Which scheduling system is used to classify controlled substances?

The correct choice is the Controlled Substance Schedule, which refers specifically to the classification system established under the Controlled Substances Act (CSA). This system categorizes drugs and substances into schedules based on their potential for abuse, accepted medical use in treatment, and the degree of dependency they may cause. The schedules range from Schedule I, which includes substances with no accepted medical use and a high potential for abuse (like heroin and LSD), to Schedule V, which includes drugs with lower potential for abuse and recognized medical uses (like certain cough preparations).

This classification framework is crucial for healthcare professionals, including pharmacists, as it helps determine the rules for prescribing, dispensing, and handling controlled substances. Trained professionals must be aware of these schedules to comply with legal regulations and ensure patient safety.

The other options do not accurately represent the existing classification system for controlled substances. A Five-Tier System or a Three-Tier System does not align with the established scheduling system recognized nationally and in Delaware pharmacy law. The term Classifications System is too vague and does not specifically refer to the exact parameters set forth in the Controlled Substance Schedule.
