Good research nullific, but nonetheless this is still an extremely dangerous thing to mess around with. On the news a kid in my city died from inhaling this in his bed, and his parents woke up the next morning to find their son dead. The chemicals in it is not what causes the "high", its the propellants in the can. And if you sprayed this shit in the wrong way frozen liquid will come out and give you frostbite in your throat/lungs etc. If you are looking for a cheap high, you'd probly we better off inhaling gas or paint or something. Just don't do this stuff.
