Ayahuasca: Beyond the Amazon – Risks and Challenges of a Spreading Tradition

<strong>By Stephen Trichter, Psy.D.</strong>

The increasing popularity of ayahuasca among Western spiritual seekers, due to its reputation for creating profound spiritual and mystical states of consciousness, has created a necessity to examine how to integrate these spiritual healing rituals into Western concepts of psychological health and ethical conduct. As the use of ayahuasca shifts to use outside of its original cultural context, we must examine how the spread of this healing practice can not only bring the benefits for which it was originally intended, but how its transfer into a new cultural framework potentially can also cause distress and harm.

Given the many research findings related to the use of ayahuasca, from finding no physical or psychological harm in chronic use (Callaway et al., 1999; Riba & Barbanoj, 2005), to its benefits in spiritual inquiry and psychological growth (Dobkin de Rios et al., 2005; Doering-Silveira et al., 2005; Grob et al., 1996; Hoffmann, Keppel-Hesselink, & da Silveira Barbosa 2001; Naranjo 1979; Shanon 2002; Trichter, 2006; Trichter et al., 2009), it is of no wonder that increased attention is being given to the brew by Western researchers and seekers alike. Despite these findings and extensive anecdotal reports of healing and transformation, there is concern about how this growing phenomenon could harm those Westerners who partake in the ayahuasca brew, unless guidelines are created to protect their physical, psychological and spiritual health.

The movement of ayahuasca rituals from an Amazonian cultural context to a Western one creates the potential for serious risks to participants as this movement gains popularity in the West. It is only within the Amazonian indigenous cultures and syncretic Brazilian churches in which power hierarchies and traditional family-community structure exist that the current models of ayahuasca ritual have thrived. Although there are many aspects of these rituals that would benefit Westerners, it is important to realize how differences in culture are likely to require an adaptation and evolution when applied to new settings.

In a detailed look into what is happening in “ayahuasca tourism,” Dobkin de Rios and Rumrrill (2008) pointed to the health of Western users who participate in an unregulated and economically challenged Amazon region where charlatans and malevolent practitioners use the hallucinogenic brew to take advantage of high paying Western ayahuasca tourists.

Although their work and similar findings contain important contributions to the literature, I take the position that a significant number of more subtle, yet equally harmful psychological risks are involved in integrating ayahuasca-based rituals into Western contexts, even if knowledgeable, trained and respected ceremony leaders are the ones sharing the brew. Ayahuasca rituals over the centuries have adapted to their indigenous cultural context to best serve those communities. With a rapidly growing diversity of people participating in these rituals, the slow refining process used to best suit the people and communities involved is not possible. With the import of the ayahuasca trade to North America, Europe and Australia, those participating in these ceremonies, even with well intentioned and trained ayahuasca ritual leaders, are at risk of harm.

Psychiatric and medical risks

Because of the increased consumption of ayahuasca in the West, there is a need to acknowledge the medical, psychiatric, and psychological, risks involved in mixing the psychoactive chemicals of the brew. Psychiatric risks include the risks of combining ayahuasca with prescription medications, particularly the SSRI anti-depressants (Callaway & Grob, 1998). In addition, individuals diagnosed with a mental health disorder or at high risk for one are taking a potent psychedelic and are putting themselves at risk for decompensation and the potential for mental and emotional stress. Experiences can bring up past traumas or can bring about new traumatic experiences that participants may not be able have the ego strength or emotional capabilities to work through without causing significant disturbances to themselves, their friends, and their families. Further research is needed in identifying the risks and benefits of different populations, including healthy populations, neurotic patients, and psychotic patients. This kind of experience is not for everyone, just as any psychospiritual practice may not be a good match for everyone. The hallucinogenic properties of the brew allow the ego’s defenses to lower, facilitating investigation into oneself; however, this scenario can induce a rush of fear and paranoia, and psychotic states can result. Therefore it is suggested that only healthy people would find the most value participating in an ayahuasca ceremony. Determining who can safely participate in these ayahuasca rituals will continually need to be re-addressed as further research is conducted.

Spiritual Risk

In a time of postmodern and New Age hodgepodge spirituality in which Westerners often reject their Judeo-Christian past, and end up picking and choosing from different religious and mystical traditions to create an idiosyncratic spirituality, it is of great importance that the implications of introducing such a powerful shamanic tool into the West are examined. Often spiritual seekers, in an effort to escape their own psychological challenges and traumas of their past, turn towards spirituality to find answers. Roberts (2001) explained that a “genuine encounter with the Ultimate does not guarantee a genuine spirituality. The experience may be authentic, but how authentic their spirituality wasdepends on what those who had the experience do with it” (p. xii). John Welwood (2000), in his examination of the Eastern religious movement into the West termed the phenomenon “spiritual bypass,” explored the idea that people often turn to and get absorbed into an unhealthy relationship with spirituality to avoid examining their psychological issues.

