Which of the following best describes the purpose of categorizing controlled substances?

The purpose of categorizing controlled substances is primarily to regulate prescription practices and prevent misuse. This classification system is designed to monitor and restrict access to drugs that have a high potential for abuse or addiction, such as opioids, stimulants, and sedatives. By placing these substances into categories with different levels of restrictions, regulatory agencies can enforce laws that control how these substances are prescribed and dispensed.

This categorization fosters a structured approach that ensures that these powerful medications are only used when necessary and that they are prescribed by qualified practitioners who understand the implications of their use. The aim is to strike a balance between providing essential medications to patients who need them—such as for pain management or mental health issues—and protecting public health by minimizing the potential for abuse and addiction. Through this regulation, monitoring, and guidance, healthcare providers are encouraged to use these substances responsibly while also keeping a check on patient's safety.
