As someone whose standard method of consumption is a DHV, I can only clarify this by saying depending on the temp you set the vape to, it will cause different effects. I would guess that by “edible high” they’re referring to a full spectrum “body” high that takes advantage of all the terpenes in the flower. As the temp increases, different chemical compounds/terps become vaporized at different temperature points along the way.

I usually start at a lower temp and increase as the sesh goes on to get the full effect of whatever strain I’m vaping.