Welwood’s concern about spiritual bypass expresses the sentiment that we are only successful at finding psychological health if we truly unravel our unhealthy personality patterns and/or have a history of positive psychological development. Participating in an ayahuasca ceremony in and of itself creates a risk of falling into old patterns, newly masked. This idea flies in the face of many of those who blindly rush towards the potential spiritual and psychological benefits discussed earlier. As Welwood illuminated, much has been learned from the challenges of the movement of Eastern religions to the West that those seeking enlightenment in ashrams and on mountaintops may sometimes merely push their pain into the unconscious while donning a shiny new spiritual practice veneer. Immersing oneself in a community based on ayahuasca rituals can create many similar blind spots to self-growth and well-being.

Furthermore, one must acknowledge the possibility that spiritual seekers who pursue ayahuasca rituals may be looking for answers to some of their life’s challenges in the bottom of a glass of a hallucinogenic tea. While studies (MacRae, 1992; Sulla, 2005; Trichter, 2006; Villaescusa, 2002) have shown that profound insights are possible during ayahuasca ceremonies, there are no studies of Westerners to date that show that these insights can be integrated into the patient’s ongoing life in order to make the positive changes they are seeking. With no ongoing treatment or continuity of care, not only might patients find it difficult to integrate these insights into their life, but if the ceremony breaks down psychological defenses and results in opening up trauma that is left unresolved, these patients are at risk of developing new or exacerbating old psychological difficulties.

Through my clinical work, I have discovered that many Western participants in ayahuasca ceremonies seek out the weekend long spiritual retreats typical in the West, for similar reasons that Fotiou (2010) has found in shamanic tourism – for self transformation, healing, accessing the sacred, etc. They end up depending on the retreats for this type of environment and seek out ceremonies during which they may connect to the medicine, sometimes several dozen times per year. As discussed elsewhere in more detail (Trichter, 2009) and seen through my clinical work with patients, some of these individuals often find themselves coming back for more insights, connection with alleged spirits, and alleged spiritual healing in a compulsive way. This ceremony-craving behavior is the result of a co-dependence on the ayahuasca rituals and its components, which is a form of what could be called spiritual addiction. It is a way in which the person uses an external object as a soothing coping mechanism. This will likely fail repeatedly as the patient will become psychologically dependent on the ayahuasca to achieve these visions, feelings, and insights.

Despite the sense of connection that I previously reported in many ayahuasca ceremony participants (Trichter, 2006), I have observed in some patients in my clinical practice a sense of spiritual narcissism, a phenomenon similar to Welwood’s (2000) observations when eastern religions moved to the West. Individuals become so deeply involved in the spiritual path with the ceremonies that they become unaware of the impact of their spiritual pursuits. Through my clinical practice I have observed participants who do not have compassion for others who do not share the ideology of the community. Other people have pushed aside their life’s work and their loved ones in order to spend more time drinking ayahuasca in ceremony to connect with what they consider to be “the spirit world.”

Ethical and Legal Challenges

One of the greatest challenges of the movement of ayahuasca culture to the West is the movement of a tradition rooted in psychoactive substances and shamanic community leaders to ones with vastly different contemporary and historical cultural values. In a risk similar to the challenges of adopting Eastern guru-based practices in the West (Kornfield, 1993; Welwood, 2000), the ayahuasca ritual leader’s position of power in combination with the psychoactive brew can create many challenges. Ayahuasqueros are in the center of power, of psychoactive substances, and of wealthy and devoted participants who often see the brew as a means of connecting with the Divine. This often leads to participants who idealize the shamanic practitioner, sometimes falling in love and occasionally developing a sexual relationship with him or her.

The interpersonal dynamics and energy between the practitioner who is conducting an ayahuasca ritual and the participant can cause significant harm in the participant when not handled appropriately. Ayahuasca ceremony leaders often come from other Amazonian cultural traditions and are rarely trained in the knowledge of transference and countertransference issues — terms used in psychotherapy to describe the unconscious projections of energy between patient and therapist. This knowledge is necessary in order for ayahuasca ritual leaders to navigate these powerful energies within a culturally appropriate Western framework.

As discussed in more detail elsewhere (Trichter, 2009), it is not uncommon that well-established and seasoned ayahuasca ritual leaders demonstrate countertransference towards the participants in their circles. The ayahuasqueros may end up superimposing their own agenda on the client, claiming that the client needs to go through certain types of intense experiences, some of them sexual in nature. Some ritual leaders have been known to project erotic fantasies into their work with participants. Although often not consciously wielding their power over the participants in drug induced states, sexual relationships are quite common between healers and participants during rituals and sometimes continue on an ongoing basis.

