True or False: Only Schedule II (C2) drugs can be ordered using the Controlled Substance Ordering System (CSOS).

The statement is false because the Controlled Substance Ordering System (CSOS) is not limited to just Schedule II drugs. CSOS allows for the electronic ordering of controlled substances across various schedules, including Schedule III, IV, and V, in addition to Schedule II. This system streamlines the ordering process by enabling pharmacies and other registered entities to electronically order controlled substances while maintaining compliance with regulatory requirements.

This flexibility is crucial for maintaining an efficient supply chain in pharmacies, as it allows them to manage a wider range of controlled substances electronically, ensuring faster processing and reducing errors associated with paper orders. Therefore, the correct answer reflects the broader scope of substances that can be ordered through CSOS, including not only Schedule II drugs but also those from other schedules.
