This paper presents the results of a scientific study that focused on the consequences of psychic reorganizations induced by pregnancy among drug addicts. Based on data from interviews and from the Rorschach test distributed among female drug addicts, the study highlights how psychodynamic upheavals induced by pregnancy make it possible to revive the psychic deadlock at play in drug addiction. These observations are consistent with the results of existing literature, which have found that psychoanalytic aspects in pregnancy can transform drug addiction problems. However, our study underscores that these results are neither linear, nor do they hold true for all women. Moreover, this transformation remains highly fragile.
