Addiction is a special way of life associated with the search for an “ideal” reality. With the help of addiction, a person escapes from the discomfort of reality. But, once found, the new artificial reality destroys health and life. Based on the way a person avoids his own life, chemical (pharmacological) and substance dependencies are distinguished, in which special behavioral options are used. This book describes substance dependencies - the leading problems of modern man. Both well-known forms (gambling addiction, food addiction, computer addiction) and less familiar but common conditions (sexual addiction, shopping addiction, TV addiction, etc.) are considered. 14 types of dependencies are described, each of which is devoted to a separate section. You will be able to familiarize yourself with the mechanism of occurrence and signs of addiction, assess their presence in yourself and other people in a special test. Each section contains special author’s training on preventing or overcoming addiction. The book is accessible to readers of any level - from psychotherapists, narcologists, psychologists, to all readers interested in their mental freedom and health.
