Drug use and teenage pregnancy are prominent issues in the current context. The scope of this study is to relate adolescence and pregnancy to the issue of drug use. The objective of the study is to investigate the establishment of the link between the adolescent mother drug user and her future baby, during pregnancy and/or puerperium, in the context of drug use. The research methodology used is of a qualitative nature, through a unit case study. Data were collected using a semi-targeted interview script as the main instrument and their subsequent analysis was carried out through thematic categories in the light of psychoanalytical theory. The main result of this study is the possibility of the existence of a link between the adolescent mother and her baby in the context of drug use, allowing the conclusion that the same adverse social conditions that lead to drug use, generate the difficulty of assisting the children, not always directly resulting from affective bluntness or other psychic alteration by drug use. The conclusion points to the fundamental importance of transferencial processes and bonds.
