I'm going to lean towards no, it's not a form of forced induction, but it all depends on your definition of FI.
Technically, a naturally aspirated engine is one that "breathes" on it's own. That is, all of it's incoming charge is pulled into the cylinder via the negative pressure developed during the intake stroke. (And perhaps a bit due to resonance supercharging or exhaust scavenging, but thats another topic).
When I think forced induction, I see the term "forced" relating to "additional mass flow" or plain and simple "more air than the engine would normally be able to pull in on it's own".
Nitrous oxide is simply a chemical injected into the induction system. The overall mass of air/fuel/NO2 mixture going into the engine remains about the same whether the N02 is being injected or not. Sure, the thermal breakdown of the N02 results in a higher oxygen charge density, but nothing is "forcing" additonal air into the engine.
It's all a technicality anyways, but I'll keep turbos and superchargers in the F.I. category and N02 in the N02 category.

According to NHRA it is and I also feel it is as well.
The whole reason why nitrous makes more power over gasoline is because it has oxygen bonded to the nitrogen and with more O2 you can shove more fuel in to make more power. Sounds exactly like a turbo/SC minus the compressor.

i think no because its not creating boost
I guess it's the whole "forced" part that I have a problem with. You're not "forcing" nitrous into the engine and thus creating boost.

This is true, you are spraying nitrous into the intake.
I look at it in the sense that if it's not drawn in by negative pressure, then it's been forced either via air itself or by inducing more particles of oxygen.
Now, a car with nitrous, is it naturally aspirated or not?
