4‐phosphorloxy‐ N,N ‐dimethyltryptamine (psilocybin) is a naturally occurring psychedelic compound that is being investigated in clinical studies in conjunction with psychotherapy for treatment of several psychiatric disorders. It is well established that 4‐hydroxy‐ N,N ‐dimethyltryptamine (psilocin) is the bioactive metabolite of psilocybin which mediates its in vivo psychedelic activity in...

Dreams are virtual repetitions during sleep, of what we perceive and act, in reality, when we are awake. The basis of wakeful state, is due to the sensory inputs from the sensory organs (through the ascending tracts) and the motor output from the respective brain centres (through the descending tracks), as well as, due to the activated ascending reticular activating system. (ARAS) and the...

In this précis I summarise the main ideas of my book Philosophy of Psychedelics. The book discusses philosophical issues arising from the therapeutic use of “classic” (serotonergic) psychedelic drugs such as psilocybin and LSD. The book is organised around what I call the Comforting Delusion Objection to psychedelic therapy: the concern that this novel and promising treatment relies essentially...

<p><b>Depressive and anxiety disorders are debilitating psychiatric illnesses that affect a substantial portion of the world population. Current pharmaceutical interventions, such as selective serotonin reuptake inhibitors, are generally regarded as front-line treatments but are not universally effective at reducing symptomology. Psilocybin, the active component in Psilocybe cubensis mushrooms,...

Psilocybin therapy shows antidepressant potential, but its therapeutic actions are not well understood. We assessed the subacute impact of psilocybin on brain function in two clinical trials of depression. The first was an open-label trial of orally administered psilocybin (10 mg and 25 mg, 7 d apart) in patients with treatment-resistant depression. Functional magnetic resonance imaging (fMRI)...

Psychedelics are a class of drugs that produce unique subjective effects via agonist actions at the 5-hydroxytryptamine 2A receptor (5-HT2A). The 5-HT2A-mediated head twitch response (HTR) in rodents is used as a reliable proxy for psychedelic drug activity in humans, but existing methods for measuring HTRs require surgery or time-consuming visual scoring. In the present work, we validated a...

A growing body of research suggests that psychedelic compounds may be useful for treating patients with certain disorders. As highlighted by several sessions at the APA Annual meeting, there’s a growing renewed interest in psychedelics, which are compounds that induce changes in thought, perception, and mood, in the clinical and research communities. Classic psychedelics refer to a subset whose...

At first glance, it appears there is little difference between the molecular structures of methylenedioxymethamphetamine (MDMA), which has an N -methyl attached to its amino group, and methylenedioxyamphetamine (MDA), a primary amine that is recognized to have hallucinogenic activity. It is known from studies with other hallucinogenic amphetamines that N -methylation of hallucinogenic...

Recently, there has been an increase in studies yielding evidence for psychedelics' anxiolytic and anti-depressive qualities. Preliminary evidence for treatment in substance addiction is also available. In our manuscript, we present a perspective on the possible effectiveness and mechanisms of action of psychedelics' introduction in the treatment of Compulsive Sexual Behavior Disorder (CSBD)...
