A method of dispensing medicaments may employ a drug dispensing device comprised of an upper hopper having an upper opening for receiving a medicament and a lower opening. The drug dispensing device also includes a lower hopper having an upper opening and a lower opening in a bottom portion thereof. The upper hopper defines a bulk storage chamber and the lower hopper defines a dispensing chamber. A rotatable dispensing disc is positioned in a lower portion of the dispensing chamber for dispensing medicament from the drug dispensing device through the lower opening in the lower hopper. A regulator is situated between the bulk storage chamber and the dispensing chamber for controlling the rate at which medicament moves from the storage chamber to the dispensing chamber.
