Under Article 60 of the narcotics control ordinance (BetmKV, SR 812.121.1) individuals and companies who hold appropriate authorisation from a federal authority must notify the agency of all domestic deliveries of controlled substances in schedules a, b or d. Reports can also be entered electronically using the MESA system. MESA is a web application that enables the individuals and companies in question to enter deliveries and quantities of preparations and active substances in the database either by entering the substance or preparation in the reporting mask or by uploading a report file.
Swissmedic then makes the data available to the responsible cantonal authorities in accordance with Art. 61 para. 3 BetmKV.
