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 {{See below|{{section link||External links}}, below}}, is a detailed synthesis manual for 55 psychedelic compounds (many discovered by Alexander Shulgin himself), including their chemical structures, dosage recommendations, and qualitative comments. Shulgin has made the second part freely available on Erowid while the first part is available only in the printed text.
As with PIHKAL, the Shulgins were motivated to release the synthesis information as a way to protect the public's access to information about psychedelic compounds, a goal Alexander Shulgin has noted many times. {{cite news |first = Drake |last = Bennett |url = https://www.nytimes.com/2005/01/30/magazine/30ECSTASY.html |title = Dr. Ecstasy |work = New York Times Magazine |date = 2005-01-30 |access-date = 2006-07-08 }} Following a raid of his laboratory in 1994 by the United States DEA, {{cite web | title = DEA Raid of Shulgin's Laboratory | publisher = Erowid | date = 2004-01-08 | url = http://www.erowid.org/culture/characters/shulgin_alexander/shulgin_alexander_raid.shtml | access-date = 2006-07-08 }} Richard Meyer, spokesman for DEA's San Francisco Field Division, stated that "It is our opinion that those books [referring to the previous work, PIHKAL] are pretty much cookbooks on how to make illegal drugs. Agents tell me that in clandestine labs that they have raided, they have found copies of those books."
