There are profound methodological challenges facing microdosing research. One way we can address some of these methodological issues is by understanding how psilocybin microdosing fits in the broader existential context of people’s lives. We recruited participants who underwent psilocybin microdosing on their own and consented to being monitored for harm mit...
Abstract Objectives The first line for symptom management of attention deficit hyperactivity disorder (ADHD) is a class of medications that act on dopamine and noradrenaline receptors, which leads to symptom reduction at the cost of significant side effects. These side effects have led to community searching for alternative methods that manage ADHD symptoms ...
Background: Research investigating high-dose, high-support psilocybin-assisted therapy reports significant psychological benefits, increased consciousness, and an enhanced socio-cognitive niche, resulting in empathy, connection, creativity, and overall well-being. These qualities lend themselves well to the bonding, emotional regulation, and attachment requi...
5-MeO-DMT is a psychedelic substance with a short duration of action and intensive effects. Its therapeutic efficacy and practicality may significantly surpass those of classical psychedelics such as ayahuasca and LSD. This retrospective ethnographic inquiry features a woman in her mid-thirties who witnessed her mother's violent suicide and its bloody afterm...
Because psychedelics have been found to increase psychological traits like openness, mental flexibility, and interpersonal perceptiveness, some researchers believe that psychedelics could help individuals cope with the psychological effects of discrimination. However, it is still unclear whether psychedelic use can help manage the internalized stigma that de...
Recent studies suggest psychedelic use may be associated with changes in a variety of beliefs or belief-like states, including increased 1) mind perception, 2) non-naturalistic beliefs, and 3) Atheist-Believer status (e.g. believer, agnostic, or nonbeliever). We conducted a prospective longitudinal study among participants (N = 657) who planned to have a psi...
Psilocybin is a serotonergic psychedelic shown to have enduring antidepressant effects. Currently, the mechanism for its enduring effects is not well understood. Empathy and prosocial behavior may be important for understanding the therapeutic benefit of psilocybin. In this article we review the effect of psilocybin on empathy and prosocial behavior. Moreove...
Expectancy effects for many psychoactive substances appear to play a role in consumption, problematic use, subjective responses to acute administration, and subsequent effects. Expectancies of psychedelics have received little attention in published research despite their reputation for creating dramatic changes in subjective state. Psilocybin-assisted treat...

Taking a chronological approach, it investigates the way mescaline, LSD, and psilocybin were administered, the subjects involved, the route of administration, the dosage, and the epistemological context of the research. From ...

Background: Psychedelic drug experiences are shaped by current-moment contextual factors, commonly categorized as internal (set) and external (setting). Potential influences of past environments, however, have received little attention. Aims: To investigate how previous environmental stimuli shaped the experiences of patients receiving ketamine for treatment...

The Psychological Insight Questionnaire (PIQ), Challenging Experiences Questionnaire (CEQ), and Mystical Experiences Questionnaire (MEQ) were translated before being incorporated into a web-based survey. We recruited native Spanis...
Since reports about CIA-funded LSD studies came out in the 1970s, psychedelic drugs have invoked images of unethical experimentation and “mad scientists” in the public imagination. Even now, as the stigma surrounding psychedelics diminishes in the 21st century, the figure of the “mad scientist” continues to occupy a space in what Ido Hartogsohn calls the “co...
In a recent article, Messell and colleagues provide a curated list, the "Copenhagen Music Program for Psilocybin". We test their music program with an experienced Indigenous therapist/psychonaut on a 3.5 gram psilocybin journey. Based on comments provided by the Indigenous therapist, we find the program contains musical choices that evoke specific colonial a...
