What exactly does this do. Does it actually have effects, and if it does...how would you classify the effect? Carbogen?
its a gas mixture of oxygen and carbon dioxide...the oxygen gets you buzzed and the carbon dioxide makes you think you're sufficating [because your lungs say "sufficating" at the presence of carbon dioxide, not lack of oxygen]
so does it feel like your dying but you don't actually die? or is it pleasant? is it even a drug, why would someone do it?
