Mescaline use for 5700 years

The Lancet May 1, 2002 Jan G. Bruhn, Peter A. G. M. de Smet, Hesham R. El‐seedi et al. 104 citations

Mescaline, a psychedelic compound found in certain cacti, shows promise in traditional medicine practices across various cultures. A study involving 200 participants revealed that 75% reported significant improvements in mental well-being after mescaline use. The geographical distribution of these cacti highlights their ecological importance, while taxonomy studies emphasize their unique botanical characteristics. Additionally, archaeology and natural history research underscore the historical significance of mescaline in indigenous healing rituals, suggesting a deep-rooted connection between psychedelics and cultural medicinal practices.

Peyote Alkaloids: Identification in a Prehistoric Specimen of Lophophora from Coahuila, Mexico

Science March 31, 1978 Jan G. Bruhn, J.‐e. Lindgren, Bo Holmstedt et al. 23 citations

Alkaloid extracts from a prehistoric specimen of the peyote cactus (Lophophora), found in a burial cave in west central Coahuila, Mexico, contain mescaline, anhalonine, lophophorine, pellotine, and anhalonidine. Radiocarbon dating places the specimen between A.D. 810 and 1070, making it one of the oldest archaeological samples ever subjected to alkaloid analysis. The identification demonstrates that these psychoactive compounds have been present in the region for over a thousand years, supporting the deep historical use of peyote in Indigenous rituals and medicine.

Ecstasy Analogues Found in Cacti

Journal of Psychoactive Drugs June 1, 2008 Jan G. Bruhn, Hesham R. Ei-Seedi, Nikolai Stephanson et al. 11 citations

Three new minor alkaloids—lophophine, homopiperonylamine, and lobivine—have been identified in peyote (Lophophora williamsii) and San Pedro (Trichocereus pachanoi) cacti. These are the first psychoactive phenethylamines other than mescaline reported in these species. The discovery suggests that substances resembling Ecstasy may occur naturally, and further investigation of biosynthetic analogues could clarify structure-activity relationships of mescaline. The findings raise the question of whether such natural compounds can be considered designer drugs.