Strong feelings of the ayahuasca ritual leader can emerge in other ways as well. Leaders can be supportive or punishing towards certain of the participants’ reactions to their action, the effects of the brew, or the ceremony in general. Ritual leaders may project their feelings of anger, disappointment, shame, or guilt onto participants if they do not act according to expectations. Clients can also idealize the leaders losing their original intention for participating in the rituals by focusing more attention and energy on the leader than on their own growth and development (Kornfield, 1993).

Regardless of the setting, ayahuasca leaders have been known to be attached to certain ideologies and dogmas that are entwined in their traditions. It is often in these cases that ceremony leaders with little understanding of how their own personal reactions can be psychologically harmful to the participants can do a great disservice to those they attempt to heal.

Within the Western framework of psychological healing, the therapist creates a safe container by examining his or her countertransference issues and keeping any idiosyncratic or impulsive feelings from entering the room or the group. A well-developed theory regarding how the ayahuasca ceremony leader relates to participants as part of the healing process would be useful in this exploration. Otherwise, without this relational agreement, negative results can occur, causing pain to the participant. For example, if the ceremony leader prefers hearing about one type of experience and not another, then the result becomes conditioned, and little, if any, growth can occur.

A final consideration involves the regulation of ayahuasca. In the countries of the Amazon (principally Brazil, Peru, and Ecuador), the use of ayahuasca, whether in the indigenous context or in the religious contexts described earlier, is legal. In the Western world, the situation is not clear. Although UDV’s right to use ayahuasca has been affirmed by the U.S. Supreme Court, Dimethyltryptamine, in itself, remains a Schedule I substance in the United States, which makes it illegal for administration and consumption (Bullis, 2008).

Regardless of whether or not there is ambiguous legal status there are no standards (or protocol) of how ayahuasca ceremonies are to be safely and effectively conducted, nor any ethical guidelines for how ayahuasca ceremony leaders should work with their participants in any country. There are many disparate ceremony leaders from various cultural traditions, and different schools of thought, each with idiosyncratic variations on ceremonies that make standards and regulations of ayahuasca ceremonies and ceremony leaders’ conduct difficult, if not impossible, to maintain. Furthermore, because of the great variability within ayahuasca ceremonies and ceremony leaders right now, there is no current protocol on how ayahuasca ceremonies could be integrated as a beneficial part of psychotherapy, counseling, or spiritual development.



The growing evidence of the positive benefits of drinking ayahuasca has led to a surge in use from its original base in South America to ritual leaders traveling worldwide conducting ceremonies with the brew. However, these benefits do not come without serious risks involved. There are many precautions that should be taken on order to insure the protection of ayahuasca ritual participants as this indigenous shamanic tradition makes its way into the Western world. The following list is by no means exhaustive, as it is not meant to make recommendations beyond the author’s field of expertise.


It is of increasing importance that the public needs to be educated about the traditional use of ayahuasca in both church and indigenous settings, so that they can be well-informed about making a decision whether or not to participate in these rituals. Too often participants blindly trust ayahuasca ritual leaders and place their medical and psychological well-being into the hands of strangers. The growing body of knowledge gathered by seasoned ayahuasca communities and academia needs to be utilized to educate naïve newcomers about the psychological and spiritual risks and benefits of working with ayahuasca. Creating a cross-cultural document about the medical risks involved in contraindicated medicines and foods and sharing the document with pertinent forums and centers could prevent unnecessary hospitalizations and deaths.

Additionally, by educating those interested in participating in ayahuasca rituals regarding the traditional uses of the brew, the cultures in which the rituals originated and the cosmology of the traditions, there would likely be an increase in seriousness, reverence, structure, and cohesive community support with contemporary rituals. Simultaneously, education of this sort would likely decrease the use of ayahuasca ritual as “spiritual recreation,” as well as the number of unskilled leaders who are not prepared to handle the challenges that manifest during ceremonies.

Psychotherapeutic Integration

By combining ayahuasca rituals with Western psychotherapeutic models, participation in these traditions could be brought towards a healthy Western psychospiritual healing practice. Takiwasi, a center that combines ayahuasca and other indigenous healing tools with psychotherapy, is one such model that has been treating patients suffering from severe drug addiction for the past 25 years in Tarapoto, Peru (Mabit, 2007). Through such integration, the psychological health of participants could be safeguarded so that during psychotherapy sessions they could explore potential spiritual bypass and investigate shame or guilt that may have come up in transference-countertransference issues within the ayahuasca ritual context. Standing alone, the ayahuasca ceremony has the potential of creating meaningful and significant mystical and spiritual states of being; however, combined with psychotherapy, specific qualities of such states can further promote the essential goals that have been proven to be effective in the Western psychotherapeutic modalities.

