Considering extraction of mescaline, allot depends on what (grade) chemicals and equipment are available to you.
Perhaps go from there.
Personally i would recommend the 69ron tek using xylene as NP, and HCl for salting. I have seen good results (literally) with this method.
The raw extraction product is easy to clean with acetone and IPA.
If you insist on using vinegar for salting it is advised to do a search for the goo factor.
