Which of the following is NOT a product that requires ID and sales logs under the Combat Methamphetamine Epidemic Act of 2005?

Under the Combat Methamphetamine Epidemic Act of 2005, certain products containing specific ingredients are regulated due to their potential use in the illegal production of methamphetamine. Both ephedrine and pseudoephedrine are closely monitored under this law, as they can be used as precursors in meth synthesis. Therefore, sales of these products require a valid photo ID and must be recorded in sales logs to track usage and prevent abuse.

Phenylpropanolamine also falls into a similar category, as it is an ingredient that has been linked to the illicit production of methamphetamine. Thus, it too is subject to the same ID and logging requirements.

Diphenhydramine, on the other hand, is an antihistamine primarily used for allergy relief, and it does not have the same potential for illicit use in methamphetamine production. As a result, products containing diphenhydramine are not subject to the ID and sales log requirements outlined in the Combat Methamphetamine Epidemic Act. This distinction helps to streamline the regulatory process, focusing on substances that pose a higher risk for misuse.
