You two are both right. You will have to agree to disagree.
SWIM has eaten San Pedro raw many times in the past and tripped without getting the slightest bit of nausea. So I agree with Coatl there. Some people never get nausea from San Pedro.
Peyote is more prone to producing nausea in sensitive people than San Pedro is. Some people also do not get nausea from Peyote. Some people actually enjoy chewing Peyote buttons. It's like wine, you can acquire a taste for it.
It's all about person taste and personal body chemistry. SWIM doesn't really like eating such a large amount of cactus, but the main reason he prefers an extract is that the dose can be accurately measured out. For SWIM, the effects of the cactus are the same as the effects of the vinegar/orange oil extract. Neither one causes him nausea. However, that's not the case for some other people. Some people get nausea from the cactus only, and others get nausea from both.
Pure mescaline also causes nausea in some people. SWIM doesn't get nausea from pure mescaline.
To really make a mess of things, SOME people get MORE nausea from pure mescaline than from the cactus! It's all about personal body chemistry. It all depends on what in the cactus makes you nauseated. There are many alkaloids present. You could be sensitive to any one of them. If you're not sensitive to mescaline, then a pure mescaline extract would be the best for you, but if you're sensitive to mescaline, then a full alkaloid extract or the raw cactus might be a better experience.
The San Pedro cactus contains quite a bit of alkaloids. SWIM has separated the mescaline from the other alkaloids and found that the non-mescaline alkaloids are psychedelic and have other effects as well. One of them is sedating, one makes you feel numb, one is visual, etc., so anyone of those could be causing nausea or not. Heck, it could be the plant fibers causing nausea in some people, in which case an extract might not.
Everyone is different.
Coatl, I do have to side with Jorkest in that making a vinegar/orange oil extract is really easy. I'm not exaggerating here. I'm a cook. I make breads, cakes, pizzas, you name it, I can make it from scratch without a recipe. The work going into making bread is far more than the work going into extracting mescaline from cactus using vinegar and orange oil. You mix dry ground cactus with water and lime, then you mix in orange oil, you pour off the orange oil through a coffee filter. You mix vinegar with the orange oil. Then use a gravy separator to remove the vinegar from the oil. Then you evaporate the vinegar and you are done. It's very easy. Mix, pour off and filter, mix, separate, and evaporate. That's 5 easy steps. It's so simple.
Compare that to baking bread where you mix the dry ingredients, add oil, water, knead the dough, let it rise, knead it again, let it rise again, put it in the oven, watch it periodically to make sure it cooks just right, when it just starts getting a little brown it's done. When making bread you need to time everything. You can't let it rise too long or you ruin the bread, if you don't let it rise enough you ruin the bread, if you cook it too long you ruin the bread, etc. It's much more complicated than extracting mescaline.
You may remember me as 69Ron. I was suspended years ago for selling bunk products under false pretenses. I try to sneak back from time to time under different names, but unfortunately, the moderators of the DMT-Nexus are infinitely smarter than I am.
If you see me at the waterpark, please say hello. I'll be the delusional 50 something in the American flag Speedo, oiling up his monster guns while responding to imaginary requests for selfies from invisible teenage girls.
