Just to clarify, I only used the 75% Everclear during the complexation process...not during the salvinorin extraction process. 

I used cold-to-luke warm acetone for the pulls (started at 20F), then naphtha several times to clean.  I did not use additional cleaning steps with IPA to get a pure extract...I just left it at that somewhat crude phase which I eventually bioassayed.

For the extraction process, I basically followed the first half of Gibran's method from his pinned thread here.

I'm guessing you've extracted salvinorin previously, but if not, you can avoid the black tar mess I created on my most recent extraction if you use colder acetone and/or shorter pulls.  It will save you a few days of extra cleaning that I had to go through.  When I did my last one, I realized AFTER that I could have set my freezer much colder :? . 

Obviously, I'm interested in what you come up with!
