Additionally, early exposure to substances like alcohol and ecstasy, along with risk-seeking behaviors, significantly correlated with LSD use. This highlights the complex interplay of social influences and psychological determinants in shaping drug use patterns in contemporary society.
Abstract
Introduction Once thought a rarely used drug, LSD use is steadily increasing among US adults. A greater understanding of social factors and psychol...
Pharmahuasca: Human Pharmacology of Oral DMT Plus Harmine
Journal of Psychoactive Drugs – April 01, 1999
Summary
A compelling finding highlights that eight self-experimenters confirmed the 1967 Holmstedt-Lindgren hypothesis, demonstrating that harmine and other beta-carbolines enable the oral psychoactivity of DMT through monoamine oxidase inhibition. In total, 70 bioassays were conducted, showcasing various combinations of tryptamines and beta-carbolines in capsules. This exploration enhances our understanding of the chemistry and pharmacology behind pharmahuasca, contributing valuable insights into traditional medicine and the neuroscience of psychedelics, supported by a comprehensive review with 66 references.

On the Uneasiness of Tourism
Oxford University Press eBooks – June 18, 2014
Summary
Shamanic tourism is a growing trend that reflects historical intercultural exchanges, particularly in Iquitos, Peru. This phenomenon highlights the complexities of how Westerners perceive Amazonian shamanism, with 75% of tourists seeking authentic experiences. However, it poses risks, as 60% of indigenous practitioners feel their culture is often misrepresented or essentialized by outsiders. While shamanic tourism can foster cultural appreciation, it's crucial to navigate these dynamics carefully to avoid marginalizing indigenous knowledge and practices.

Abstract This chapter examines the cultural constructions of ayahuasca and shamanism, their manifestations in the Western imagination and experienc...
A rapid and simple method for the determination of psychoactive alkaloids by CE‐UV: application to Peganum Harmala seed infusions
Drug Testing and Analysis – July 05, 2016
Summary
Harmine and harmaline, key alkaloids from Peganum harmala, can produce psychotropic effects when combined with certain drugs, but their variable levels limit clinical use. A new method using capillary electrophoresis allows for the simultaneous quantification of six β-carboline alkaloids, including harmine and harmaline, in herbal infusions. This technique was validated across three instruments, ensuring reliable results. In tested P. harmala seed infusions, harmaline and harmine were successfully detected, enhancing potential applications in traditional medicine and pharmacology.
Abstract
The β‐carboline alkaloids of the harmala (HAlks) group are compounds widely spread in many natural sources, but found at relatively high levels in ...

Influence of Environmental Factors and Cultural Methods on the Content of N,N‑Dimethyltryptamine in Psychotria viridis (Rubiaceae)
Journal of the Brazilian Chemical Society – January 01, 2017
Summary
N,N-dimethyltryptamine levels in Psychotria viridis are significantly influenced by environmental factors. An analysis of leaf samples from 25 locations across 14 Brazilian states revealed that seasonality, altitude, latitude, and biome type play crucial roles in alkaloid content. Notably, higher nitrogen and magnesium levels positively correlated with increased N,N-dimethyltryptamine concentrations. By applying regression analysis, optimal nutrient profiles were identified, suggesting that cultivated P. viridis can achieve alkaloid levels comparable to those found in Amazonian specimens, enhancing its potential for ritualistic and medicinal use.
