Which of these substances is not regulated under the Combat Methamphetamine Epidemic Act?

Cough syrups containing codeine are not regulated under the Combat Methamphetamine Epidemic Act because this federal legislation specifically focuses on the control of products that can be used to manufacture methamphetamine, primarily those containing pseudoephedrine.

The Act, enacted in 2005, imposes restrictions on products containing pseudoephedrine due to its potential use in the illicit synthesis of methamphetamine. These regulations include limits on the quantity that can be purchased, age restrictions, and record-keeping requirements for sales.

While amphetamines, OTC pseudoephedrine, and pseudoephedrine itself are directly related to the Act's intent to combat methamphetamine production, cough syrups containing codeine are classified differently. Codeine is a controlled substance regulated mainly under the Controlled Substances Act, requiring different oversight compared to pseudoephedrine.
