Brava Theater Center, 2781 24th St, San Francisco, California

April 25 and 26 2020, 9 am to 6 pm

This Summit will bring together experts from around the world to discuss the legal, cultural, and political issues around the emerging psychedelic renaissance. Efforts to decriminalize or legalize psychedelics have picked up steam around the United States, with Denver recently decriminalizing psilocybin mushrooms and Oakland decriminalizing all natural psychedelics. In addition, advocates in Oregon are planning a statewide ballot initiative to regulate psilocybin in 2020. The topics addressed will include: the process of applying for religious exemptions with the DEA; psilocybin decriminalization initiatives; the right to ameliorate pain and suffering; cognitive liberty; drug use and human rights; ibogaine bills; the upcoming FDA regulation of MDMA and psilocybin; psychedelic harm reduction; licensed health care providers and psychedelic-assisted therapy; the paradoxes of cannabis regulation and NIDA monopoly for research cannabis; conservation of endangered species; human’s relationship to sacred plants and nature; the continuities and discontinuities between recreational, therapeutic and religious use of drugs; the future legal markets; and the commercialization of psychedelics. The Summit aims to discuss the future of psychedelic practices in the US, including decriminalization, legalization, and medicalization. Finally, Chacruna will officially launch the Council for the Protection of Sacred Plants at the Summit. The Council is an initiative of the Chacruna Institute that advocates for the legality of sacred plant medicines among indigenous peoples and non-indigenous communities, encourages legal harm-reduction practices that protect those who use them, educates about conservation of plant species, documents relevant legal and social issues, and consults on legal cases.

Dawn D. Davis – Habitat Loss, Decriminalization, Conservation and Legalization Frameworks of Peyote 

The peyote cactus [Lophophora williamsii],which is ingested for its medicinal qualities, has been a conservation concern for peyotists and members of the Native American Church (NAC) since 1976. Since 2009, the International Union for the Conservation of Nature has identified peyote as a vulnerable species across its range within the United States and Mexico.  The primary threat to long-term conservation is overharvesting due to increased demands by members of the NAC, in addition to improper harvesting techniques of peyote distributors, and large-scale land conversion. This presentation includes not only an examination of the spatial distribution of peyote as it relates to course scale fragmentation of habitat; it will also discuss the intersection of decriminalization, legalization, and conservation. Inclusion of an Indigenous ecological perspective in these conversations allows for inter-Tribal and community-based conservation, co-management, and enactment of sacred ecology. It is important that peyote, as it relates to a bona fide religion recognized by the Supreme Court of the United States, is acknowledged and afforded respect. 

Sean McAllister – Denver Psilocybin Initiative: Update on Implementation and Implication for Future Psychedelic Decriminalization Initiatives

Sean will review the strategy behind the campaign that decriminalized psilocybin mushrooms in the city of Denver. He will discuss the ongoing issues with its implementation, including the impacts of the Denver Psilocybin decriminalization campaign on public safety and health. As a member of the Denver Psilocybin Review Panel, he will assess the Review Panel’s work and recommendations regarding psilocybin policy going forward. Implementation issues consisting of educating police and the City Attorney’s Office on personal possession limits for psilocybin, monitoring arrests, carrying out the Psilocybin Review Panel with City Officials, and public education campaigns around harm reduction and psilocybin will be analyzed. Next, Sean will assess the current status of the Decriminalize California campaign and contrast the various efforts to decriminalize psychedelics around the country. Finally, Sean will discuss the many lessons from cannabis legalization that apply to psychedelic campaigns. In particular, Sean will review the advantages and disadvantages of decriminalization initiatives, and contrast the Denver model with other initiatives.

Kevin Feeney – Peyote as Commodity: An Examination of Market Actors and Access Mechanisms

Access to the peyote cactus, a religious sacrament of the Native American Church (NAC), has been regulated since 1965. However, during the last 40 years, the regulated peyote market has shown signs of decline despite reported growth in NAC membership during the same period. This market decline raises questions about the ecological impacts of harvesting practices, as well as levels of consumption of a very limited natural resource. Protecting access to peyote for NAC religious practices and conserving the viability of natural peyote populations are both important goals; goals that should be addressed simultaneously, if possible. In order to determine whether biological, economic, regulatory, or other factors are responsible for the decline in the regulated peyote trade, Access Theory is used to map the various commodity chains that make up the peyote supply network and to identify the primary factors responsible for reduced access to this sacrament. Avenues for bolstering access deficiencies in the peyote supply network are considered, as well as some possible conservation options.

