Harriman police were dispatched to Walgreens recently on a report that several people had purchased medicines containing pseudoephedrine in close intervals.
The call resulted in the arrest of a Wartburg man and woman.
Jeffery Wayne England and Nicole Denise Eubanks are each charged with initiation of the process to manufacture methamphetamine.
Pseudoephedrine is found in common cold and allergy medicines and is the main precursor to making meth.
Harriman police said Eubanks was attempting to make a purchase when they arrived at the store.
