I would like to more about this as well..
I do know for sure from many personal experiments with the same batch of seeds that untoasted seeds have way more side effects..and that toasted but unextracted seeds have more side effects than the extracted resin..
Now the last batch I extracted and made into changa..I used all seeds that I had already extracted from..and some of them were from my first 2 batches i extracted..and I had only toasted those ones once..and not very thoroughly..
Now this batch has alot more side effects than my previous 3 or 4 batches..so either less toasting is leaving more toxins behind..or I am pulling a higher ratio of those toxins compared to bufotenine due to it being a second extraction on the seeds...I think one of those 2.
I know that the extra side effects of this batch is not from simply more bufotenine being extracted..becasue if it was that, than I would be getting a high dose of bufotenine..which I am not..just more side effects prior to the real trip..
I cannot even smoke enough of the toasted and freebased seeds to have real visions becasue of the side effects..but when I toast the seeds thorouhly, 2 or 3 times in the process and pull with iso..I can easily smoke enough and the side effects are minimal..mostly just some constriction at the beginning..no real heavy nausea or headache etc..
I think that there are some side effects from bufotenine..but I think it is from vasoconstriction..I think ron has even said that with his pure bufotenine there is some minor constriction at higher doses..
From what I have gotten from my experiments so far..there is 2 types of side effects that I have felt..the first one is really bad..heavy nausea and mild headache at the beginning..and it sort of lasts through half of the trip as well..thats is with just smoking prepared snuff..
With my extract(taken with harmalas) there is constriction..but it is tolerable and clears up within a few minutes and then the real trip starts to happen. If it was bufotenine causing all of the effects..than I should be getting worse effects with the extract becasue I am getting a much higher dose of bufotenine..enough to have visions..even without harmalas I get much deeper effects with the extract.
Now when I take the extract with coffee..the side effects are even less still..which again makes me think that bufotenine itself is a bit more vasoconstrictive than DMT, psilocybin etc..
Could it be that when freebased bufotenine is smoked..some of it still goes to the body and hits the seratonin receptors throughout the body, since it is so similar to seratonin..causing the physical constriction?
Long live the unwoke.
