Welcome to the Nexus!

Since this is an intro essay, would you mind telling us a bit more about yourself? You say you have done successful extractions, what kind of extraction method do you usually go for?  Also you mention smoking dmt, what is your method of smoking?  Did you try or are interested in trying oral dmt/ayahuasca? What about other psychedelics?

Regarding the purity issues, yeah Shayku is right I think that this is pretty self evident.  And also, do notice that certain impurities could potentially be beneficial depending on smoking method by protecting the DMT from combustion (at least thats one of the educated guesses regarding jungle spice's differences of effects)

Btw, check this thread about chemical analysis of DMT from different extractions, its relevant to this discussion:
