ICEERS launched the Integration Training Program to disseminate the expertise gathered from its Support Center, which has helped more than a thousand people with integration questions over the last 10 years.
In contrast to other programs currently on the market, the ICEERS Integration Program is unique in its practical approach. This course is designed to provide you with the framework to design and implement an integration protocol. You will learn techniques and tools that will increase your capacity to support people in their integration processes.
The key to a collective healing revolution does not lie in the renaissance of substances, but in the renaissance of relationship. Our relationship with ourselves, each other, Indigenous peoples, and Life itself.
The core of our work is to weave relationships of trust and alliance among plant medicine and psychedelic community representatives, Indigenous leaders, academic experts, global change makers, and government agencies – bringing our collective wealth of knowledge(s) and experience together.
”There is no power for change greater than a community discovering what it cares about.”

The ICEERS Academy “Increasing the Safety of Ayahuasca Sessions” course offers a unique perspective on safe and responsible practices around ayahuasca and other ancestral medicines. This advanced harm reduction program is designed for facilitators, participants, plant ceremony organizers, and anyone else interested in ceremonial and traditional plant practices. The curriculum provides the necessary tools to ensure safe sessions while respecting ethical principles and safeguarding the well-being of participants.
The course lasts six months and provides access to health forms, emergency protocols, guides, and other documents to reduce risks and increase the safety of ayahuasca sessions.
Registration is open until May 1st.
We have co-hosted spaces for dialogue and community building, including international conferences, expert strategy meetings, and working groups. We have built strategic alliances with Indigenous partners with the goal of unifying people and knowledge(s) together through shared objectives.
Our Legal Defense Program (ADF) has supported over 300 legal cases in 45 countries through legal advice, technical reports, and expert witnesses.
Our Support Center has provided crisis support to over 1,200 people in need and our Medical Interactions Service fields inquiries about interactions between plants medicines, pharmaceutical drugs, and medical treatments.
ICEERS works to pollinate a network of support for local and international plant medicine communities that is internationally coordinated and publicly funded as an essential service – accessible to anyone in need.
We provide evidence-based, real-world information on ayahuasca, iboga, and other ethnobotanical practices. We also examine their globalization — safety, ethics, legality, policy, science, and more — based on information gathered from the global community. This work includes technical reports, articles, manuscripts, webinars, trainings, a risk reduction course for ayahuasca facilitators, and integration training for mental health professionals.
In collaboration with international research teams, we have published more than 100 papers in top-tier peer-reviewed journals and books. These scientific papers have served as a basis for legal proceedings and advocacy work across the globe. We are also conducting the world’s first ibogaine clinical trial for opioid dependency in a pioneering harm reduction center in Catalonia.
We have organized and participated in over 20 United Nations processes and events, including the UN’s International Guidelines on Human Rights and Drug Policy. We authored important bills for policymakers in different countries in the European Union and Latin America, and engaged in national policy processes that are changing the future of ethnobotanicals.
On the weekend of May 24 and 25, 2025, the third edition of La Seta Crítica was held in the Sierra de Guadarrama, in Madrid. This alternative gathering, organized by Kravan and the Madrid Psychedelic Society, is already establishing itself as a landmark event for those who explore the social, therapeutic, cultural, and spiritual dimensions of entheogens.
How does the consumption of cannabinoids affect our ability to understand and relate to others? Is our emotional perception altered? Or do our social skills remain intact? What differences exist between THC and CBD?
With the increase in practices with psychoactive plants, the number of people facing difficult experiences is also growing. For more than a decade, ICEERS’ El Faro Support Center has offered a safe, free and confidential space to accompany these processes.
This study reexamines data from the Global Ayahuasca Survey, which included 10,836 participants who reported on their experiences with ayahuasca, a traditional Amazonian psychoactive brew.
This chapter adopts a transdisciplinary approach to explore the concept of psychedelic integration, considering its various contexts ranging from clinical trials to Neo-shamanic, traditional, and recreational settings.
The article examines the potential role of ayahuasca communities within the Compassionate Communities movement, which aims to support individuals and families during end-of-life care and bereavement.
This chapter explores the growing global expansion of practices involving psychoactive plants, such as ayahuasca, iboga, and psilocybin mushrooms.
The study explores the associations between ayahuasca use in naturalistic settings and mental health and wellbeing, utilizing a dataset of 7,576 participants from over 50 countries.
The study provides a comprehensive review of over a decade of research conducted by ICEERS, focusing on how ayahuasca is embedded in traditional Amazonian medicine and its increasing global relevance.
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.

“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.
