Is addiction a brain disease or development?
Lewis treats addiction as a self-perpetuating learning loop in a plastic brain, not a deviation from a neuronormative healthy brain.

What they did
Lewis attacks the chronic, relapsing brain-disease model and the funding bias that favours it. He notes many people quit without treatment, then sketches alternatives (choice, environment, self-medication) that usually ignore detailed brain mechanisms. His own account is developmental learning plus neuroplasticity.
What they found
Self-perpetuating attraction is a feedback loop between experience and synapses, not proof of disease. Brain-disease thinking searches for neuronormativity and repair; a developmental model treats the brain as an open system that can change in many directions. Recovery is conceived from within, not dictated by professional norms.
The limits
What it doesn't show
This is a theoretical essay, not a new imaging study. It does not measure quit rates itself. ‘Without treatment’ citations are from the wider literature.
Key terms
- Brain disease model
- Addiction as a chronic, relapsing disease of hijacked brain circuits.
- Neuroplasticity
- The brain’s capacity to change with experience, taken as a first principle.
- Neuronormativity
- The idea of a standard neural architecture that addiction violates and medicine repairs.
- Developmental-learning model
- Addiction as a phase of individual development consolidated through learning.

Common questions
Does Lewis ignore the brain?
No. He thinks rivals to the disease model usually say too little about specific brain processes.
Why isn’t a feedback loop a disease?
Self-perpetuating attractions are not, by themselves, pathology.
How should change be pursued?
From within individual development, not as repair to a normed organ.
