TIHKAL: The Continuation

TiHKAL: The Continuation is the sequel to PiHKAL: A Chemical Love Story. TiHKAL is written about a family of psychoactive drugs known as tryptamines with TiHKAL being an acronym for "Tryptamines I Have Known and Loved”. Like its predecessor, it is divided into two parts. The first part of the book begins with the story of Alice and Shura, a fictionalized autobiography, which picks up where the similar section of PiHKAL left off. The second part of TiHKAL is “The Chemistry Continues”. It is a detailed manual for 55 psychedelic compounds (many discovered by Alexander Shulgin).
