I founfd this (http://video.google.com.au/videosearch?hl=) video on how to extract mescaline from cacti, I was curious to know if this extract produced good quality mescaline. The pictures i've seen from other ectractions of mescaline appear to be more crystaline like, not like dirt.
Also, what type of cacti is used in the video? The other ecraction i've seen use ALOT of ground up cacti, this video he only used 400g of cacti skin?
I didn't watch the whole video, as my drunk attention span is about two minutes, but the cacti was definitely a tricho, probably pachanoi, but bridgesii, and Peruvian torch are both possibilities as well.
Its got the theory in the regions of being correct, but it just looks like a shoddy job. I'd bet with a fair amount of cleaning, for example a recrystallisation from MEK, you could achieve something of nice purity, out of that mess, but I'd not want to be eating half a gram + of that stuff. I'd rather try to do it right from the start than cover up mistakes and corner cutting at the end.
