I read an interesting post on another vape forum by an organic chemist, who suggested that if the herb was heated in nitrogen it would prevent oxidation, and so it should be possible to do high-temp (and thus full-spectrum) vaping without unwanted by-products of the pyrolysis.
Here's the post:

Since nitrogen (a gas) makes up 75% of the atmosphere, it's not harmful, though if you were to inhale it pure I'm sure it would make you pass out. So a convection system might be tricky, unless you have an oxygen inlet downstream of the bowl.
But with a clever bit of engineering it might be possible to rig up a conduction system with a chamber that fills with nitrogen before heating the herb, and then cools the herb (or dumps it) before the vapour is to be inhaled.
Any thoughts?
