Who is responsible for reporting a loss of controlled substances after the shipment has been received?

The purchaser is responsible for reporting a loss of controlled substances after the shipment has been received. This responsibility lies primarily with the entity that receives the controlled substances since they are accountable for securing and properly managing the inventory.

In situations where a discrepancy occurs, such as missing or damaged controlled substances after receipt, the purchaser must notify the appropriate authorities, including the Drug Enforcement Administration (DEA) and possibly the state regulatory agency, depending on state laws. The purchaser has direct knowledge of their inventory and is typically the party who discovers the loss when conducting their inventory checks or during routine operations.

The supplier's responsibility generally pertains to the shipping and delivery of the ordered substances and ensuring that they are packaged appropriately for transport. They are not involved in the accountability of the products once they reach the purchaser's location. Moreover, while both parties may have roles in the overall handling of controlled substances, the immediate responsibility for reporting losses post-receipt lies with the purchaser. The involvement of regulatory agencies comes after a report has been made to address compliance and investigate potential issues.
