This article describes cases presented by experts from the legislative and medical-legal fields regarding the use of psychoactive substances among Argentinian women from 1878 to 1930. Background information is presented regarding the relationship between women and the use different drugs, medical interventions on the female body where psychoactive substances were used are analyzed, and experts’ descriptions of cases of female drug users are detailed. Experts’ discourses during this period did not attempt to comprehend the specificities of female consumption, but were rather used to position the issue of drug use as a social problem. This was done using three prototypes: the victim of a sick husband; the prostitute who encourages drug use among the weak in spirit (natural-born criminals); and the virtuous young woman who succumbs to drug addiction in spite of her father’s rule. Each figure reinforces the need for state intervention and increased social control.Este trabajo describe casos expuestos por expertos de los ámbitos legislativo y médico-legal periodístico, en los que se reporta el consumo de sustancias psicoactivas por parte de mujeres de Argentina, entre 1878 y 1930. Se presentan antecedentes sobre mujeres y usos de distintos fármacos, se analizan las intervenciones médicas que utilizan sustancias psicoactivas sobre el cuerpo femenino, y se detallan los casos de mujeres consumidoras desde las miradas expertas. En este periodo, los discursos expertos no buscaron comprender la especificidad femenina del consumo, sino promover el tema drogas como un problema. Esto se produce utilizando tres prototipos: la víctima de un marido enfermo, la prostituta que envicia a los débiles de espíritu (criminal nata), y la joven virtuosa que contraviene la ley del padre y sucumbe en la toxicomanía. Cada figura refuerza la necesidad de intervención estatal y control social.
