    A harm reduction course for facilitators in non-traditional contexts

    Over the past five years, ICEERS has collaborated with a multitude of guides, facilitators, sitters, researchers, psychologists, and doctors to gather better practices to reduce risks and increase the safety and ethics of ayahuasca ceremonies in non-traditional contexts.

    We poured everything we learned into this course to reduce risks and enhance safety of ceremonial plant work.

    The Ayahuasca Defense Fund

    Addressing the challenges presented by the growing criminalization of ayahuasca and other Traditional Indigenous Medicines

    The ADF’s network is comprised of drug policy experts, lawyers, legal strategists, and renowned academics. ADF offers information to lawyers, court case defendants, and the general public with the aim of being an expert resource for legal proceedings. The program also works to engage policymakers, law enforcement authorities, and relevant actors to move towards sensible, human rights-based public policy.

    Legal Status Map

    At the national levels there is a widespread divergence of interpretation of how international legal frameworks should be to ayahuasca. In order to avoid risks, it is important to know the specific legal situation of each country.

    Frequently Asked Questions

    Since 2010, the International Center for Ethnobotanical Education, Research, and Service (ICEERS) has led efforts to evolve the relationship of Western societies with traditional plant medicines and the cultures they are part of. Our goal is a future in which ceremonial plant work is recognized and can be safely and legally practiced while being in right relationship with the Indigenous knowledge holders. ICEERS collaborates with plant medicine community representatives, Indigenous leaders, government agencies, law enforcement, and NGOs. Alliance building is imperative to develop successful strategies to guarantee the health, safety, and fundamental rights of all communities involved.

    If you want to learn more about our organization, you can find further information here.

    ICEERS is comprised of a multidisciplinary team with extensive experience in fields such as pharmacology, law, political science, psychology, communications, human rights, anthropology, among others. Our team is made up of people with six doctorates and 16 master’s degrees. We collaborate with universities, hospitals, associations, foundations, consortiums, governmental institutions, and Indigenous groups. Learn more about our collaborators and sponsors.

    “Ethnobotany” is the science that studies the relationship between human cultures and plants. It can also refer to the knowledge that different cultures have acquired over time about the properties of various botanicals. In addition, psychoactive plant species with a longstanding relationship with different cultures are considered “ethnobotanicals”. Nearly 60% of modern medicines, from aspirin to the first anesthesia, originate from traditional medicinal plants. In fact, many of the components of today’s drugs are based on natural products that humans have worked with for centuries or millennia. Although science has only recently begun to take an interest in plants such as iboga or ayahuasca, their long standing relationship with humanity supports the essential fact that when humans have worked with plants for centuries, it is generally because they are considered “effective.” 

    No. ICEERS specifically warns against using ethnobotanicals when it violates the law, practices are conducted without proper professional guidance and/or supervision, or careful personal evaluation of the potential hazards and risks is lacking. The information provided by ICEERS is in no way intended to encourage the use of ethnobotanicals. You can find more information in the footer of this website and in Point 5.1 of the terms of use page.

    No. ICEERS never endorses or recommends any ethnobotanical center or facilitator. We do not offer psychoactive plant experiences, nor do we recommend centers or professionals offering sessions or retreats. This is clearly stated on our contact page, as well as on other parts of our website here and here. As a harm reduction strategy, we provide psychoactive plant information and a free good practices guide so that people can make their own choices and learn how to mitigate risks.

    No, ICEERS is not a membership-based organization. ICEERS is a private, non-profit foundation with United Nations consultative status (ECOSOC). We are not an association.
