What is the maximum amount of codeine that can be sold to an individual in a single sale?

The correct answer reflects regulations regarding the sale of codeine preparations. In many jurisdictions, including Tennessee, the sale of over-the-counter medications containing codeine is regulated due to the potential for misuse and abuse associated with opioids.

According to federal regulations, products containing codeine are classified as Schedule III controlled substances when they are combined with other medications and are available for purchase without a prescription. The limit for codeine in such mixtures is often framed in terms of the total amount per transaction.

The limit of 120 mL in a single sale is in line with both federal guidelines and state laws that aim to mitigate the risk of addiction and ensure responsible dispensing practices. This regulation is put in place to regulate how much codeine an individual can obtain at once without a prescription, thereby controlling availability and monitoring use.

The other quantities listed exceed the typical limits set by regulatory bodies, making them impractical or incorrect options for safe and legal sales of codeine-containing products. Thus, the maximum amount that can be sold to an individual in a single sale is 120 mL, aligning with the established regulations in Tennessee and similar jurisdictions.
