This is a book about a controversial issue—whether doctors should be licensed by law to supply lethal drugs to terminally ill patients. It is written primarily for those who want to find a path through the thickets of a subject that transcends many fields of expertise. The authors have considerable experience of the matters about which they write, involving both research and hands-on medical care of dying people. They are not neutral about 'assisted dying': they are not convinced that the law is in need of change. However, the book employs an evidence-based approach and brings much-needed clarity to such complex issues as how the existing law works, how medical practice operates at the end of life, and what has been the experience of jurisdictions that have gone down the 'assisted dying' road. Above all, the book shows respect for the views of others who may judge the evidence differently.
