[First debates regarding the legalization of drug use in Argentina at the start of the 20th century: the proposal of Dr. Leopoldo Bard and its sociohistorical context].

This paper analyzes the discourses of Argentine doctor and public health professional Leopoldo Bard using three texts on drug abuse published between 1923 and 1933. These texts embody the debates of the time regarding the role of the State, public policies at the national and regional level and, particularly, the US influence in Argentina exerted through the figure of Dr. Bard. The legislative measures and policies of that time, undoubtedly of a repressive character, were key in the State's advances into the private sphere and in the increasing importance of professional organizations in the definition of the material and symbolic borders of the socially acceptable, including those related to drug use. The multiple purposes these policies seem to satisfy are also highlighted: at the local level they enable other forms of repressing conflicts arising from immigration, while at the international level they appease US requirements.
