This work explores drug users experiences in Curitibas metropolitan area, in the state of Paraná under subjects own perspective activating therapeutic interventions. Subjects were identified from an ethnography of some institutions involved in the drug users treatment, such as the church of Santo Daime Céu da Nova Vida, the therapeutic community Água da Vida and an Anonymous Alcoholics group. Along with the personal histories, I have realized that the narrated experiences assumed a biographical tone. From these indications, I have tried to comprehend what bounded these specific histories, their emergency possibilities and the experiences that were the studys object. I have then realized that subjects places involved a series of characteristics, representations and socialities that set in course the projection of a chemical dependant identity and through it, more or less successfully, the internalization of a habitus. As a result of this process I have observed the production of subjects, defining the way they are in the world, situated and build through internal shifts in the domain of what can be called a drug dispositive.
