A drug packaging unit is disclosed. The drug packaging unit includes a storage portion separately discharging a plurality of units of a drug, a supply portion supplying the drug to a drug packaging member, a detection portion detecting a drug supply error by detecting the drug passing through the supply portion, an adjustment portion adjusting the number of units of drug discharged out of the supply portion, and a driver/controller individually driving the storage portion and the supply portion, thereby putting the drug on standby to be discharged. With this structure, it is possible to reduce a drug packaging time and it is easy to control drug supply.
