TiHKAL
TiHKAL: The Continuation, also known as Tryptamines I Have Known and Loved, is a 1997 book written by Alexander Shulgin and Ann Shulgin. It is about a family of psychoactive drugs known as tryptamines, which includes psychedelics, other hallucinogens, and entactogens. The book has two halves, and the second part of the book contains detailed entries on 55tryptamines. TiHKAL is a sequel to PiHKAL: A Chemical Love Story .
Content
TiHKAL, much like its predecessor PiHKAL, is divided into two parts. The first part, for which all rights are reserved, begins with a fictionalized autobiography, picking up where the similar section of PiHKAL left off; it then continues with a collection of essays on topics ranging from psychotherapy and the Jungian mind to the prevalence of DMT in nature, ayahuasca and the war on drugs.The second part of TiHKAL, which may be conditionally distributed for non-commercial reproduction, is a detailed synthesis manual for 55tryptamines, including their chemical structures, doses, durations, and commentary. It includes entries on compounds including simple tryptamines like dimethyltryptamine, psilocin, and 5-MeO-DMT, α-alkyltryptamines like α-methyltryptamine, β-carbolines or harmala alkaloids like harmaline, the iboga alkaloid ibogaine, and lysergamides like LSD. Whereas PiHKAL had 179entries on phenethylamines, TiHKAL has only 55entries. Shulgin has made the second part freely available on Erowid while the first part is available only in the printed text.
Members of Shulgin's research who contributed to the experience reports included Shulgin himself, Ann Shulgin, Myron Stolaroff, and Jean Stolaroff, among others.
