DES MOINES, IOWA (AP) -- Gov. Chet Culver has signed a measure that tightens the sale of the drug pseudoephedrine, which can be used to make meth.
The bill tracks multiple purchases of the nonprescription cold medicine.
Under the measure, customers buying pseudoephedrine must sign an electronic log that records the purchase, a move aimed at building a registry where authorities can keep track who is buying the drug.
Currently, customers sign a paper log.
