The National Forensic Laboratory Information System (NFLIS) is a program of the Drug Enforcement Administration (DEA), Diversion Control Division. The program consists of three components that complement each other to provide a holistic picture of the drugs analyzed by the U.S. forensic community.

As the most mature data system, the NFLIS-Drug component systematically collects drug identification results and associated information from drug cases submitted to and analyzed by Federal, State, and local forensic laboratories. These laboratories analyze controlled and noncontrolled substances secured in law enforcement operations across the country, making NFLIS-Drug an important resource in monitoring illicit drug use and trafficking, including the diversion of legally manufactured pharmaceuticals into illegal markets. NFLIS-Drug includes information on the specific substance and the characteristics of drug evidence, such as purity, quantity, and drugs reported in the same case. These data are used to support drug scheduling decisions and inform drug policy and drug enforcement initiatives nationally and in local communities around the country.

In 2019, DEA expanded the NFLIS program to include (1) public and private toxicology laboratory (NFLIS-Tox) data regarding postmortem and antemortem toxicological testing and (2) medical examiner and coroner office (NFLIS-MEC) data regarding deaths in which drugs were identified. These two continuous data collection programs complement NFLIS-Drug and support the DEA's drug regulatory and scheduling efforts.

If your laboratory or MEC office would like to participate in NFLIS, review DEA's FAQs document to determine your entity's eligibility to participate in NFLIS and to review other information about each NFLIS component and the next steps for participation. You may also contact DEA at
