Abstract Although less common than abuse of marijuana and cocaine, abuse of magic mushroom, peyote cactus, lysergic acid diethylamide (LSD), khat, and volatiles is observed in the United States. Eating wild mushroom is dangerous because misidentification of toxic mushroom as magic mushroom may be fatal. Magic mushroom contains psilocybin and psilocin but major psychedelic action of magic...
Conventional antidepressants (biogenic amine mechanisms) are not fully efficacious (e.g., symptoms remain after treatment, not all patients respond), produce effects only after weeks of daily dosing, and do not impact all disease symptoms. In contrast, a new class of antidepressants has been emerging since 2006 that has demonstrated rapid onset, large effect size, activity after only a single...
This chapter aimed to provide an overview of the large number of hallucinogens of natural origin. Following a literature review, the following hallucinogens were selected for a detailed description that considered their essential chemical groups: indoleamines ( N,N -dimethyltryptamine, 5-methoxy- N,N -dimethyltryptamine, bufotenine, psilocybin, and ibogaine), phenylethylamines (mescaline),...
Given the growing popularity of Ayahuasca, we sought to identify why people might use this psychoactive brew rather than classic hallucinogens like LSD or psilocybin. Experienced users (N=139) completed an online survey about their use of hallucinogens, including ayahuasca, how their ayahuasca experiences differed from those with other hallucinogens, and their willingness to use ayahuasca over...
Psychedelic drugs, often referred to as hallucinogens, are quite distinct from other classes of psychotropic drugs. Although the subjective and behavioral effects they induce are quite dramatic, they possess little addictive potential when compared to nicotine, alcohol or opiates. Since the discovery of ketamine antidepressant effects, there has been growing interest for these molecules....
New studies in end-of-life depression, OCD, resistant depression, smoking and alcohol addiction have revealed powerful effects for psilocybin These need to be replicated in major double-blind controlled studies Historical use of psychedelics that ended in the 1960s revealed they had considerable utility in a number of psychiatric conditions especially addiction and affective disorders Over the...
Cet article vise à montrer que la bombe atomique a eu des effets psychotropes sur la conscience américaine. Il propose d’étendre la signification du terme « psychotrope » afin d’englober la tropologie de la bombe atomique et le tournant initié par l’apparition de la bombe au milieu du xx e siècle. L’analyse porte sur une variété d’exemples de « culture nucléaire » issus de la photographie, du...
The goal of this work was to investigate and compare the selectivity of three different hydrophilic interaction liquid chromatography (HILIC) charge modulated amide columns, iHILIC®-Fusion, iHILIC®-Fusion(+) and iHILIC®-Fusion(P), for analysis of compounds in hallucinogen mushrooms. An extract of a truffle-like fungus containing psilocin, psilocybin and baeocystin was chosen as test material....
The development of 5-HT2A receptor agonists has been considerably marginalized since the demonstration that the tryptaminergic drugs, LSD and psilocybin, or the phenylakylamine drugs, mescaline and DOI, exert their hallucinogenic properties via the stimulation of 5-HT2A receptors. Nonetheless, the ability of drugs to stimulate 5-HT2A receptors is not necessarily associated with psychedelic...
Three years ago, when I accepted a position as Director of Clinical and Translational Research at Usona Institute, a non-profit medical research organization pursuing a new drug indication for the psychedelic medicine psilocybin, many of my colleagues in mental health research looked at me like I had two heads. A year later, many of these same colleagues were beginning to ask me how they could...
