The Subtle Harms of Psychedelic-Assisted Therapy and Facilitation (Part 2) | Chemical Collective

The Meaghan Buisson case is enough to illustrate why psychedelic therapy can be, safeguards notwithstanding, a dangerous enterprise. Is the power imbalance realised and enhanced by 'transpersonal' psychologies a recipe for harm?

The Subtle Harms of Psychedelic-Assisted Therapy and Facilitation (Part 1) | Chemical Collective

Psychotherapy is often treated as one of the unquestioned goods of modern life, such that to criticise it is to risk appearing to deny mental suffering itself. What about its dangers - and how do those interact with psychedelics?

Let’s Talk About Non-Responders in Psychedelic Therapy | Chemical Collective

For a decade, many headlines, documentaries, and investor pitch decks have sold a singular story: that compounds like psilocybin and MDMA are capable of resetting the depressed brain and resolving trauma overnight. On August 9, 2024, that narrative collided with regulatory reality.

Psychedelic Bullshit? An Evaluation of The Immortality Key | Chemical Collective

Does Brian Muraresku's bestseller 'The Immortality Key' demonstrate that early Christians - and perhaps even Jesus himself - were consumers of a psychedelic-spiked communion wine? Unsurprisingly, no.

High on Power: How Much Does Ketamine Explain Elon Musk's Erratic Behaviour? | Chemical Collective

Does Elon Musk's alleged abuse of ketamine explain anything about his political behaviour? Is this a sign of 'drug-ism'? Or is it another symptom of a reality TV culture in which systematic problems are rendered in terms of colourful characters we watch on our phones?

The Philosophy of Mysticism: Perennialism vs Constructivism | Chemical Collective

Do mystical experiences reveal a shared transcendent reality?  Or, like any other category of contingent experience, are they better understood as products of their cultures? These questions mark one of the defining controversies in the modern study of religion, as well as shaping the extent to which we can co-exist in a hyper-globalised polis.

Terence McKenna's Mega Bad Trip | Chemical Collective

What unfolded during a terrifying mushroom trip in Hawaii between 1988 and 1989 would change Terence McKenna’s relationship with psychedelics – and perhaps reshape the message he shared with the world for the rest of his life.

Order, Chaos, and Consciousness: Examining the Entropic Brain Hypothesis | Chemical Collective

How does the coordinated activity of billions of neurons give rise to the richness of subjective experience? Among the many frameworks proposed is the Entropic Brain Hypothesis (EBH). First articulated by Robin Carhart-Harris and colleagues in 2014, EBH argues that the quality of consciousness can be indexed by the entropy – the randomness or diversity – of brain activity patterns. Is it true?

Non-Consensual Dosing in Psychedelic History | Chemical Collective

Today, we all accept that dosing people with psychedelic drugs is wrong. But this cannot be taken for granted, for it was an extremely popular practice in the 1960s. Some would theorise, for instance, that the 1960s began as a cultural phenomenon with a particular spiking incident in 1965 – around whose aftermath the whole Generation’s predatory character can be understood.

Beyond Blue Mondays: The Problem of Post-Psychedelic Depression | Chemical Collective

The day after a psychedelic trip is often described in two very different ways. For some, there’s the “afterglow”: a lingering sense of joy and clarity that can last days or even weeks. But there’s also a lesser-acknowledged counterpart: the psychedelic hangover, which may accompany an afterglow in some mitigated form. This can mean feeling drained, irritable, foggy, or emotionally flat in the hours or days after a session.  Sometimes, this dark mood doesn't stop, and people develop debilitating depressive disorders.

Tripping in the Material World: A Historical Materialist Analysis of Psychedelia | Chemical Collective

"It is not consciousness that determines life, but life that determines consciousness", wrote Marx and Engels. How much is 'the' 'psychedelic experience' shaped and conditioned by material economic forces?

Unreality Beyond The Patient

Derealisation has primarily been seen as an individual pathology, often linked to trauma or extreme stress. But the digitisation of everyday life and the increasing abstraction of government have transformed it into a collective affliction.
