Two years ago, the President's National Drug Control Strategy set the ambitious goals of reducing past-month, or "current," use of illegal drugs by 10 percent over two years and 25 percent over five years. The Strategy stated at that time that the Administration would measure its success by results.

Those results are in; we have exceeded our two-year goal of reducing drug use among young people, with the most recent survey showing an 11 percent drop between 2001 and 2003 in drug use by teenagers. Among teens, some drugs—such as LSD—have dropped to record low levels of use. For others, we are seeing the lowest levels of use in almost a decade.

Our effectiveness in driving down drug use can be measured in many other, complementary ways. Many such measures are included in this companion volume to the National Drug Control Strategy, including supply as well as production measures.
