I have had no effects from huffing air duster? Please anwer? - dizziness from vibrating toothbrush

In the 15th and between me and my friend, we blew through a field of air duster. I still had no effect, and since then have heard most people go after a few shots, but the blowing up half of the can and nothing happens, except the extreme dizziness, drowsiness, I stumble, and I felt like vibrations.

It was really strange, but it felt good at the moment.

Since I did not faint / the first time that the inhalation of little effect when I use the same amount?
