"The 'National Drug Control Strategy' lays out an evidence-based approach to reducing drug use and its consequences; therefore, timely and accurate data are essential to the Strategy's development, implementation, and assessment. In 2010, the Administration devoted an entire chapter of its inaugural 'National Drug Control Strategy' to strengthening the information systems that support it. This commitment carries through to the 2012 Strategy. This companion document to the 2012 'National Drug Control Strategy' compiles data from many drug-related information systems, providing a reference regarding what we know about drug use, its consequences, illicit drug production and trafficking, and other related statistics. The Administration will continue to work to strengthen these information systems in order to improve our understanding of the drug problem and develop the most effective approaches to protect public health and safety."
