I tried this a few years ago with powdered yopo seeds and baking soda packed into a flimsy tissue paper that would dissolve. unfortunately I didn't notice any trippy effects. I guess the dmt content of those seeds were not that high. Neither was I willing to use CaO instead of NaHCO3.. I think you'll understand why
Apart from social taboos is makes a lot sense of using the mucus mebrane of the lower intestine: supposedly no MAO and efficient uptake .
when I get my hands on some dmt crytals again, some experimentation could be interesting
Oh, and strong bases like NaOH or CaO can be left out... the tryptamine is already in its freebase form. So no pain in the butt from that part.
...Don't be anal about it
