Actually N2O, not NO2. It is necessary to mix at least 15% oxygen with this,
as hypoxia will otherwise occur. Of course, a short sniff of pure N2O will
not create severe hypoxia, and as long as someone takes the pure N2O away
in time, there should not be any brain damage. Possible (individual) 
euphoric effects do not require simultaneous hypoxia.
