Terence McKennaTerence Kemp McKenna (November 16, 1946 – April 3, 2000) was an American ethnobotanist and mystic who advocated the responsible use of naturally occurring psychedelic plants. He spoke and wrote about a variety of subjects, including psychedelic drugs, plant-based entheogens, shamanism, metaphysics, alchemy, language, philosophy, culture, technology, ethnomycology, environmentalism, and the theoretical origins of human consciousness.
Neuroscience of religionThe neuroscience of religion, also known as neurotheology and as spiritual neuroscience, attempts to explain religious experience and behaviour in neuroscientific terms. It is the study of correlations of neural phenomena with subjective experiences of spirituality and hypotheses to explain these phenomena. This contrasts with the psychology of religion which studies mental, rather than neural states. Proponents of the neuroscience of religion say there is a neurological and evolutionary basis for subjective experiences traditionally categorized as spiritual or religious.
Psychoactive cactusMany cacti are known to be psychoactive, containing phenethylamine alkaloids such as mescaline. However, the two main ritualistic (folkloric) genera are Echinopsis, of which the most psychoactive species is the San Pedro cactus (Echinopsis pachanoi, syn. Trichocereus pachanoi), and Lophophora, with peyote (Lophophora williamsii) being the most psychoactive species. Several other species pertaining to other genera are also psychoactive, though not always used with a ritualistic intent.
ErowidErowid, also called Erowid Center, is a non-profit educational organization that provides information about psychoactive plants and chemicals. Erowid documents legal and illegal substances, including their intended and adverse effects. Information on Erowid's website is gathered from diverse sources including published literature, experts in related fields, and the experiences of the general public. Erowid acts as a publisher of new information as well as a library for the collection of documents and images published elsewhere.
Psychedelic therapyPsychedelic therapy (or psychedelic-assisted therapy) refers to the proposed use of psychedelic drugs, such as psilocybin, MDMA, LSD, and ayahuasca, to treat mental disorders. As of 2021, psychedelic drugs are controlled substances in most countries and psychedelic therapy is not legally available outside clinical trials, with some exceptions. The procedure for psychedelic therapy differs from that of therapies using conventional psychiatric medications.
Beta-Carbolineβ-Carboline (9H-pyrido[3,4-b]indole) represents the basic chemical structure for more than one hundred alkaloids and synthetic compounds. The effects of these substances depend on their respective substituent. Natural β-carbolines primarily influence brain functions but can also exhibit antioxidant effects. Synthetically designed β-carboline derivatives have recently been shown to have neuroprotective, cognitive enhancing and anti-cancer properties. The pharmacological effects of specific β-carbolines are dependent on their substituents.
Anadenanthera peregrinaAnadenanthera peregrina, also known as yopo, jopo, cohoba, parica or calcium tree, is a perennial tree of the genus Anadenanthera native to the Caribbean and South America. It grows up to tall, and has a horny bark. Its flowers grow in small, pale yellow to white spherical clusters resembling Acacia (e.g. wattle) inflorescences. It is an entheogen which has been used in healing ceremonies and rituals for thousands of years in northern South America and the Caribbean.
Psychoactive plantPsychoactive plants are plants, or preparations thereof, that upon ingestion induce psychotropic effects. As stated in a reference work: Psychoactive plants are plants that people ingest in the form of simple or complex preparations in order to affect the mind or alter the state of consciousness. Psychoactivity may include sedative, stimulant, euphoric, deliriant, and hallucinogenic effects. Several hundred psychoactive plants are known.
Religious Freedom Restoration ActThe Religious Freedom Restoration Act of 1993, Pub. L. No. 103-141, 107 Stat. 1488 (November 16, 1993), codified at through (also known as RFRA, pronounced "rifra"), is a 1993 United States federal law that "ensures that interests in religious freedom are protected." The bill was introduced by Congressman Chuck Schumer (D-NY) on March 11, 1993. A companion bill was introduced in the Senate by Ted Kennedy (D-MA) the same day. A unanimous U.S. House and a nearly unanimous U.S.
Entheogenic drugs and the archaeological recordEntheogenic drugs have been used by various groups for thousands of years. There are numerous historical reports as well as modern, contemporary reports of indigenous groups using entheogens, chemical substances used in a religious, shamanic, or spiritual context. A Finnish study assayed psilocybin concentrations in old herbarium specimens, and concluded that although psilocybin concentration decreased linearly over time, it was relatively stable. They were able to detect the chemical in specimens that were 115 years old.
