Is laughing gas, and NOS the same?

lol i feel like this is a dumb question

but is the nitrous oxide dentists use the same as the nitrous oxide used in cars to increase combustion in the intake manifold?
no there not the same .. NOS has added chemicals. NOS can be lethal if in healed . I know a guy(Buddy Biship) who used to puff the NOS for the system on his drag bike .. it killed him .
its the same but racing NOS has added chemicals to prevent people from inhaling it
