What is the rule regarding the counting of controlled substances during an inventory?

The rule regarding the counting of controlled substances during an inventory is that Schedule II (CII) substances must be counted exactly, while other schedules (CIII, IV, and V) can generally be estimated unless the container holds more than 1,000 units. This reflects the heightened level of regulation and scrutiny that applies to CII substances due to their potential for abuse and dependence.

For CIII and CIV substances, estimation is permissible, which allows for a practical approach to inventory that recognizes the lower risk associated with these categories compared to CIIs. However, if a bottle contains more than 1,000 units, even CIII and CIV substances must be counted exactly to ensure accuracy in inventory management and compliance with regulations. This rule helps to maintain a tight control over substances that could lead to misuse while offering some flexibility with those deemed to be less risky.
