A filling device for filling a removable medication cartridge for the smart medication dispenser is provided. The filling device includes a stationary fill plate with a plurality of openings. The openings are shaped to allow the passage of medications through the fill plate. The cartridge is removably positioned vertically below the fill plate and with the chambers of the cartridge being aligned with the openings of the fill plate. A gate is positioned vertically below the fill plate and above the cartridge. When in a closed position, the gate covers the openings from beneath the fill plate, and movement of the gate to an open position causes at least one medication to fall through at least one of the openings from above the stationary fill plate into at least one of the chambers in the cartridge prior to removal of the medication cartridge with the medications received within the chambers.
