What regulatory act was put in place to restrict the sale of pseudoephedrine (Sudafed)?

The Combat Methamphetamine Epidemic Act of 2005 was specifically designed to address the growing epidemic associated with methamphetamine production and abuse, primarily through the control of precursor chemicals used in the illicit synthesis of meth. Pseudoephedrine, commonly found in over-the-counter cold and allergy medications, is one such precursor. The Act implemented significant regulations on the sale of products containing pseudoephedrine, including limits on the quantity that can be purchased in a single transaction, requirements for customers to present identification, and mandates for maintaining records of sales.

This focused approach aims to reduce the availability of pseudoephedrine to those intending to use it unlawfully while still allowing legitimate access for consumers in need of relief from cold symptoms. The other regulatory acts mentioned, while important in their own rights, do not specifically target the control and regulation of pseudoephedrine in the same manner as the Combat Methamphetamine Epidemic Act.
