I've read other material by Michael Valentine Smith (free PDF articles that he's published online) and the information he presents is a mixed bag. Some information is accurate but there also seems to be an equal amount of erroneous data (for the novice psychedelic researcher this will prove frustrating!) Complicating matters further is the lack of evidential references to support his claims. An excellent scientific article written on the topic of psychedelics (with plenty of references but no how-to's to make the drugs) is "Hallucinogens" by David E. Nichols ([...])
If you want to know how to synthesize stuff buy or download (you can find torrents for this) PiHKAL and TiHKAL or check [...]. Best of luck on all future endeavors to all psychonauts around the world :)
