Toast the seeds in the oven for like 15-20 minutes or whatever..you should smell some unwanted stuff vaping away from the seeds. Bufotenine has a high boiling point so it will not vape away unless you taost them too high.
Then crush the seeds up into a powder, mix in sodium carbonate and some water to make a paste..mix that around for a minute or so and then let it dry.
Once dry do 3 pulls on that with iso or acetone..
Collect and filter each alcohol pull and combine..and then evaporate that onto either caapi leaf or some other innert smoking material. Do not just evaporate this stuff all the way down without evaporating it onto some leaf mix. It will be an oily goo that makes a mess.
Long live the unwoke.
