Where should controlled substances be stored according to regulations?

Controlled substances must be stored in a secure manner to prevent unauthorized access and ensure they are handled in compliance with legal regulations. The correct answer reflects that these substances should be kept in a safe, vault, or steel cabinet, as this provides a high level of security and protection against theft or misuse. These storage options are designed to prevent access by unauthorized personnel and to minimize the risk of diversion, which is a key focus of regulations governing controlled substances.

The requirement for secure storage is particularly important due to the potential for abuse and addiction associated with many controlled substances. By using a safe, vault, or steel cabinet, practitioners demonstrate adherence to both legal standards and ethical responsibilities in safeguarding these substances.

Other storage options do not meet the necessary security standards. Regular filing cabinets, refrigerators, and locked drawers do not provide the same level of protection against theft or unauthorized access, making them inadequate for the storage of controlled substances.
