alexander and anne shulgin are the chris columbus and the queen isabella of the mind. the book is split into a large scientific glossary, which spans some 400 pages, and a love story, of similar length, told through the medium of psychoactive drug experiences which they shared over the course of many years. the content is truly awe-inspiring at times (i guarantee you'll want to take some if not all the compounds they test) yet it becomes a little tedious in the midriff of anne's section. that said, i'm not a huge romantic. the magnificent glossary provides information on the synthesis, dosage and predicted responses to the several hundred compounds they have discovered or simply enjoyed. however this section can only considered as a reference. a highly recommended read both for those intruiged and disgusted by psychedelic drug culture.
