refers to the addictive disorders because of the similarity of their neurobiology, clinical manifestations, comorbidity, and approaches to therapy. Further studies should help to define its place in the classification of mental and behavioral disorders, as well as in the development of adequate and reasonable treatment approaches.
