Which of the following is NOT required when selling a poison?

When selling a poison, it is not required to include the name of the manufacturer. This requirement can vary by state laws, but generally, what is prioritized in the documentation of a poison transaction includes specific identifying information related to the substance itself and the parties involved in the sale.

Including the amount and kind of poison ensures regulatory compliance and safety, as it allows for tracking of potentially hazardous substances. The name and address of the seller is crucial for accountability and traceability, ensuring that there is a legitimate source for follow-up if issues arise from the use of the poison. A prescription from a physician is often a requirement for drugs that have dangerous potential and must be dispensed under care guidelines, but in the context of selling poisons, it typically isn't mandated.

Thus, while the name of the manufacturer may be beneficial for specific tracking and brand identification, it is not a universally required element when selling poisons.
