Typical nitrous applications (aka wet systems that are not direct port) use a setup that sprays both fuel and nitrous into the intake tract, usually before the throttle body.

What happens is that fuel pools in puddles in the intake, and then gets detonated in the intake instead of in the cylinders. This usually blows the intake apart on a stock (factory) manifold.

Sometimes you get lucky and all it does is throw some fire and blow your intake pipping off, but there is a video in the vids section someplace of a early model cobra spraying his shot too soon. At low RPM, there wasn't enough suction in the intake, the fuel puddled, and it literally blew his intake apart.
