I found this page on the extraction of various psychoactive chemicals, but the author kinda doubts his knowledge.
So i decided to ask you guys if his article is valid.

Heres what he said that made me think twice before carrying out the procedures...

Disclaimer: I am only combining things that I have read here and there. These methods are rather crude, so feel free to refine them. I am trying to avoid any methods (apart from the THC extraction) involving the heating of non-polar solvents; I will allow someone with experience in chemistry to elaborate in that area.

There THC extraction is absolute shit, do you really want to be smoking weed and acetone? Please, half of the stuff there is copy pasted from other teks.
