What federal law sets daily and monthly limits on OTC sales of pseudoephedrine and ephedrine?

The Combat Methamphetamine Epidemic Act is the correct answer because it was enacted to address the illegal production of methamphetamine, which can be synthesized using pseudoephedrine and ephedrine—ingredients commonly found in over-the-counter (OTC) cold and allergy medications. This legislation establishes specific requirements for the sale of these substances, including limiting the quantity that a consumer can purchase in a single transaction, as well as over the course of a month.

The Act also mandates that pharmacists or pharmacy technicians must keep a logbook of sales, which includes customer identification and addresses, to help track and prevent misuse of these medications. By putting these measures in place, the law seeks to reduce the potential for abuse while still allowing access for legitimate medical use.

Other options, while they may pertain to drug regulation in different contexts, do not specifically enforce such limitations on the sale of pseudoephedrine and ephedrine.
