This talk explores the evolutionary, geographic, and cultural origins of the plant technology commonly known as ayahuasca. Drawing on Neil Logan’s article for Microcosms: Sacred Plants of the Americas, the presentation examines the taxonomy, morphology, traditional lore, and ongoing debates surrounding different varieties of Banisteriopsis caapi.

In recent decades, mycologists and mycophiles have worked to dispel the myths and misunderstandings that have historically maligned fungi. Many of those arose before we understood their ways. Yet misinformation around mushrooms persists, fuelled at times by a fetish for sensationalism and misguided perceptions of risk.

Ethnomycological knowledge has filtered down through generations of cultures around the world, across the millennia. A wide spectrum of species used as food and medicine, in rituals and more reflects the rich and contextualised understanding arising from direct observation and deep hanging out with fungi.

Terence McKenna was the 20th century’s psychedelic renaissance man. In this talk, we’ll squeeze into the back seat of McKenna’s 1997 tour of Australia. For a brief moment in Feb/Mar of that year, McKenna served as alien frontman for the Aussie experimental music underground. In our journey, we’ll explore the visitor’s enigmatic stature as a cult figure, novelty theorist, and psychedelic prophet with an untiring vision: that the clock is running down on history.

The genus Anadenanthera encompasses some of the most culturally and ecologically significant entheogenic trees of the Americas. With a long history of ritual use, these leguminous trees— closely related to Acacia and Mimosa—are native to the dry forests and savanna biomes of South America. Species such as A. peregrina (Yopo, Cojoba) and A. colubrina (Wilca, Cebil) have been implicated in ancient visionary practices and may even play a role in the early development of the ayahuasca complex.

An autobiographical tale narrated by a close witness to a curious life, this is meant to be a guided journey through my experience of the early days of psychedelic culture in the United States. 
I feel drawn to share. Some of these tales cannot be had again by anyone. Some are evidence of Dr Lilly’s “Earth Coincidence Control Office” hard at work.



I set out as a young fella to explore the range of possibilities of my mind, and to find others who were doing the same. It was a time of discovery. Boundaries unseen were discovered, crashed into, dissolved, and passed through… those left behind often had no idea where I went, or what life I had found on the other side. It was a liminal time, a time between realities in which there was loss and gain and change. I embraced it all.

Good news, everybody! Well at age 65? You're likely to make it to 90. Well at 50? You're likely to make it to 95 - and beyond. We have gained an incredible gift of 'time enough' - but are we ready?

A big study published last year showed a massive gap between lifespan and 'healthspan' - the number of years of 'good enough' health we enjoy. In Australia that gap runs to more than twelve years - and it's nearly as bad in New Zealand. Who wants to spend the last dozen years of their very long lives dreading their decline?

Lophophora williamsii (peyote) is a slow-growing, culturally significant cactus native to the Chihuahuan Desert and parts of South Texas and northern Mexico. It is currently facing conservation challenges due to pressures from habitat loss, land-use change and unsustainable harvesting for ceremonial and non-traditional uses.

It is an exciting time for psychedelic healing in Aotearoa New Zealand, with the first clinic for psilocybin-assisted therapy opening its doors in May 2025 and a first round of government guidance on how to apply to set up psychedelic clinics released in July 2025. There is also a growing call for Māori to be able to access endemic psychedelic mushrooms outside of controlled substances legislation.

This presentation will explore the rationale, results, and implications of our neurophenomenological, psychedelic studies with short acting tryptamines from the DMT Research Group at Imperial College London’s Centre for Psychedelic Research, and the UCL Centre for Consciousness Research. Just as modern particle colliders have advanced scientific perspectives on the underlying structure and qualities of our physical universe, our research operates under the rationale that psychedelic plants, molecules, and medicines are a vital tool for perturbing and studying human consciousness and its relationship to the brain.

Over the past forty years, a core group of psychedelic advocates has made concerted efforts to mainstream psychedelics through the process of “turning psychedelics into medicine.” In pursuit of this goal of psychedelic medicalisation, its advocates have used a public relations strategy involving the promotion of “psychedelic science” as a discipline that explores the treatment of “treatment resistant conditions” as well as the resolution of international conflicts, climate change, and other existential crises.

This is a tale of synchronicities, revisiting unlikely intersections and new understandings. Once beyond family, late 60s, I was a free agent in a time of profound social change. I chose to take chances, to trust my intuition. When psychedelics came my way I was eager to explore. Not long on the ‘poison path’ I found a boundary to honour. I imposed a limit, committing to its use in natural surroundings, alone or with a supportive ally. My interest in psychedelics focused on ‘mind expansion’ and revelation, primarily using LSD and Peyote. I improvised a yoga practice of Asanas, study of esoteric texts, lightshows, and meditation.

Ayahuasca brews are traditionally prepared with the leaves of Psychotria viridis or Diplopterys cabrerana, yet the latter has long been the subject of taxonomic confusion. Once thought to be synonymous with Banisteriopsis rusbyana, D. cabrerana has undergone decades of misidentification, conflation, and reclassification.

Tū Wairua is a Māori Health Science collaboration led by Rangiwaho Marae, (Ngai Tāmanuhiri) in Te Tairāwhiti, Gisborne, Aotearoa (New Zealand). Tū Wairua embraces the reawakening and reclamation of sacred ceremony and ritual in healing to reconnect Māori collectively to the wider ecological and energetic systems in which we find ourselves misalignedfrom in the post-colonial world.

Background: Thousands of people use psilocybin (‘magic’) mushrooms annually in New Zealand, with around half of these people having used them to self-medicate mental health disorders. Use of psilocybin mushrooms risks drug-associated harm such as consumption of toxic or contaminated mushrooms, bad trips’, muscle paralysis, or hallucinogen persisting perception disorder.

The evolution and growth of the Legalise Cannabis movement in Australia, from grassroots activism to registered political entities.

The Legalise Cannabis Parties evolved from a grassroots movement that began in the '70s, with the founding of the Australian branch of NORML (National Organisation for the Reform of Marijuana Laws).

Harry Pack

In this talk, artist Harry Pack explores how creative expression can be a powerful tool for integrating altered states, supporting mental health, and deepening self-understanding. Drawing from his own journey, he shares how art has helped him make sense of visionary experiences and emotional healing.

He will introduce The Purple UFO, a collaborative platform that uses art as a bridge between inner transformation and community connection—bringing people together through shared creativity, nature-inspired practice, and open conversation around consciousness and integration.

Cannabis has deep roots in Indian culture, appearing in legends, religion, and daily life. The earliest references are found in the Vedas, sacred Hindu texts compiled between 2000 and 1400 B.C. According to the Vedas, cannabis was one of five sacred plants, believed to be inhabited by a guardian angel. It was described as a source of happiness, a giver of joy, and a liberator—compassionately gifted to humanity to ease suffering, bring delight, and dissolve fear.

Across the globe, psychedelic medicine is provided through a striking diversity of practitioners and settings. This includes psychedelic therapists, assistants, curanderos, maestros, chaplains, facilitators, coaches, guides, companions, neo-shamans, and others. While psychedelic substances travel easily enough today, the ways of guiding them vary considerably.
