Jaystyle, good point. The Fda PowerPoint shows 2 out of 4 simple solvent having pretty
good results with physical manipulation and extended room temperature extraction. Plus the fact that the scraping technique being discussed here (pedegg or foot file) created ALOT more surface area than purdue's milling technique. Also jaystyle, notice that simple solvent 3 is missing from the moderate extraction slide, and in the simple extraction slides solvent 3 had the best results. Not by much, but still the best. Now, what would be the reason for doing that? Only thing I
could come up with is it didn't helps to make their abuse resistant claim so they deleted it.
