Abstract: The present invention can ensure traceability of packaged drugs. A label printer of a drug packaging apparatus provided in a dispensing pharmacy or the like prints unique identification information, which is only one in the world issued by a numbering server on a package basis, on a label, and attaches the label to a packaging bag in which drugs are packaged by a drug packing unit. The dispensing pharmacy uploads at least drug information of the packaged drugs, to which the unique identification information is added, to a cloud server in association with the unique identification information. The cloud server unitarily manages the drug information of the packaged drugs uploaded from the dispensing pharmacy or the like in association with the unique identification information. The packaged drugs can be traced by making inquiries to the cloud server based on the unique identification information added to the packaging bag.
