Reconstructing Subjectivities: Dynamics of a Therapeutic Community in the Federal District is a book that focuses its gaze on the work of a therapeutic community aimed at treating young drug addicts. It seeks to observe the relationships that are formed in this space and the objective and subjective implications for the boys who find themselves there. From the concepts of agency and power, the intention is to understand how the processes of subjectivation and constitution of subjects occur around the problem of drug use. Therapeutic communities can be seen as a form of therapeutic agency that seeks to reconstitute subjects and life projects in relation to the phenomenon of drug addiction. This is a study that provokes reflection on the limits and possibilities of this alternative intervention to drug abuse, contributing to future studies on the subject.
