A drug delivery device comprising a housing, said housing comprising:

i) an upper barrel at one end of the device which houses a generator of a force capable of pushing a drug from a packaging into a human or animal body;
and
ii) a lower barrel, at the end remote from the upper barrel, which houses:
a) a packaged drug assembly;
b) a striker to cause the drug to be pushed from the packaged drug assembly;
c) a receiver for receiving the packaged drug assembly;
d) a trigger device;
and
said lower barrel being in operative communication with said upper barrel;
and wherein the packaged drug assembly and striker are slidably mounted in the device, and pushing the device against the skin with sufficient force causes the packaged drug assembly and striker to slide up the lower barrel and the device to be primed and actuated.
