I would argue and say that changa or enhanced leaf does burn quite the same, depending on the ratio of DMT to leaf mix.
I've found that on my 2:1 spice to herb enhanced leaf, it is quite easy for the spice to flame up, and when that happens I get the same horrid taste of burnt freebase spice.
I usually use 1:1 and cover the dose in peppermint which keeps some of the direct heat off the spice. Lightly cherry and milk that bad boy up, one 40 mg rip of 1:1 and it's sayonara reality.
