Michael Pollan's 480-page "How to Change Your Mind" compellingly argues that psychedelics, particularly psilocybin, could revolutionize mental health. Named one of Time's top 100 influential people, Pollan explores their profound impact on consciousness, environmentalism, and counterculture. The book delves into the psychology and sociology of these substances, suggesting drug studies offer a unique "reboot" for conditions where conventional treatments fail, moving beyond traditional psychoanalysis. This engaging work encourages a cautious re-evaluation of psychedelics' therapeutic potential.

Abstract

It is tough to write about psychedelics without a few gratuitous puns. Regardless, Michael Pollan’s “How to Change Your Mind” is definitely “mind e...

Self-Reported Illicit Drug Use Among Norwegian University and College Students. Associations With Age, Gender, and Geography

Frontiers in Psychiatry  – December 10, 2020

Summary

Illicit drug use among Norwegian university students is climbing. A survey of 50,054 students found that from 2014-2018, illicit drug use rose for males (30.8% to 36.7%) and females (17.5% to 24.0%). Cannabis (15.2%) was the most common drug in the past year. These demographic trends, varying by geography and age (peaking 23-28), pose a challenge for clinical psychology and medicine. Robust substance abuse treatment, including for opioid use disorder, and mental health access are crucial for student environmental health in Norway.

Abstract

Background and Aims: Several studies have pointed to relatively high levels of illicit drug use among students in higher education compared to the ...

Reported effects of psychedelic use on those with low well-being given various emotional states and social contexts

Drug Science Policy and Law  – January 01, 2020

Summary

Individuals with low psychological well-being (643 respondents) were more likely to report positive mood changes after using psychedelics like lysergic acid diethylamide or psilocybin, and MDMA. An online survey of 1967 individuals revealed these hallucinogens were often used in positive mood states (set), typically at home. Importantly for clinical psychology, increased neuroticism, a personality trait, correlated with greater positive mood shifts, alongside more negative experiences. This highlights potential for psychiatry in Psychedelics and Drug Studies.

Abstract

Background It has been suggested that the outcome of the psychedelic experience is dependent on set and setting. While scientific research into the...

2018: A watershed year for psychedelic science

Drug Science Policy and Law  – January 01, 2019

Summary

The year 2018 profoundly transformed Psychedelics and Drug Studies. A key acknowledgement came when the Food and Drug Administration designated psilocybin-assisted psychotherapy a "breakthrough therapy" for depression. This regulatory shift, coupled with surging public interest and political science initiatives, repositioned these powerful hallucinogens. The momentum ignited diverse academic research themes, spanning psychology, social science, and even environmental ethics, solidifying the field's long-term outlook beyond just chemical synthesis and alkaloids.

Abstract

While interest in the study of psychedelic drugs has increased over much of the last decade, in this article, we argue that 2018 marked the true tu...

Serotonin, psychedelics and psychiatry

World Psychiatry  – September 07, 2018

Summary

In Psychiatry, just one or two psychedelic treatment sessions can yield therapeutic effects lasting several months for mood disorders and addiction—an unprecedented outcome. Neuropsychopharmacology reveals Serotonin's complex role, with 5-HT2A neurotransmitter receptor influence on behavior being key to the "psychedelic experience" and heightened context sensitivity. This shift in Medicine and Drug Studies, moving beyond traditional psychoanalysis and simple Serotonin deficiency models, highlights new Psychology avenues exploring how these compounds, often alkaloids, profoundly impact mental health.

Abstract

Serotonin is a key neuromodulator known to be involved in brain development, perception, cognition, and mood. However, unlike as with dopamine for ...

Psychedelics, the Spiritual and Consciousness—an Evolving Confluence in the Cultural Stream

Tikkun  – January 01, 2018

Summary

A compelling finding from a survey of 893 participants reveals that ego dissolution during psychedelic experiences predicts liberal political views, openness, and nature relatedness, while negatively predicting authoritarianism. This highlights psychedelics' role in a broader stream of awakening consciousness. Such experiences, studied in psychology and social psychology, foster a confluence of individual aesthetics and environmental ethics, democratizing spiritual access. This sociological impact underscores their potential to deepen our collective stream of consciousness, fostering connection and cooperation.

Abstract

in this time of ever ascendant materialism, greed, and pathological narcissism, when the delusion of the disconnected dominant individual grows str...

Lifetime experience with (classic) psychedelics predicts pro-environmental behavior through an increase in nature relatedness

Journal of Psychopharmacology  – June 20, 2017

Summary

Experience with classic hallucinogens like psilocybin and mescaline strongly predicts pro-environmental behavior, a compelling Psychology finding from a 1,487-person general population study. This effect, relevant to social psychology, is explained by a deeper self-identification with nature, independent of Big Five personality traits such as conscientiousness or openness to experience. These Psychedelics and Drug Studies highlight how neurotransmitter receptor influence on behavior can foster ecological conscientiousness, suggesting unique societal benefits beyond individual mental wellbeing.

Abstract

In a large-scale ( N = 1487) general population online study, we investigated the relationship between past experience with classic psychedelic sub...
