Amyl nitrate is an NO (nitric Oxide) Donor ie. it is taken up in the body and releases Nitric Oxide which is a neurotransmitter and local regulator of the body.
NO generally causes vasodilation, bronchodilation, relaxation of the GI and GU tract oh, and helps in male erectile dysfunction.
So Amyl will just cause your blood vessels to dilate, increasing blood to your brain, hence the spinning feeling. Actually thinking about it it might even make it easier to go to the toilet while rolling! (relaxation of urinary sphincter)
The gay community use it to relax anal sphincters so they can insert things easier (errrrrrrrrrrmmmmmmmm!)
Um, no it cant cause brain cancer!
ohhh, and it should be used if u r taking viagra!
