'Monaghan does not pretend to provide a complete account of UK drug policy-making. But with this rich and thoughtful exploration of an important topic, he succeeds in his ambition to contribute to a more reasoned debate over the use of evidence in politicised areas.' - Susanne Macgregor in Journal of Social Policy "Monaghan’s discussion of drug classification provides a vehicle for some interesting and insightful reflections on the nature of the relationship - or rather relationships -between policy and evidence." Marcus Roberts in DrugLink "This excellent and careful analysis of the dynamic interactions between evidence and policy in UK Drug Policy is exactly what is needed to move forward our thinking about evidence-based policy. I strongly recommend it to all those interested in the prospects for increasing the rationality of policy through reference to evidence." Sandra Nutley, Professor of Public Management, University of Edinburgh Business School, Edinburgh "This is well worth reading: an evidence-based book on evidence-based policy making. It both contributes to our understanding of the complexity of UK drug policy making and adds an important dimension to the vexed issue of how evidence affects policy." Louise Shaxson in Public Policy and Administration "Evidence is rather like a befuddled teenager - at once uncertain and shy and then pig-headed and brash. Eventually, however, it matures and finds its place. Monaghan's masterly book traces this coming of age in the contentious area of drug policy. It is a key contribution to the field."
