This module of the Toolkit provides information about drug precursors and the international precursors control system, as well as the two key elements critical to prevent chemicals from reaching clandestine laboratories for the illicit manufacture of drugs, namely (1) monitoring of legitimate international trade, and (2) investigations into suspicious shipments, attempted diversions and seizures of precursors.

The module includes links to information and materials available for all interested readers, as well as links restricted for Government officials. If you are an official from a Competent National Authority (CNA) and do not yet have access or forgot the user ID or password, please contact: incb.precursors@un.org
