Abstract

Guilherme Messas is a Brazilian psychiatrist, founding member of the Brazilian Society for Phenomeno-Structural Psychopathology and author of many peer-reviewed articles in the field of psychopathology. His book entitled 'The Existential Structure of Substance Misuse' is an important and comprehensive phenomenological analysis of psychoactive substance abuse behaviour, considering a field still partially explored by clinical and psychopathological research. The contents provided by the author in this work are not only of great theoretical relevance, but also of clinical utility in the rehabilitation of these patients. It would be important to deepen the field of phenomenological research in addictions, exploring the contents proposed with the aim of providing tools and knowledge that would be of concrete help in the treatment pathway of substance abuse.
