extracting mescaline from dried san pedro skins

hi there is extracting mescaline from dried san pedro skins. is it actually worth it? if you buy the right skins im guessing it would work for a mescaline extract, im very familiar with the dmt extract but im sceptical about cactus skin.

 

The outer skin dosn't have anything you want, that is the layer that causes nausa. most of the mescaline is in the layer under

 

Its the xylem youre after, the green layer between the white core and the skin. There are a variety of extractions to do, in varying degrees of difficulty. My friend had a bunch of San Pedro and was planning on doing a simple isopropyl alcohol extraction, but he let it all rot anyways. Ive never done a san pedro extraction, but I would reccomend at least doing a crude chemical extraction. that way youll end up with a powder, which is much easier to deal with.

 

I use the whole catcus because of waste not. never once have i experienced nausea more in on part of the plant then another. in fact i have never been nauseas from trichocereus. only way i can see sombody throwing up off of it is the taste.
