Nitrous oxide is N2O.
It is also possible that the damage is a direct effect of
nitrous itself. Nitrous destroys vitamin B12, which in extreme cases
can lead to peripheral demyelination and consequent motor impairment.
I don't have any information on just how good it is at this, though,
or how effective pre- or post- dosage supplementation is at preventing
damage. Check out the abstract at
As far as hypoxia goes, this is a problem for people doing
whippets out of balloons and the already-impaired who try to suck
right out of the tank (fortunately, the frostbite usually gets to them
first). It seems that a nitrous/oxygen mix should be safe, but this is
difficult to obtain outside a dentist's office. Chalk up another one
