Ramzy describes the psychoanalytic treatment of a difficult case of drug addiction and maintains that it is possible to keep technically within the range of a purely interpretive approach. After briefly discussing the psychopathology of drug addition and the therapeutic difficulties related by some writers, he mentions Eissler's warning regarding the dangers in the use of parameters. The author explains his use of a 'focused' approach in technique, which he feels differs only in degree from the standard 'expectant' analysis.
