National Precursor Log Exchange
Real-time tracking and blocking of meth precursors
States with laws requiring electronic tracking of products containing pseudoephedrine.

The National Precursor Log Exchange (NPLEx) is a real-time electronic logging system used by pharmacies and law enforcement to track sales of over-the-counter (OTC) cold and allergy medications containing precursors to the illegal drug, methamphetamine.
Every day, millions of people across the country rely on effective OTC cold and allergy medications for their intended use. A small percentage of people buy these same medications with the intent of diverting a component into the illegal and highly volatile drug, methamphetamine.
The National Association of Drug Diversion Investigators (NADDI) provides NPLEx at no cost to states that have legislation requiring real-time electronic monitoring of precursor purchases, and agree to use the system.
