Controlled substance inventories must be made for which of the following?

Controlled substance inventories must be completed for each registered location where controlled substances are stored or dispensed. This is because the Drug Enforcement Administration (DEA) requires a separate inventory to be maintained for each pharmacy or healthcare facility where controlled substances are handled. Each registered site must account for the quantities and types of controlled substances on hand to ensure compliance with regulatory standards and to facilitate accurate tracking and control over these substances.

Maintaining an inventory for each registered location ensures that records reflect the actual stock at each site, helping to identify discrepancies or potential issues related to theft, loss, or over-prescribing. Each pharmacy's unique license and registration represent distinct operational controls, necessitating independent inventories.

In contrast, while state regulations may also influence pharmacy operations, the federal requirements set forth by the DEA emphasize the need for an inventory at each distinct registered location, as opposed to aggregating data across multiple states or facilities. Therefore, the focus on individual registered sites is essential for meeting legal and safety standards in the handling of controlled substances.
