Ok, so i had this high-dea last night when hitting a vape that was turned up a bit too high. I got super dense vapor for a second, then the dirty smoke from combustion. So I was thinking, if there was some way of removing oxygen from the air path, couldn't we then vape at temps that would normally cause combustion? I'm sure removing the oxygen is a non-trivial step, but assuming we somehow replaced it with something inert (I'm thinking nitrogen just off the top of my head), would that mean we could then crank our vape up super high, and do something equivalent to dabbing (that is, use a really high temp to very quickly vaporize most/all of the compounds we are after) I mean, for fire, we need heat (the vape), Fuel (the MJ) and oxygen (from the air) right? Or am I missing something and can combustion occur without oxygen? I could see potential benefits in that -there's a potential for vaping off compounds that may not boil until above the regular combustion point (not sure if there are any, but I'm sure I've seen charts showing MJ compounds going pretty damn high with their boiling points -potential massive clouds for cloud chasers like myself (massive in the sense of 1-2 thick, dense hits and the load is done, not drawing it out over 5-6-7 hits... I know vapes like the cloud can finish a bowl in 1 hit, but my cloud usually gives me at least 3-4 good rips before the vapor starts thinning out...) -possible improvement to high-temp taste as there'd be no oxidation happening? (pretty sure I'm wrong about that one, but it's a discussion point ) I can also see some potential negatives in that -there's a potential for oxygen deprivation - I would think that 1 hit wouldn't be long enough to cause any serious risk, but I'm no expert on it, and I know I've gotten a bit light headed when playing around with inhaling helium from party balloons, so maybe its a similar thing? -not particularly useful for low temp vapers, though if the oxidation thing does affect taste, it may still help here? -Potential for the load to instantly burst into flames if it's heated to above the point of combustion, and oxygen somehow gets into the system -at high enough temps, perhaps some of the combustion nasties we're trying to avoid will be produced anyway, regardless of whether actual combustion occurred? I know we've got some members about who will know way more about applying the science to this idea than myself, so whaddoya guys think?
