"A detailed examination of how public policy is made ... with insightful research, Mallinson and Hannah unravel the patchwork of marijuana policy across the country." (Kirkus Reviews) "What explains the rapid shift in pro-cannabis public sentiment and state policy in a country that has spent billions of dollars on the War on Drugs? This exciting book illuminates this question and others, increasing our understanding of one of the most remarkable policy shifts of the past quarter-century ... Clearly written, accessible, and timely." - Andrew Karch, author of Democratic Laboratories: Policy Diffusion among the American States "In Green Rush, Daniel J. Mallinson and A. Lee Hannah examine the spread of marijuana policy laws in the American states, focusing on the adoption of legal medical and recreational marijuana policies. They show that states [ can] defy national policy and innovate when the national government ... fails to act ... and that activists and entrepreneurs can leverage federalism by pursuing policy goals in states." - Donald P. Haider-Markel, editor of The Oxford Handbook of State and Local Government "Mallinson and Hannah provide the reader with an excellent overview of policymaking designs and theories since their analysis takes up so many different dimensions of the policy process in the United States ... Green Rush charts the policy changes themselves, but also pays attention to changing public opinion around cannabis and shifts in the war on drugs." - Lilly J. Goren, Professor of Political Science, Carroll University
