make changa using 99% IPA or Dry Acetone, heres how i would make it..
50 mg mullein
5 mg harmine
45 mg DMT
Dissolve harmine and DMT in minimal amount of solvent and throw in the mullein. Let dry. Shouldnt take long. Make sure its completely dry (doesnt smell like solvent at all)..
Smoke it in a normal piece, in one go. I find the best way is to be veery gentle, just tap it with the fire, to get it going, and then slowwwwly draw every little leaf, imagine lighting the corner and slooowly the fire creeping along like dominoes across the bowl. The slower the better, take multiple hits if necessary. Hold it!
Good luck, BTW harmine will GREATLY effect the experience. It lasts longer, comes on much slower and in waves, i find it to be much more ayahuasca like..
Its beautiful.
