The smoke is actually the nitrogen AND water vapor. Nitrogen has a low melting point, and when it is put under pressure and very low temerature, it will become a liquid. When that liquid hits normal air, it rapidly absorbs the heat around it causing "smoke", which is the nitrogen turning into a gas again, and some water vapor condensing from the low temperature.