Brad A. Bartlett – Religious Exercise and Controlled Substances: Navigating the U.S. Legal Framework for Sacramental Use of Psychedelics 

There are hundreds of groups using ayahuasca in ceremonial contexts in the United States, and many more exercising a brand of therapeutic and mystical uses of psilocybin, peyote, and Sonora Desert toad serum. They all dream of future legalization and the ability to use psychedelics as a religious sacrament or in the exercise of religious activities without fear of criminal prosecution. However, currently, only a handful of religious adherents have received exemptions to U.S. criminal prohibitions on psychedelics. This presentation will discuss legal mechanisms the U.S. government has in place for such situations; a rather complicated scenario that, as currently constituted, seemingly disfavors religious free exercise. Specifically, the author will focus on the history of religious exercise vis-à-vis controlled substances, current policies of the Drug Enforcement Administration requiring petitioning and registration by religious adherents, and possible reforms to the current legal framework.

Jag Davis – Psychedelics and the War on Drugs: What Can We Learn from Cannabis Legalization and Other Social Justice Movements?

How do we account for the multi-generational, ongoing harms of psychedelic criminalization—and how do we begin to repair those harms? In what ways does the War on Drugs continue to drastically limit the scope of scientific research? What are some of the key limitations of the medical model for psychedelics? Where do efforts to decriminalize psychedelics fit within the broader context of criminal justice and public health reform, especially current campaigns to implement Portugal-style drug decriminalization? How can we best maximize the effectiveness of emerging psychedelics-specific policy reform efforts? What can we learn from cannabis legalization and other recent criminal justice reforms? What are some viable non-commercialized models for legalization, such as Spain’s cooperative social clubs for cannabis? What are the strategic and ethical risks of psychedelics “exceptionalism”? How can we ensure that psychedelics aren’t just profitable and legally accessible for a privileged few; all while poor, black, brown, and indigenous people involved with psychedelics continue to be socioeconomically marginalized and harshly criminalized?

Matthew W. Johnson – The Controlled Substances Act, and the Path of Medical Psilocybin Approval

Ongoing research suggests the potential safety and efficacy of psilocybin for several psychiatric disorders. If Phase III research shows safety and efficacy for one of these disorders, this will prompt the potential movement of psilocybin away from its current placement in Schedule I, which is the most restrictive classification and allows for no medical use. This talk will review the 8 factors that inform scheduling decisions under the US Controlled Substances Act (CSA). The talk will review empirical research on psilocybin relevant to each of these 8 factors. This review generally concludes that psilocybin has limited abuse liability. While its use sometimes results in identified harms, the prevalence of harms is considerably lower than for many other scheduled and legal substances of abuse. Moreover, evidence suggests use rates are typically low, and that psilocybin lacks a classic addiction profile. The data suggests that if psilocybin is approved for medical use based on Phase III research, its appropriate placement would be in Schedule IV of the CSA. However, additional safeguards should be provided by the FDA’s framework of Risk Evaluation and Mitigation Strategies (REMS), including the need to use under professional supervision rather than take-home use. Importantly, these recommendations are relevant to medical development of psilocybin under the current CSA framework, notwithstanding the empirically demonstrated civil rights problems and public health harms associated with a criminal system approach to addressing drug harms.

Kufikiri Imara – Decriminalization in Oakland: A One Year Retrospective on Outreach, Education, & Access

This presentation will speak to the experiences of a local, grassroots collective in Oakland that managed to pass the June 4th 2019 resolution to decriminalize access to working with entheogenic plants and is influencing the course of drug decriminalization efforts in different cities across the country. The benefits that decriminalization offers of a shorter, cheaper, and more accessible path to working with entheogenic plants will be highlighted in his presentation. Next, he will provide a snapshot of the current status, ongoing progress, and challenges in Oakland following the city council’s unanimous vote of approval. A few of the central topics to the movement will be presented, such as: What are the impacts of the resolution language? What are the intentions and specific actions emerging from Oakland City Council and the Decriminalize Nature Oakland group? What is the mandate of Decriminalize Nature Oakland’s “Outreach, Education and Access” committee? What are some specific recent and next actions coming from Oakland in this area? What challenges have emerged and how are they being addressed? How can you get involved? This will be a great opportunity to learn from Decriminalize Nature Oakland’s experience at the heart of this transformative decriminalization and educational movement.
