The present study aims to reveal the structure of positions in the field of addiction through the analysis of doctoral theses read in Spain. The source consulted for the selection of the theses was TESEO. Searching for the keywords drug abuse, alcoholism, drug effects and drug addiction treatment during the period 1976-2017 produced 728 theses. The most productive period is 2013-2017, with 208 (28.6%) doctoral theses. The overall rate of publication is increasing, but in the period 2003-2007 output decreased significantly to 5.2% of the total. The university contributing the most theses is the University of Valencia. The academic who has supervised the most theses is Alfonso Velasco Martín, and Emilio Ambrosio Flores is the researcher who has participated most on examining committees. The analysis of the participants in the doctoral thesis process shows a gradual increase of women in authorship, in thesis supervision and as examiners. In terms of subject, the most frequently treated aspects are those related to psychology, pharmacology and medical sciences.The analysis of doctoral theses on substance abuse provides an overview of the structure and the most influential participants in this area. Increasing public concern and the creation of specific groups and research units are reflected in the growth of scientific output.
