Cover of PiHKAL: A Chemical Love Story, by Alexander & Ann Shulgin. Cover art by Pamela EngebretsonPiHKAL • info is a visual index and map of “PiHKAL: A Chemical Love Story,” by Alexander & Ann Shulgin. PiHKAL is the extraordinary record of the authors’ years exploring the chemistry and transformative power of psychedelic drugs, and phenethylamines in particular.

PiHKAL (the book) covers a lot of ground. There are detailed reports on 179 substances, and mention of perhaps 150 more. Still other phenethylamines, not discussed in the book, are known or are suspected to have psychedelic potential. PiHKAL • info is my attempt to map out the terrain.
