Resumen:
The authors thought of the idea for this exploratory paper for Drugs and Alcohol Today after visiting a local prison on the outskirts of Madrid from which these field notes are taken. The authors have also had informal conversations with the contacts working in the Spanish Prison service. When the authors looked at some of the literature around the relationships between drugs and prisons in Spain, the authors found lots of statistics, and material which either said there were lots of drugs in prison or literature which presented over-medicalised processes of drug treatment. In short, the authors found few studies which could bring to life the kind of problems drugs bring to the prison and how the dynamics of the prison are not only directly impacted by drug use but also as drug dealing/trafficking. The paper aims to discuss these issues.
