This compact and innovative book tackles one of the central issues in drug policy: the lack of a coherent conceptual structure for our thinking about drugs. Battin and her contributors lay a foundation for a wiser drug policy by promoting consistency and coherency in the discussion of drug issues and by encouraging a unique dialogue across disciplines. The book is written accessibly with little need for expert knowledge, and will appeal to a diverse audience of philosophers, bioethicists, clinicians, policy makers, law enforcement, legal scholars and practitioners, social workers, and general readers, as well as to students in areas like pharmacy, medicine, law, nursing, sociology, social work, psychology, and bioethics.
