Since the moratorium on LSD in the mid-sixties, large gaps in research have left important questions unanswered. Although the doses of street LSD are very low (20-75 ugs.) in comparison to the dangerously high doses of the sixties (250-750 ugs.), a problem of misuse still remains.

Until controlled clinical studies are resumed using low dosages, most of what we know today will remain based on reports dating from the early sixties and fifties.

LSD-25 & Tryptamine Syntheses gives the reader an inside look into the chemistry and construction of these molecules. It is important for those in the legal and medical professions, law enforcement, and students of the neurosciences to have a greater understanding of these psychoactives.
