This article proposes a theoretical framework on the role of pharmaceuticals in transforming perspectives and shaping contemporary subjectivities. It outlines the significant role drugs play in three fundamental processes of social transformation in Western societies: medicalisation, molecularisation and biosocialisation. Indeed, drugs can be envisaged as major devices of a pharmaceutical regime, which is more akin to the notion of dispositif, as used by Foucault, than to the sole result of high‐level scheming by powerful economic interests, a notion which informs a significant share of the literature. Medications serve as a key vector of the transformation of perspective (or gaze) that characterises medicalisation, molecularisation and biosocialisation, by shifting our view on health, nature and identity from a categorical to a dimensional framework. Hence, central to this thesis is that the same underlying mechanism is at work. Indeed, in all three processes there is an evolving polarity between two antinomic categories, the positions of which are constantly being redefined by the various uses of drugs. Due to their concreteness, the fluidity of their use and the plasticity of the identities they authorise, drugs colonise all areas of contemporary social experiences, far beyond the medical sphere.
