The utility model relates to a medicine taking detection mechanism, a drawer and a medicine cabinet, the medicine taking detection mechanism comprises a tray, a detection assembly and a moving assembly, the detection assembly comprises a movable part and a detection part, the detection part is arranged on the tray, and the movable part can move relative to the detection part; the moving assembly is arranged on the tray, and the moving assembly can push the medicine on the tray to move to abut against the movable part so that the movable part can trigger the detection part; and when the medicine is taken, the movable part can be reset to release the triggering of the detection part. When the medicine is not taken out, the movable part is subjected to the abutting force of the medicine, so that the movable part triggers the detection part, and when the medicine is taken out, the abutting force borne by the movable part disappears, so that the movable part can reset to relieve triggering on the detection part.
