Feedback Wanted: Extraction Of Psilocybin/psilocin With Acetic Acid

A friend of mine ask me to post this for him due to his computer crash. There was a good study (old) done on extraction of Psilocybin/Psilocin and posted at http://www.erowid.org/plants/mushrooms/mushrooms_journal1.shtml

It appears Acetic acid is a good/safer second choice in the extraction even though yield will be sightly less but safer and more natural than methanol. He is willing to give up some yield for a more natural/safer extraction process and considering there is not a major lose of Psilocybin and a gain of Psilocin.

QUESTIONS:

1. Is this Tec still a good one or is there a newer/better one?
2. Would you dry the Acetic acid almost completely and then put the left overs in Everclear and store in the freezer w/o O2 present?
3. Would a Soxhlet device be a good choice for extraction?
4. Can a Soxhlet device be used for extracting DMT and also Mescaline using safe materials?
5. Would a used CELL DISRUPTOR be a good choice in making material more exposed to the acid?
6. Is there any other lab equipment needed?

Thanks for any replies
