This work tries to expose the difficulties that are created from the approach of the problematic consumption of substances conceiving the same as an emergent of the society of consumption. The National Law of Mental Health 26.657, raises the interdisciplinary, intersectoral and integral attention of mental pathologies, including in its article 4 addictions. This approach gives rise to the encounter / disagreement of different theoretical frameworks with their specific implications. Implementing this law involves the intersection of speeches from different disciplines and social actors, generating obstacles on several occasions. Metaphorically an epistemic Babel, a heterogeneous set of theories that complicates its implementation. The axes to make the exposed visible will be the representations, the prejudices, the accessibility to the health and the diverse criteria between different current paradigms.
