Drug control, additional performance information is needed to oversee the National Guard's state counterdrug program

" Since 1989 the National Guard has received hundreds of millions of dollars to help enhance the effectiveness of state-level counterdrug efforts by providing military support to assist interagency partners with their counterdrug activities. The program funds the drug interdiction priorities of each state Governor; counterdrug-related training to interagency partners at five counterdrug schools; and state-level counterthreat finance investigations, all of which are part of DOD's broader counterdrug efforts. Senate Report 113-176 included a provision for GAO to conduct an assessment of the state operations of the National Guard's counterdrug program. This report: (1) identifies the changes in funding for the program since fiscal year 2004, and (2) assesses the extent to which performance information is used to evaluate the program's activities. GAO analyzed the program's budgets and obligations data, performance measures, and program guidance, and interviewed knowledgeable officials. "
