Which substance is regulated under the Combat Methamphetamine Epidemic Act (CMEA) of 2006?

Pseudophedrine is regulated under the Combat Methamphetamine Epidemic Act (CMEA) of 2006 due to its role in the illicit production of methamphetamine. The CMEA was enacted to address the growing concern about methamphetamine abuse and the ways in which over-the-counter medications containing pseudophedrine were being misused to manufacture this dangerous drug.

The law established strict controls on the sale of pseudophedrine, classifying it as a "scheduled listed chemical product." This means that there are limits on how much can be purchased at one time and requirements for the buyer to provide identification during the purchase. These measures are intended to reduce the availability of pseudophedrine for illegal use while still allowing it to be used for legitimate medicinal purposes, such as a decongestant.

In contrast, the other substances mentioned—oxycodone, codeine, and acetaminophen—are regulated under different laws and regulations. Oxycodone and codeine are narcotics that fall under the Controlled Substances Act and are categorized based on their potential for abuse. Acetaminophen, commonly used for pain relief and fever reduction, does not have the same controlled status and is not implicated in methamphetamine production.
