Hallucinogens are widely used, both by drug abusers and by peoples of traditional cultures who ingest these substances for religious or healing purposes. However, the long-term residual psychological and cognitive effects of hallucinogens remain poorly understood. We recruited three groups of Navajo Native Americans, age 18-45: 1) 61 Native American Church members who regularly ingested peyote,...
Two archaeological specimens of peyote buttons, i.e. dried tops of the cactus Lophophora williamsii (Lem.) Coulter, from the collection of the Witte Museum in San Antonio, was subjected to radiocarbon dating and alkaloid analysis. The samples were presumably found in Shumla Cave No. 5 on the Rio Grande, Texas. Radiocarbon dating shows that the calibrated 14C age of the weighted mean of the two...
Dipeptidyl peptidase IV (DPP IV) is a ubiquitous membrane-bound enzyme that cleaves the two N-terminal amino acids from peptides with a proline or alanine residue in the second position from the amino end. Potential substrates for DPP IV include several neuropeptides, suggesting a role for DPP IV in neurological processes. We have developed a potent DPP IV inhibitor (IC50 = 30 nM),...

Peyote is one of the best-known plant sources for a psychedelic experience. This small cactus is also associated in the popular mind with North American Indians and Hippies. Although its ritual use is thought to be over 7,000 years old (Furst 1989, cited in Schaefer 1996: 141), its use by Indians of the Native American Church (NAC) is less than 100 years old. The peyote button is the essential...
[reaction: see text] A tetrahydrobis(benzofuran) mescaline analogue has been prepared in six steps and 38% overall yield from (4'-O-methyl)methyl gallate. The key step in this synthesis is a tandem cyclization reaction via directed C[bond]H activation followed by olefin insertion.
The Native American Church is examined as an illustrative example in the political anthropology of consciousness. Specific attention is paid to the Supreme Court's ignoring of accepted research on this tradition and its sacrament, Peyote, in the case of Employment Division of Oregon v. Smith. An anthropological reaction to the Smith decision is constructed, focusing on ethnographic findings...
Of the three religious healing traditions that coexist within the contemporary Navajo health care system, the Native American Church (NAC) and Pentecostal Christianity are more actively involved in the treatment of alcohol and substance abuse than is Traditional Navajo healing. This article examines these two more recent healing traditions as religious responses to the contemporary Navajo...
Behavioural effects of two experimental neurotoxins, mescaline and DSP-4 (N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine), on retention of spatial orientation were studied in the T - maze. The stereotaxic administration of both neurotoxins into the selected brain structures was chosen to reveal this effect. The intensity and time course of the neurotoxic effect were dependent on the brain area...
The psychological, neuropsychological, and neurometabolic effects of the hallucinogenic agent mescaline were investigated in 12 normal male volunteers. Between 3 1/2 and 4 hours after drug intake, mescaline produced an acute psychotomimetic state, as measured by the BPRS and PDS-P. The APZ questionnaire revealed the specific effects of mescaline in the visual system. Neuropsychological effects...
