Yeah the poster above me is right. Changa is not acacia resin per say, as that link in the original post suggests. Its simply caapi/various other plant materials which has been infused with extracted dmt. (dmt is extracted normally and prior to actual crystalization, plant matter is added to the solvent+dmt. the solvent is left to evaporate which leaves you with the lovely smokable herb mix) As changa has originated in australia.. and we get our dmt from acacia, there is the misrepresentation of it being resin i suppose. Your not getting enough dmt into you, be it from simply not smoking enough.. or the changa being weak. The caapi/other maoi's are not so much essential as simply enhancers to the experience... something like changa being made with parsley will still work fine, just wont be as good.
