What must a purchaser do after showing ID to buy pseudoephedrine?

When purchasing pseudoephedrine, it is a requirement for the buyer to sign a logbook. This process is in place to help ensure that the sale of pseudoephedrine, which can be used to manufacture methamphetamine, is regulated. The logbook typically records pertinent details such as the purchaser's name, address, the amount of pseudoephedrine being purchased, and the date of the transaction. This measure is part of the efforts to monitor and control the sale of products containing pseudoephedrine and to discourage illegal activities associated with its misuse.

Signing the logbook serves as an important safeguard for both pharmacies and law enforcement, as it helps maintain traceability and accountability in the distribution of these regulated substances.
