You can get frost bite if you are exposed to it for too long. Also do not directly inhale air duster. Also do not ignite air duster as the chemical(s) released are quite toxic (we're talking LC50 1278 parts per million toxicity, within 60 minutes reference) 1,1,1,2-tetrafluoroethane has a nasty gas, hydrogen fluoride, as a by-product of combustion. This concludes the more-than-you-really-cared-to-know-about-air-duster presentation

Ummm compressed air should not be inhaled by jamming up your nose just in case.
As for it getting on your finger and being cold this is normal when you expand a gas that is compressed.
You know that ancient equation called
PV=nRT?
Pressure * Volume = #moles * (Rconsant) * Temperature
So as your pressure decreases and your volume increases and moles decrease your temperature will decrease as well. Namely this happens to all expanding gasses.
However the gas they call air in those cans is not air. Don't breath it, although non toxic you can sophicate.
