1. An apparatus for injecting a fluid into a dispensing cartridge, comprising in combination: (5) (5)

a needle having a shaft extending between a first end adapted to receive fluid and an opposing second end adapted to dispense fluid;

a reservoir adapted to store a fluid;

a fluid pump having an inlet coupled to the reservoir and adapted to receive fluid therefrom, the fluid pump having an outlet adapted to selectively force fluid therefrom, the outlet being coupled to the first end of the needle;

a cartridge holder adapted to releasably hold a dispensing cartridge to be filled; and

a needle heater disposed proximate the shaft of the needle and adapted to heat fluid therein for preventing such fluid from coagulating within the needle, wherein the needle heater includes a generally cylindrical bobbin extending around the shaft of the needle, and resistive wire coiled about the bobbin, the resistive wire being adapted to generate heat when an electrical current is conducted thereby.

2. The apparatus of claim 1 wherein the cartridge holder adapted to releasably hold a dispensing cartridge is adapted to alternately move a dispensing cartridge toward and away from the second end of the needle. (1) (0)

6. The apparatus of claim 1 wherein the fluid pump includes a pump heater adapted to heat fluid within the fluid pump. (0)

7. The apparatus of claim 1 wherein the reservoir includes a reservoir heater for heating fluid within the reservoir. (0)

8. The apparatus of claim 1 wherein the fluid stored by the reservoir is cannabis oil. (0)

9. The apparatus of claim 1 wherein the resistive wire is polymide-insulated nichrome wire. (0)

10. An apparatus for injecting cannabis oil into a dispensing cartridge, comprising in combination: (5) (4)

a reservoir adapted to store cannabis oil, the reservoir including an outlet for delivering stored cannabis oil;

a fluid pump having an inlet coupled to the outlet of the reservoir for receiving cannabis oil therefrom, the fluid pump having an outlet adapted to selectively force cannabis oil therefrom;

a needle having a shaft extending between an inlet end adapted to receive cannabis oil and an opposing outlet end adapted to dispense cannabis oil, the needle being disposed generally directly below the fluid pump, and the inlet end of the needle being connected directly to the outlet of the fluid pump by a valveless connection for receiving cannabis oil directly therefrom; and

a cartridge holder adapted to releasably hold a dispensing cartridge to be filled with cannabis oil.

11. The apparatus of claim 10 including a needle heater disposed proximate the shaft of the needle and adapted to heat fluid therein for preventing such fluid from coagulating within the needle. (0)

12. The apparatus of claim 10 wherein the cartridge holder is movable and is adapted to alternately raise a dispensing cartridge toward the outlet end of the needle and lower the dispensing cartridge away from the outlet end of the needle. (2) (0)

16. The apparatus of claim 10 wherein the reservoir is positioned directly above the fluid pump, whereby cannabis oil stored by the reservoir can drain from the lower end of the reservoir directly into the inlet of the fluid pump. (0)

17. The apparatus of claim 10 wherein the fluid pump includes a pump heater adapted to heat fluid within the fluid pump. (0)

18. The apparatus of claim 10 wherein the reservoir includes a reservoir heater for heating fluid within the reservoir. (0)
