There are many different drug recipes in print. Unfortunately, these are usually written by authors who make some unwarranted assumptions about their readership not everyone interested in psychedelic extraction procedures is necessarily familiar with the language and principles of organic chemistry. In such cases, one is blindly following instructions that one does not fully understand. This is the antithesis of alchemy and an almost guaranteed way to make mistakes. Although complex laboratory procedures should never be attempted by amateurs (the synthesis of LSD, for example), there are many simple recipes that can be safely performed by any reasonably patient and intelligent person.
