The article presents the construction of a theoretical-clinical model in psychoanalytic psychopathology about the structural determinants of drug use in psychosis and in schizophrenia. We start from Lacan’s thesis about the effects of adherence to autoerotic jouissance resulting from the rupture with phallic jouissance, which poses the problem concerning the status of this rupture in drug addiction and the role of drug use on the effects of this rupture. Our hypothesis is that the use of drugs follows an attempt at instinctual refusion with catastrophic consequences. We conducted a survey of Freud’s texts that are organized around the drive economy, both in his approach to the use of drugs and in his approach to the etiology of psychosis and the reparative function of delusion. As a result, we obtained the structural indices for the diagnosis of drug use in psychosis..
