Taken the diverse psychological effects they exert, the main mechanism of action of hallucinogens; LSD, ibogaine, THC, PCP, MDMA, methamphetamine, mescaline, psilocybin and DMT, of which psychological effects are discussed in the article, are not properly understood and explained by the modern methods of neuroscience due to the lack of vigorous research. The involvement of some receptors, such as, [...]
Lire la suiteThe Religious Significance of Entheogenic Drugs Hugh Asher More Info: This is my unpublished Master's Dissertation. Abstract This paper examines the use of psychoactive substances such as Psilocybin, Mescaline, and LSD as adjuncts to mystical, religious or spiritual experiences. There is an analysis of the psychological changes and the changes in perception that these substances cause and how these can be interpreted as contributing to religious or spiritual enlightenment. There is also a discussion on the nature of what could be considered a religious experience. An overview of the use of such ‘entheogenic’ drugs from an historical perspective follows, looking specifically at the use of [...]

Cavnar (eds.), "Plant Medicines, Healing and Psychedelic Science", Springer International Publishing AG, part of Springer Nature 2018 doi : 10.1007/978-3-319-76720-8_12 Abstract DMT (N,N-dimethyltryptamine) is a powerful tryptamine that has experienced growing appeal in the last decade, independent from ayahuasca, the Amazonian visionary brew in which it is an integral ingredient. Investigating user reports available from literary and online sources, this chapter focuses on the gnosis potency associated with the DMT “breakthrough” experience. I explore the parameters of the tryptaminal state and, in particular, the extraordinary paragnosis associated with [...]

Doi : 10.1590/1516-4446-2019-4104 Depression is among the most important contributors to global disability and suicidal deaths. Available antidepressants are usually selective inhibitors of serotonin and norepinephrine uptake, which need weeks of daily intake before therapeutic effects appear, have limited efficacy for many patients, and induce significant adverse reactions after prolonged use. Therefore, recent research has focused on finding new antidepressant compounds that are fast-acting, more effective, and less toxic. The article recently published by da Silva et al. in the [...]

Despite increasing knowledge of the neural mechanisms involved in the acute effects of these drugs, the impact of sustained psychedelic use on the human brain remains largely unknown. Molecular pharmacology studies have shown that psychedelic 5-hydroxytryptamine (5HT)2A [...]

Strassman’s top selling book documented groundbreaking clinical trials with the powerful mind altering compound DMT (N,N-dimethyltryptamine) conducted at the University of New Mexico in the early 1990s. Inflected with Buddhist metaphysics, the book proposed that DMT secreted from the pineal gland enables transit of the [...]
