Anthropologist Rafael Karsten's account of a Jívaro victory feast describes the natéma ceremony, in which the vision-inducing drink made from Banisteria caapi and tobacco is prepared ritually and drunk communally. The passage covers preparation, the emetic effect, and beliefs that the visions foretell prosperity.

A 1923 doctoral thesis reporting Fischer Cárdenas's isolation of the yagé alkaloid that Rafael Zerda Bayón had named telepathine (telepatina) decades earlier without isolating it. Seven case reports detail effects on human subjects, including the author's self-experiment, describing vivid dreams, visual hallucinations, and euphoria at low doses, followed by a systematic summary of physiological action.

The Montana Supreme Court reverses a Crow man's peyote conviction, finding the state failed to establish jurisdiction over an offense on the Crow Reservation.

A New Approach

Osmond and Smythies argue that schizophrenia involves a naturally occurring adrenaline derivative chemically close to mescaline. Hosted here is a fair-use excerpt: their case that mescaline intoxication reproduces the symptoms of acute schizophrenia, the biochemical note on how a disorder of adrenaline's transmethylation could form such a compound, and their resulting hypothesis and discussion.

Rinkel and colleagues at Boston Psychopathic Hospital administered microgram doses of LSD tartrate to normal volunteers and schizophrenic, depressive, and paranoid patients. They reported the drug reliably produced thought disorder, hallucination, and depersonalization resembling clinical schizophrenia.

I. Effects in Former Morphine Addicts and Development of Tolerance During Chronic Intoxication

Harris Isbell and colleagues at the NIMH Addiction Research Center in Lexington, Kentucky, gave LSD daily for up to eighty-five days to former morphine addicts to measure tolerance and compare effects to psychosis. They found rapid tolerance to both physiological and mental effects, which disappeared upon discontinuation.

Osmond surveyed psychotomimetic agents and proposed new terminologies, settling on "psychedelic, mind-manifesting" as his choice. This paper put the word into circulation among psychiatrists, coining the term still used today.

Burdick (1908–1992) presiding. He read a long prepared statement describing his visionary experience of 1948 and his use of peyote, mescaline, LSD, and ayahuasca, then argued from newspaper coverage and the medical literature that LSD's dangers had been exaggerated and that research should be expanded. The record hosts the full printed text, pp. 487–509, including his questioning by Burdick and Jacob K. Javits (1904–1986), his list of proposed research topics (Exhibit No. 76), and the references he put into the record.

Lisa Bieberman's December 1970 bulletin explains the Comprehensive Drug Abuse Prevention and Control Act, signed on October 27, 1970, which placed LSD and other psychedelics in Schedule I. She criticizes its penalties, its "continuing criminal enterprise" and "dangerous special drug offender" provisions, and its no-knock searches, then argues against the claim that drug-induced religious experience is "unnatural."

Lisa Bieberman's October 1970 bulletin reviews the two studies then available on whether heavy LSD use damages the brain: Sidney Cohen and Allen Edwards's 1968 neuropsychological tests of thirty users, and William McGlothlin's 1969 attempt to replicate them. Because their results disagree, she concludes there is no evidence of general brain damage. The issue also prints a social worker's letter about how taking LSD changed his work with drug-using teenagers.

Art Kleps's chapter on running an LSD session from The Boo Hoo Bible (1971), the Neo-American Church catechism and handbook.

Lisa Bieberman's February 1971 bulletin responds to news that the Black Panthers in Algeria had put the escaped Timothy Leary under house arrest. It prints a memo from Humphry Osmond recalling how he and Aldous Huxley met Leary in 1960 and later came to distrust his missionary zeal, followed by Bieberman's own memories of Leary at Harvard and a critique of press claims that LSD had ruined his mind.
