This paper critically examines methadone treatment from the perspective of adult and community education and questions the absence of rehabilitation. It identifies biomedicine and the methodology of evidence based medicine as the discourses that determine our understanding of addiction and treatment. It is especially critical of psychiatry for the over medicalisation of addiction treatment and the communities uncritical acceptance of the assumptions of medicine. The paper then looks at the Crinan project, as a model of good practice in drug treatment and asks what makes adult and community education an effective component of treatment that works uniquely in a way that medical model does not?
