    • NIST/NIJ Characterized Authentic Drug Sample (CADS) Project

    Metadata Updated: July 9, 2025

    Development and validation of new analytical or data tools for seized drug analysis require demonstration of the approach's ability to accurately detect the components of complex, realistic drug mixtures. However, gaining access to these types of samples, or the data from these types of samples, can be difficult. To help address this gap, the Characterized Authentic Drug Samples (CADS) project aims to: 1) source authentic seized drug samples from collaborating forensic laboratories, 2) characterize the samples using a variety of analytical tools, and 3) make available small amounts of the samples, as well as the corresponding data, to researchers and practitioners.This dataset provides pdf reports of analysis for all available CADS samples.Disclaimer: Certain commercial products are identified in order to adequately specify the procedure; this does not imply endorsement or recommendation by NIST, nor does it imply that such products are necessarily the best available for the purpose. A portion of this work was supported by the National Institute of Justice, Office of Justice Programs, U.S. Department of Justice.
