Just a small idea here, when _Trip_ came up with the idea to directly salt out Bufotenin with Benzoic Acid and use it straight away I was arguing that the salt might still contain some contamination, which is removed by toluene. Luckily you still tried it and got those super nice bright crystals. Just based on the look I was thinking that looks definetly not defiled with any other stuff, which would go straight against having any more gunk inside.

Check what I meant on the picture on the right.

Furthermore I would even have no idea what this powder could be in terms of contamination. It is also coming from the salting step, so it has a N in its formula, most certainly being an Alkaloid just like Bufotenin. But it would be even more polar and not dissolving in boiling Xylene. That would be reaaaally weird and unusual. On top of that, what alkaloid would that be ??? I mean I dont know too many unusual ones, but the only more polar are stuff like Bufotenidin (= NMe3+ instead of NMe2) and this stuff would be only present in traces. Actually at 140 °C you also degrade Bufotenin already slowly, but then it will form a dark-brown layer burned into the glass and not fine powder. So this all made 0 sense so I was thinking about this again.

Now I think I came to a logical solution, but of course cannot prove just now. And if this would be right, then I was telling crap that there would be any contamination left behind in the final product.

Idea is:

In this TEK the freebasing of the Alkaloid(Bufotenin?)-Fumarates is done by adding them in water to another water + saturated Na2CO3. Then the freebase is instantly created, forming a goo, which will collect to a ball. This formation is pretty fast so it will be voluminous, incorporating lots of the liquid around it. This liquid is water and is boiled off when doing the Xylene-REX at 140 °C. So I believed nothing would stay behind. BUT the water is saturated with Na2CO3. Of course this does not evaporate. And while the Freebase is constantly travelling into the boiling Xylene, it will start revealing the incorporated Na2CO3 again. And the more the Na2CO3 is getting uncovered, it will form more and more a solid powder. Voila! Now why is this powder brown as seen in the picture? The Bufotenin that partially degrades already at 140 °C will burn into the Na2CO3 instead of into the glass. This will give it the brown shape, yet being free-flowing as seen in the picture.

So I have no proof for this, but in my mind it makes 100 % sense and therefore it that would be true, you could directly salt out Bufotenin and use it. People who just want to eat it could directly use stop at the end of step #4. And people who want to smoke it could simply salt it out with Benzoic Acid - without boiling Xylene stuff. Pretty much the TEK that you already wrote at the wiki! And Woolmer may have simiply gotten not that nice crystals, because of no Naphtha defat, that would have removed other trace Alkaloids, that now co-precipitated and disrupted formation of the nice bright needles and stars. So long story short, no proof for this but I believe my argument for not-skipping that toluene REX was pointless and your TEKs should might likely give same purity with way less steps.
