The Commemorative Edition of Pihkal and Tihkal

PiHKAL is the fictionalized autobiographical account of Sasha and Ann Shulgin's research and romance, exploring altered state experiences in the context of intimacy. It describes a wide variety of phenethylamines, their dosage, and their effects. The second volume, TiHKAL, uses the same format as Pihkal to describe the effects of a range of tryptamines, and continues the Shulgin's chemical love story. It also includes appendices that relate to cactus alkaloids, natural beta-carbolines, and drug law.

In this edition, each book has been split into two to make a collection of four books. The set, housed in a beautiful slipcase, includes:

PiHKAL: The Love Story

PiHKAL: The Chemical Story

TiHKAL: The Story Continues

TiHKAL: The Chemistry Continues
