What is the distinctive feature of Schedule V controlled substances?

Schedule V controlled substances are characterized by their lowest potential for abuse relative to other drug schedules. This classification indicates that these substances have accepted medical uses and present a reduced risk of dependence compared to higher schedules. As a result, they are often used for medical conditions, including cough suppression and certain gastrointestinal disorders, while being subject to regulation to help prevent misuse.

The understanding of Schedule V substances also involves recognizing that while they can be available without a prescription in some jurisdictions, this is not a defining feature of the schedule itself—instead, it is determined by state law and varies by location. Therefore, while options regarding availability and accepted medical usage are relevant, they do not encapsulate the distinctive feature of Schedule V substances as effectively as the indication of their low potential for abuse.
