摘要：These themes apply with considerable force to drug control policy. In 2001, the National Research Council (NRC) Committee on Data and Research for Policy on Illegal Drugs, which I chaired, found that society faces huge uncertainties when attempting to predict the consequences of alternative drug control policies.5 In its final report, the committee called attention to “a woeful lack of investment in programs of data collection and empirical research that would enable evaluation of the nation’s investment in drug law enforcement.”6 It called on the federal government to remedy this serious deficiency, observing that “[i]t is unconscionable for this country to continue to carry out a public policy of this magnitude and cost without any way of knowing whether and to what extent it is having the desired effect.”7
