A large body of historical evidence describes the use of hallucinogenic compounds, such as psilocybin mushrooms, for religious purposes. But few scientific studies have attempted to measure or characterize hallucinogen-occasioned spiritual experiences. The present study examined the factor structure of the Mystical Experience Questionnaire (MEQ), a self-report measure that has been used to asse...
A web-based survey was used to consult the opinions of experienced drug users on matters related to drug harms. We identified a rare sample of 93 drug users with personal experience with 11 different illicit drugs that are widely used in the UK. Asked to assess the relative harms of these drugs, they ranked alcohol and tobacco as the most harmful, and three "Class A" drugs (MDMA, LSD, and psilo...
Morphological and toxicological analyses were performed on hallucinogenic mushrooms that are currently circulated in Japan. Scanning electron microscope (SEM) indicated a three-dimensional microstructures in the mushrooms. The complementary use of SEM with an optical microscope was effective for observing characteristic tissues, such as basidiomycetes, spores, cystidia and basidia. Hallucinogen...
Mycelial cultures of Psilocybe cubensis capable of forming psilocybin and psilocin de novo display a high capacity for hydroxylation of tryptamine derivatives at the 4-position. A specific biotransformation of added synthetic N,N-diethyl-tryptamine was found. Thus high amounts of 4-hydroxy-N,N-diethyltryptamine (up to 3.3%) and a minor quantity of 4-phosphoryloxy-N,N-diethyltryptamine (0.01-0.8...
Selective serotonin uptake inhibitors (SSRIs) are known to stimulate the production of new neurons in the hippocampus (HPC) by increasing synaptic concentration of serotonin (5-HT). The delay in the appearance of antidepressant effects corresponds to the time required to generate new neurons. However, it is not clear which of the many serotonergic receptors in the HPC are responsible for the en...
