what does NOS do to the body?

Question

as in by inhaling it froma balloon....

Answer 1

NOS is an anesthetic gas, you can breathe too much and pass out, also, since there is no free oxygen you can suffocate if you breathe only NOS. NOS has been known to cause problems in blood formation, so we don't use it with people who have severe anemias. Not a good thing to play with, it should only be used in controlled situations unless you like waking up dead or mentally damaged.
