Oral morphine : information for patients, families and friends / Robert G. Twycross, Sylvia A. Lack.

"In recent years a lot has been written about the use of morphine to treat pain in cancer. In this booklet, we have set out to answer a number of questions that patients and thier families often ask about this type of treatment. It is more for dipping into, rather than for reading straight through from beginning to end."--From preface.
