Which of the following is true about CIV substances?

• A. They have a high potential for abuse.
• B. They have accepted medical uses with limited physical dependence.
• C. They are entirely banned.
• D. They have no medical uses.

Answer: (B)

CIV substances, or Schedule IV controlled substances, are categorized as having accepted medical uses, which is precisely why the choice highlighting this aspect is accurate. These substances carry a lower potential for abuse compared to higher schedules, such as Schedule I or II drugs. While they can lead to limited physical or psychological dependence relative to substances in higher schedules, the key point here is their recognized therapeutic value in medical settings, making them lawful for prescription and use.

In contrast, the other options mischaracterize CIV substances. For instance, classifying them as having a high potential for abuse does not apply, as they are considered safer and less prone to abuse than those in higher schedules. The idea that they are entirely banned is incorrect; they are legal under specified regulations due to their legitimate medical applications. Similarly, asserting that they have no medical uses is false, as many CIV drugs treat various conditions effectively. Thus, their designation implies a balance between therapeutic potential and risk, which is central to understanding their classification in the context of controlled substances.
