Damage that can be cause is by improperly setting up your system... nitrous gives instant tq and it creates a shock from that instant power that can overwhelm stock engine parts.. But thats not till you ge to 150+... Im runing 75shot and its doing really good..

True, Nitrous Oxide is not a Fuel at all. It simply introduces a way of adding more Oxygen in order to allow more fuel to be burned at a higher rate.
The Engergy comes from the fuel not the Nitrous. This engergy accellerated by the Nitrous procudes tremendous amount of addtional heat or force to move those cylinders up and down more quickly. If the fuel mixture and the timing are sufficiently set and retarded at the time of this delivery then there is nothing to worry about but if the engine's timing is too high or there is not enough fuel delivered to the pistons then you have a "Lean" condition which causes detonation which is like hitting your cylinders with a sledghammer. Over time this will cause broken rods or even holes burned into the top of the cylinders. Especially if you don't have forged internals.
Now with a mild set up of 55 or 65 shot of Nitrous this is not as common as with a 100 + shot of Nitrous on a car that isn't really set up for Nitrous.
Check out this webpage. It has some Great info and tips about using Nitrous Oxide. Very imformative:
