After an IPA re crystallization, because of a terrible naphtha smell that wouldnt go away, ive smoked a bit of this new stuff thats been air drying for like a week now, it smells kind of off, but i thought ide give it a try, to my supprise, my mouth burned afterwards, and the smoke was super harsh. Im sure its the IPA. Im thinking of re dissolving in naphtha, and seeing if i can maybe get a break this time. I think the gods dont want me to break through just yet

If your dmt is very brown it could be plant material, which is harsh to smoke. But I doubt that since you reX'd
There is also the possibility that you burned the dmt

I bet my shoes you are burning it. What is you smoking device and technique ?

Just put it in a glass bottle and heated it. :0

yes you are burning it my friend you need better device. Make your self the machine its very easy to do, cheap and very effective.
