Background and aimsThere is growing evidence that psilocybin, a serotonergic psychedelic substance, may be useful in the treatment of substance use disorders. However, there is a lack of data on the beliefs and attitudes towards psilocybin amongst Black individuals diagnosed with Opioid Use Disorder (OUD). This study characterized psilocybin use patterns and...
The use of low sub-perceptual doses of psychedelics ("microdosing") has gained popularity in recent years. Although anecdotal reports claim multiple benefits associated with this practice, the lack of placebo-controlled studies severely limits our knowledge of microdosing and its effects. Moreover, research conducted in standard laboratory settings could fai...
The use of low doses of psychedelic substances (microdosing) is attracting increasing interest. This systematic review summarises all empirical microdosing research to date, including a set of infrequently cited studies that took place prior to prohibition. Specifically, we reviewed 44 studies published between 1955 and 2021, and summarised reported effects ...
This is a narrative review about the role of classic and two atypical psychedelics in the treatment of unipolar and bipolar depression. Since the 1990s, psychedelics experience a renaissance in biomedical research. The so-called classic psychedelics include lysergic acid diethylamide (LSD), psilocybin, mescaline and ayahuasca. Characteristic effects like alt...
BackgroundClassic psychedelics, such as psilocybin and LSD, and other serotonin 2A receptor (5-HT2AR) agonists evoke acute alterations in perception and cognition. Altered thalamocortical connectivity has been hypothesized to underlie these effects, which is supported by some functional MRI (fMRI) studies. These studies have treated the thalamus as a unitary...
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...
Psilocybin is a naturally occurring psychedelic compound with profound perception-, emotion- and cognition-altering properties and great potential for treating brain disorders. However, the neural mechanisms mediating its effects require in-depth investigation as there is still much to learn about how psychedelic drugs produce their profound and long-lasting...
The word "psychedelic" (psyche (i.e., the mind or soul) and delos (i.e., to show)) has Greek origin and was first coined by psychiatrist Humphry Osmond in 1956, who had been conducting research on lysergic acid diethylamide (LSD) at the time. Psychedelic drugs such as N,N-DMT/DMT (N,N-dimethyltryptamine), 5-MeO-DMT (5-methoxy-N,N-dimethyltryptamine), LSD (ly...

Psychotherapy with the use of psychedelic substances, including psilocybin, lysergic acid diethylamide (LSD), ketamine, and 3,4-methylenedioxymethamphetamine (MDMA), has demonstrated promise in treatment of post-traumatic stress disorder (PTSD), anxiety, addiction, and treatment-resistant depression. Psychedelic-assisted psychotherapy (PP) represents a uniqu...
ABSTRACT Background Serotonin 2A receptor (5-HT 2AR ) agonist psychedelics including psilocybin and LSD (“classic” psychedelics) evoke acute alterations in perception and cognition. Altered thalamocortical connectivity has been proposed to underlie these effects, which is supported by some functional MRI (fMRI) studies. Likely due to sample size limitations,...
Despite an increasing body of research highlighting their efficacy to treat a broad range of medical conditions, psychedelic drugs remain a controversial issue among the public and politicians, tainted by previous stigmatisation and perceptions of risk and danger. This narrative review examines the evidence for potential harms of the classic psychedelics by ...
BackgroundLSD and psilocybin are increasingly used in phase I trials and evaluated as therapeutic agents for mental disorders. The phenomenon of reoccurring drug-like experiences after the acute substance effects have worn off was described for both substances and especially attributed to LSD. According to the DSM-V, the persisting and distressing manifestat...
“Are magic mushrooms the miracle cure for depression we've been looking for?” (Khan, 2021). Attention-grabbing headlines such as this are becoming increasingly common and suggest that psychedelic medicines are some kind of magic bullet. This perception is increased by stories of people who had a single life-changing psychedelic experience that resulted in co...
Obsessive-Compulsive Disorder (OCD) is a chronic psychiatric anxiety disorder distinguished by obsessive thoughts and repetitious actions. Current therapies for OCD are not very effective and have many possible side-effects. Psychedelics are a class of Schedule I substances that are re-emerging as novel therapeutics for a variety of psychiatric conditions. T...
This study seeks to understand the neural, cognitive and behavioral effects of low doses of psilocybin administered in the form of dried mushroom material (0.5 g of Psilocybe cubensis) consumed in natural settings following a placebo-controlled double-blind experimental design. Sub-threshold doses of serotonergic psychedelics are frequently consumed as cogni...
Synaptopathies (Fall, 2022) Synaptic neurotransmission lies at the heart of nervous system's functioning. Clearly then, alterations in synaptic signal transduction can lead to a variety of neural disorders. Perhaps the most widely known of these disorders include certain movement disorders and myasthenia gravis. More recent interest in synaptic dysfunction h...
The use of low sub-hallucinogenic doses of psychedelics (“microdosing”) has gained popularity in recent years. Although anecdotal reports claim multiple benefits associated with this practice, the lack of placebo-controlled studies limits our knowledge of microdosing and its effects. Moreover, research conducted in laboratory settings might fail to capture t...

As source of sensory information, the body provides a sense of agency and self/non-self-discrimination. The integration of bodily states and sensory inputs with prior beliefs has been linked to the generation of bodily self-consciousness. The ability to detect surprising tactile stimuli is essential for the survival of an organism and for the formation of me...
