I've got her book. She speaks positively on her peyote and LSD experiences too.
Peyote is such a cute little cactus as well. Just a little dumpling loaded with 3,4,5-trimethoxyphenethylamine and about 50 related bases. Also of interest is the isoquinolines (cyclized phenethylamines) in the cactus. They definitely contribute to the psychoactivity of the cactus as a peyote trip is very different from a straight mescaline trip. Shulgin has a book coming out soon which will detail some of the isoquinolines...as of now their psychoactivity is a mystery.
And again, thank you. I will check out the new links you have posted when I am off work.
