While the movement to liberalize psychedelics bears many parallels to that of cannabis, there are important differences that must be considered in development of regulatory policy. It is critical to avoid conflating debates about liberalization for therapeutic and recreational purposes. As with cannabis, this conflation has been driven by advocates of recrea...
Serotonergic psychedelics induce altered states of consciousness and have shown potential for treating a variety of neuropsychiatric disorders, including depression and addiction. Yet their modes of action are not fully understood. Here, we provide a novel, synergistic understanding of psychedelics arising from systematic reviews and meta-analyses of three h...
ABSTRACT Psychedelics have robust effects on acute brain function and long-term behavior but whether they also cause enduring functional and anatomical brain changes is unknown. In a placebo-controlled, within-subjects, electroencephalography, and magnetic resonance imaging study in 28 healthy, entirely psychedelic-naive participants, anatomical and function...
Psilocybin is a classic psychedelic and a novel treatment for mood disorders. Psilocybin induces dose-dependent transient (4-6 hours) usually pleasant changes in perception, cognition, and emotion by non-selectively agonizing the 5-HT2A receptors and negatively regulating serotonin reuptake, and long-term positive antidepressant effect on mood and well-being...

Introduction: Treatment-outcome expectancies are an individual’s beliefs about how a medical or psychological intervention will affect them and others. These response expectancies represent serious potential confounds to clinical trials of psychedelic-assisted therapies for a variety of conditions because of difficulties associated with blinding psychedelic ...
There has been little research on the effects of psychedelics on menstrual and reproductive function, though anecdotal evidence suggests that these compounds may have striking effects on menstrual function in at least a subset of users. Social media and word of mouth were used to seek out individuals who had a history of changes in menstrual function followi...
A growing body of work shows that autonomic signals provide a privileged evidence-stream to capture various aspects of subjective and neural states. This work investigates the potential for autonomic markers to track the effects of psychedelics - potent psychoactive drugs with important scientific and clinical value. For this purpose, we introduce a novel Ba...

Introduction: There is substantial public interest in psychedelics as potential treatments for psychiatric conditions. However, most psychedelics are criminalized under federal law in the USA, so it is unclear whether use occurs with clinical support. Our objective was to assess whether naturalistic psychedelic use occurs with clinical support, interactions ...
The Altered Xperience Project (AXP) is an ongoing research project that takes the form of an open citizen science initiative. Its main goal is to systematically collect and consolidate data on the subjective experiences induced by various consciousness-manipulating techniques (CMTs). These include both psychoactive substances as well as non-pharmacological m...

The substantial challenges facing high and low dose psychedelic drug development to achieve regulatory approval have been documented in the scientific literature. These limitations have not deterred drug developers and social media from repeatedly misleading patients, the public and health professionals. Developing "micro doses" of psychedelics overcomes man...
Identifying gaps and strengths in psychedelic-related knowledge is key to developing effective, evidence-based education to inform appropriate use of and harm reduction practices for psychedelics in the naturalistic use landscape. The current study piloted an assessment instrument with questions on legal status, therapeutic potential, and side effects of psy...
This theoretical article revives a classical bridging construct, canalization, to describe a new model of a general factor of psychopathology. To achieve this, we have distinguished between two types of plasticity, an early one that we call 'TEMP' for 'Temperature or Entropy Mediated Plasticity', and another, we call 'canalization', which is close to Hebbian...
Background: The Relaxed Beliefs Under pSychedelics (REBUS) model proposes that serotonergic psychedelics decrease the precision weighting of neurobiologically-encoded beliefs, and offers a unified account of the acute and therapeutic action of psychedelics. Although REBUS has received some neuroscientific support, little research has examined its psychologic...
Sir, Psychedelic studies have reported positive results for depression and anxiety related to cancer and other life-threatening illnesses, treatment-resistant depression, and tobacco and alcohol dependence.[1] Although there are no active psychedelic research studies going on in India, there is growing interest about these substances as evident by numerous s...
Objective: The Royal Australian and New Zealand College of Psychiatrists (RANZCP) has positioned itself against medically controlled patient access (at this current time) to 3,4-methylenedioxymethamphetamine (MDMA) and psilocybin-assisted therapies in its Therapeutic Use of Psychedelic Substances Clinical Memorandum, May 2020. The main reason given by the RA...
