Do you consider nitrous NA or Boost?

According to pretty much every motorsports sanctioning body, nitrous is a "power adder". Forced induction is also a "power adder". So, nitrous is not NA or boosted.

Thanks everyone for your opinion. I dont consider it boost but it is a power adder just like adding an intake or bigger diameter exhaust or headers.

What is nitrous? Really fricken cold air being forced into the engine.. How is that not boost? At any rate. It's a power-adder and NOT naturally aspirated. You can consider it boosted or not, that's up to you, I do, but some people call "soda" "pop" so it's whatever.

Nitrous Oxide is N2O (2 Nitrogen atoms and 1 Oxygen atom bonded together).
Under the heat/pressure of a combustion chamber, the bonds break and you end up with 2 Nitrogen Atoms and 1 Oxygen atom roaming around. SO it's 1/3 Oxygen.
Normal air (N/A) is only 15-21% Oxygen (depending on atmospheric conditions such as humidity, pressure and altitude) For you geeks "sea level" @ ideal conditions (low humidity) is considered 21% (20.95% for you uber geeks)
So by using N20, you're getting 33% oxygen vs 15-21% oxygen. That my friends is what "boost" does. It crams more air (and thus oxygen) into the cylinder. One does it via pressure (Supercharger/Turbo) one does it via chemistry (N2O). They are somewhat analogous. N20 has the added benefit of cooling the intake air charge, which makes the gas in the cylinder more dense, which means more oxygen...which also adds power.
And for you eco weenies out there, consider this.
Nitrous oxide gives rise to NO on reaction with oxygen atoms, and this NO in turn reacts with ozone. As a result, it is the main naturally occurring regulator of stratospheric ozone. It is also a major greenhouse gas and air pollutant. Considered over a 100 year period, it has 298 times more impact per unit weight (Global warming potential) than carbon dioxide.
For those of you out there who are wondering...why not just inject straight oxygen rather than N20. The answer is Pure Oxygen enviornment is bad. Really really bad. Stuff you would swear can't burn WILL BURN In the presence of PURE Oxygen. Read this...
Pure Oxygen is also a powerful OXIDIZER! Put a bit of steel into a pure oxygen environment and you can WATCH the rust form before your eyes, it's that fast of a reaction. Ditto for aluminum (Aluminum oxide) and nearly all metals, plastics, rubbers and other materials used in an engine. That's why no-one uses "pure oxygen". Something NASA had to learn the hard way. (via fire and oxidation).

Nitrous Oxide is way, way more than just "cold air". If that's all it was, people would be running around with tanks of compressed air and injecting that into their cylinders.

Yeah that's what I was saying, just with less words

Nitrous oxide is Boost and Natural Aspiration. You're just burning more air and more fuel. It does not change the way the car aspirates.

That's debatable. All "boost" (Turbo/Supercharger) does is force more oxygen into the cylinders. That's what Nitrous does, it adds more oxygen into the cylinders. Both add to the amount of oxygen the engine has in it's cylinders compared to "normal" operation. To me, that is changing the way the engine aspirates.
