Welcome to 15 years ago!
Guess what, kids also do it with butane (gaseous lighter fluid), paint thinner, gasoline, and pretty much any other household chemical that doesn't make you choke.... it's laughing gas for people who aren't capable of getting laughing gas.
Hell, when I was a kid I even did some of the above.. not telling which one though

I didn't die.. neither did anyone I knew.
Do you believe that smoking pot leads to heroin addiction too?
