What is characterized by limited medical use and relatively low potential for abuse?

The correct answer is Schedule V. Schedule V substances are characterized by their limited medical use and relatively low potential for abuse compared to other schedules of controlled substances. These drugs typically contain lower concentrations of certain narcotics and are often prescribed for specific medical conditions that warrant their use. Because of their lower potential for abuse, they are subject to less stringent regulations than those classified in schedules with higher abuse potential.

In contrast, Schedule I drugs are considered to have no accepted medical use in the United States and a high potential for abuse, making them completely illegal. Schedule II and Schedule III drugs possess a higher potential for abuse and are more strictly controlled than Schedule V substances. Schedule VI is not a classification recognized in the federal scheduling, as it pertains to state-specific laws regarding certain substances. Understanding these classifications helps inform proper handling, prescribing, and regulatory compliance regarding controlled substances.
