In 2005 Kentucky and dozens of other states passed laws restricting the sale of products containing pseudoephedrine (PSE), the key ingredient for meth production. These laws closely followed similar legislation enacted in Oklahoma in 2004. States that restricted PSE began seeing immediate declines in meth-lab responses. Those declines, however, were short lived, as meth users and cooks began an activity known as ‘smurfing,’ a process of purchasing small amounts of PSE at multiple locations.

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 This system has the ability to alert the pharmacist at the point of sale when an individual is attempting to exceed legal product limits.

In 2012, Senate Bill 3 was passed that further limits the amount of over-the counter allergy and cold medication that may be purchased without a prescription.
