Final answer:
The CMEA sets daily and monthly purchase limits on the sale of pseudoephedrine to curtail its use in methamphetamine production.
Step-by-step explanation:
The CMEA (Combat Methamphetamine Epidemic Act) sets specific limits on the over-the-counter sale of pseudoephedrine. The correct answer to the question is A) Daily purchase, monthly purchase. This legislation imposes restrictions on how much pseudoephedrine an individual can buy daily and in a given month to prevent the diversion of pseudoephedrine for the production of methamphetamine.
Methamphetamine abuse is a significant public health concern, as it leads to various physical and psychological problems. Medications containing pseudoephedrine, which can be used to create methamphetamine, have been regulated to curb the availability of materials needed for illicit drug production.
