How do you extract mescaline out of San pedro cactus?

if you take the time to read.. you'll find your answers... look in the wiki also

Sorry to laugh, but really?

You shouldn't extract mescaline. It is probably illegal to do so. But, just google "extract mescaline." It's not much different from extracting caffeine.

What form do you want the end product to be? How pure? How much time do you want to spend extracting? What solvents, acids, and bases are available to you? Do you have a rice cooker, glassware, a food dehydrator? Sorry, Eye won't provide many answers. You must have so many questions, so read.

i was told that the thin, dark green section of the cactus right underneath the skin was the only stuff you wanted and the rest should be discarded. I have seen reports about people peeling the skin off but using everything else, including the light green portion of the plant so i would like to know as well

You can extract the whole cactus if you want, no need to clean up and separate the skin. One can just cut it in pieces, spines and all included, and boil that, doing an A/B

trashcan, please, before asking questions you should check the Nexus Wiki as most answers will be there. Also just searching the forum, or using threads such as https://www.dmt-nexus.me...posts&t=149&p=59 if is a small simple question, otherwise you'll just clutter up the forum and give the impression that you're not doing your part in researching. This is meant as no offense but as constructive criticism, hope you can understand it
