Kleiman, Caulkins, and Hawken have pulled a great coup with this volume. They managed to condense, in very readable terms, layer upon layer of scholarly research about the many facets of drug policy. Their encyclopaedic knowledge of the subject matter, combined with a breezy style, allows the reader to quickly make sense of complex and controversial issues. This is not, however, a dry reference book: the authors have strong, sometimes eccentric opinions that will not be to everyone's liking. But that is indeed one of this book's strenghts: it allows its pages to feel as an animated conservation with three very smart people.
Anyone with even a passing interest in drugs or drug policy should buy this book; and for policymakers involved in drug issues, this should be required reading.
