TIHKAL: The Continuation is a 1997 book written by Alexander Shulgin and Ann Shulgin about a family of psychoactive drugs known as tryptamines. TIHKAL is an acronym that stands for "Tryptamines I Have Known and Loved". The book is a sequel to PIHKAL: A Chemical Love Story.

TIHKAL is divided into two parts. The first part, for which all rights are reserved, begins with a fictionalized autobiography and 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 55 psychedelic compounds (many discovered by Alexander Shulgin himself), including their chemical structures, dosage recommendations, and qualitative comments.
