What are the requirements to purchase Sudafed in Alabama?

To purchase Sudafed in Alabama, the correct requirement is that individuals must be 18 years of age or older, and they must provide a form of identification as well as a signature. This regulation is in place due to the active ingredients in Sudafed, which can be used to manufacture methamphetamine if obtained in large quantities. The age restriction ensures that younger individuals do not have easy access to products containing pseudoephedrine, which can be misused. The requirement for ID serves to verify the purchaser's identity and age, while the signature acts as a form of acknowledgment of the transaction.

The combination of these regulations helps control the sale of pseudoephedrine to prevent its illicit use while still allowing legitimate consumers to access the medication under controlled circumstances. Other options do not accurately reflect Alabama's regulations, as being a registered voter or a resident does not specifically tie to the purchase requirements for Sudafed, and there is no mandate for a prescription or passing a background check for just purchasing the product under normal consumer circumstances.
