This symposium, hosted by the Psychedelic and Enthegeon Academic Council (PEAC) at the University of California San Francisco (UCSF), and the Multidisciplinary Association for Psychedelic Studies (MAPS), will be focused on advancing the discussions around doing clinical trials in the United States to assess the safety and efficacy of ayahuasca in healthy participants and PTSD patients.  The meeting aims to leverage the expertise of Brazilian researchers who have successfully conducted clinical trials on ayahuasca, and other related topics in the field of psychedelic science. Some of the questions addressed include: What methodological and epistemological challenges arise when conducting clinical research into psychedelic substances?; How are participants and researchers benefiting from the interventions, and how might trials be designed to best document this?; How is the placebo effect framed and shaped by clinical trial methodologies, and how could it be framed differently?; What kind of a ‘problem’ is placebo?; What role do the psychedelics themselves play in the learning processes of participants and researchers, and how should we understand the roles that other factors play?; Can the knowledge we are gaining about psychedelics be translated across different substances, sets, settings and disciplinary registers?

Challenges and Questions Behind a Clinical Trial with Ayahuasca for Depression
Draulio Araujo, Ph.D, UFRN

Research with serotonergic psychedelics has gained momentum. A few centres around the world are currently exploring how these substances interact with the brain, and probing their potential use in treating different psychiatric conditions, including mood disorders. Recent open label trials show that psychedelics, such as ayahuasca and psilocybin, hold promise as fast-onset antidepressants in treatment-resistant patients. This presentation will discuss our recently conducted randomised placebo-controlled trial designed to further investigate the antidepressant potential of ayahuasca in patients with treatment-resistant depression. We wish to discuss the challenges and questions behind this research field, including the route and forms of administration, and the placebo effect. 

Cannabis In Natura Versus Isolated Cannabinoids: The Billion-Dollar Question of Medical Marijuana
Sidarta Ribeiro, Ph.D, UFRN/NEIP

The discovery that Cannabis contains dozens of bioactive cannabinoids, such as delta-9-tetrahydrocannabinol (D-9-THC) and cannabidiol (CBD), motivated in recent years a strong corporative push for the adoption of these purified compounds as the golden standard for medical practice involving cannabis. According to this point of view, only the use of purified cannabinoids can allow for safe and effective medical treatment. On the other hand, people around the world already benefit from medical marijuana as a whole plant (more specifically, the flower). This presentation will address this debate by 1) a review of the often opposite physiological effects of cannabinoids (e.g. delta-9-THC and CBD); 2) a presentation of the physiological notion of “entourage effect”, through which the combination of multiple cannabinoids may potentiate clinical efficacy while attenuating side effects; 3) a discussion of the potential advantages and disadvantages of therapeutics based on cannabis in natura versus purified compounds; 4) a discussion of the major economic and social implications of this debate; and 5) a general reflection on the philosophical implications and divides between the concepts of “plants” and “compounds”, both for users and science.

The Placebo Paradox
Katherine Hendy, Ph.D, OSU

The re-vitalization of clinical trials with psychedelics has produced an exciting new array of studies investigating different combinations of therapeutic substances and diagnoses. Beyond the important bureaucratic negotiations that have taken place to gain approval for these studies, this new wave of studies is also negotiating a new methodological landscape of clinical research. When researchers Humphry Osmond and Abram Hoffer were studying the use of hallucinogens in Saskatchewan in the 1950’s, their research was published as case studies. However, today, placebo controlled randomized controlled studies are now the standard for research with psychopharmaceuticals. Because psychedelic therapy seeks to induce a radical change in consciousness—to make a subject feel different from her everyday self—blinding theses studies has emerged as a methodological sticking point. However, this paper argues, that it is also a rich site for interrogating the paradoxes of placebo effects more generally. Anthropology has generally engaged with the placebo as inert: either as an example of the power of symbolic healing within Western medicine, or as ethically fraught territory of non-treatment. In contrast, this paper frames placebos as anything but inert; they are heavily charged with efficacy within the logic of the clinical trial. Drawing upon ethnographic research with clinical researchers from the Multidisciplinary Association for Psychedelic Studies (MAPS) and the history of the use of placebos in medicine and in research, this paper will explore how contemporary studies are negotiating the placebo paradox.

From “Teacher” to “Tool” and Back Again: Understanding Psychedelics Using a Critical Pedagogies Approach

Tehseen Noorani, Ph.D, NYU

Traditionally understood as “plant teachers,” psychedelics have been characterized as “cognitive tools” for a secular, Western milieu. In this presentation, I consider what gets lost in the translation from plant teacher to cognitive tool. What might it mean to take seriously the idea of psychedelics as plant teachers within contexts such as underground experimentation and clinical trial research? The term “plant teachers” evokes many interesting questions that run parallel to issues concerning the medicalization of psychedelic substances: Do different psychedelics have varying teaching styles? Does one psychedelic teach differently under varying sets and settings? Can educators themselves learn to emulate how psychedelics teach? Drawing on a comparative ethnography of university-based clinical research and underground experimentation with psychedelic substances, this presentation offers one formulation of psychedelic teaching, in terms of a “trickster pedagogy,” constructed out of key concepts from the field of critical pedagogy. I propose three themes for understanding how psychedelics teach: a) through an agency which inculcates mystery, b) with an authority that demands attention, and c) by forcing the rearticulation, rather than solving, of problems. Claiming that psychedelics are cognitive tools inspires a techno-utopian pursuit of individual optimization. Moreover, cognitive psychology studies that seek to categorize aspects of the psychedelic experience tend to imply that there is an automaticity to how psychedelics affect us. By contrast, considering them as plant teachers offering trickster pedagogies shifts the focus from ends to means, enabling us to harness a more radical set of capacities oriented towards egalitarian forms of participatory living.

Núcleo de Estudos Interdisciplinares sobre Psicoativos – (NEIP)

NEIP – Interdisciplinary Group for Psychoactive Studies – was founded in 2001 in Brazil. It is a group that unites scholars from various institutions in Brazil and abroad to promote reflection on the topic of psychoactive substances. Member researchers investigate diverse aspects of psychoactives, such as their religious use (ayahuasca, iboga, San Pedro and coca leaves), and secular or non-religious uses of both legal substances (alcohol, tobacco, coffee, etc.) and illegal substances (marijuana, cocaine, crack, ecstasy, etc.), as well as their therapeutic use. Its members also investigate harm reduction policies, narco-trafficking, and medical and media discourses on psychoactives. NEIP seeks to participate in public debate about drug policy, which is normally dominated by ill-informed and prejudiced perspectives, and insists that the Human Sciences have an important role to play in broadening and deepening this debate. In as far as NEIP understands contemporary international prohibitionist policy to stifle debate and reflection, it adopts an anti-prohibitionist political and ethical stance. It thus promotes simultaneously research activity, intellectual exchange, and political intervention. NEIP has built thought-out the year a huge on-line library, which offers free access to a wide variety of materials on drugs, with emphasis in psychedelics, especially ayahuasca.
