The DEA's National Forensic Laboratory Information System (NFLIS) systematically collects results from drug chemistry analyses conducted by state and local forensic laboratories across the country. As a national drug forensic laboratory reporting system, NFLIS provides timely and detailed analytical results of drugs seized by law enforcement. It is a unique source of information for monitoring and understanding drug abuse and trafficking in the United States, including the diversion of legally manufactured drugs into illegal markets. Findings from NFLIS can also supplement existing drug data sources, including information from drug demand surveys and drug testing programs.
