What is true about Schedule V substances?

Schedule V substances include a range of medications that are considered to have lower potential for abuse compared to other controlled substances. What distinguishes Schedule V from other schedules is that, in certain circumstances, they can be sold without a prescription. This is permitted in some states, often with regulations regarding the quantity that can be purchased and the age of the buyer.

This flexibility allows for the direct consumer availability of certain medications, such as cough preparations with less than a specific amount of codeine or other medications deemed less addictive. Therefore, under particular state laws, these substances may be accessed without the need for a prescription, making this statement about Schedule V substances accurate.

In contrast, the other choices present limitations or inaccuracies when it comes to the legal status and handling of Schedule V substances. They are not illegal to distribute, they can be prescribed, and they certainly have accepted medical uses, further highlighting the correctness of the chosen answer.