Another benefit of integrating psychotherapy and ayahuasca rituals is that it would allow licensed and experienced mental health professionals to help screen, prepare potential crisis intervention, and work with emerging traumas and post-ceremony integration. The work that can be done with an experienced licensed mental health professional begins with preparing the client with the potential of emotionally challenging material that may come up during the ceremonies. The clinician can also work with the client to prepare an intention as a focusing of the client’s psychospiritual needs at the time of the ceremony. Doing so may enable the client to guide the direction of the experience towards gaining insights into pertinent areas that are challenging the client’s presenting problem or development.

To achieve the greatest benefit from an ayahuasca ceremony, it would be valuable for the client to have participated in therapy for some time. One of the key benefits that could be found in integrating psychotherapy and an ayahuasca ritual would be that the previous therapeutic work could be brought into the ayahuasca ritual for further investigation, the experiences could be further explored, and the interpretation’s validity tested in the dream-like states of the ayahuasca experience.

The client could prepare for the ayahuasca ritual work by setting an intention to further explore themes that have come up during therapy and could examine any resistance recognized in the consultation room during the ceremony. The clients who might be working on several themes in their ongoing therapy could determine with appropriately trained clinicians which ones might be most effectively explored during an ayahuasca ritual.

During ayahuasca rituals it would be valuable to have a well-trained clinician available for participants who were overwhelmed, agitated, and/or unstable during the experience. It is possible for participants in ayahuasca ceremony to be in crisis due to fear and anxiety over the altered state of consciousness or the psychological material that comes up. One major psychological service that can be employed during these ceremonies is having people trained in crisis intervention available. Often in the Western context, ceremonies have “sitters” assisting participants who are confused or disoriented. Sitters could be trained in relaxation techniques, empathic listening, and simply being present to alleviate some of the stressors that occur during these crises.

Few sitters are trained in mental health procedures and many are inadequately able to assist the participants or work with the client to use the psychological material that is coming up for the client to their benefit. In the traditional ayahuasca context, the ritual leader, or ayahuasquero uses icaros (songs), native tobacco, and other shamanic tools to assist the struggling participant (Luna, 1986). However, this is part of a larger context of community support found in the traditional culture. Although these tools can and should be utilized in the ceremony, it is not unheard of that individuals sometime seek more Western-oriented tools to aid in the process during ceremony. A clinician trained in integrating spirituality and psychotherapy, is helpful to have on hand to help individuals work through their experience if needed in the moment.

Most contemporary psychotherapeutic frameworks state that a therapeutic relationship is necessary for the client to experience sincere relatedness to others and to develop a stronger sense of oneself. Therefore, the sense of interconnectedness that participants feel with this type of work could be supplemented with such psychotherapeutic techniques to create complementary benefits (Shanon 2002; Trichter, 2006). Although the sense of connection sometimes felt during experiences with ayahuasca can have healing benefits for participants, there is often no ongoing concrete relationship that is deliberately occurring during the group rituals. This causes questions of the sustainable impact of these feelings on contemporary Western psyche. By bringing the feelings of connection to a therapeutic relationship alongside participation in an ayahuasca ritual, they could be further explored and integrated.

The integration of ayahuasca ceremony into a framework of ongoing psychotherapy would create a greater sense of safety for the client when participating in an ayahuasca ritual. This would allow the participant to explore a situation that often brings up fear, feeling fully prepared. It would also allow the client to share his or her experiences with the therapist post-ceremony. Lastly, this rapport would create an opportunity for the therapist to make interpretations more freely while the ceremony experience is more temporally and affectively grounded within the client. After participating in the ceremony, the affective experiences and the insights that may have been obtained through the ayahuasca ritual could be interpreted, worked through, and integrated into the ongoing therapy.

In order to avoid the pitfalls of spiritual bypass, numbing distraction, and egocentric self involvement (Welwood, 2000), it is valuable for a trained clinician to work with the participants of the ayahuasca ceremony afterwards in order to help them use the material to interface with their intentions, spiritual growth, interpersonal connections, and psychological development. Welwood’s concern about spiritual bypass expresses sentiments similar to the psychotherapy model which states that we are only successful at finding health if we link affective expression and interpersonal connection with reality, not fantasy (Mitchell, 1993). When clients participate in an ayahuasca ceremony, psychotherapy creates an opportunity for the therapist and client to work through any of the breakthroughs that occurred during the ceremony to explore whether they are founded in fantasy or reality. As ayahuasca rituals are transferred into a Western culture that does not automatically support them, a means of integration is needed in order for clients to take the lessons from the ritual and incorporate them into their daily life. Because these rituals only happen sporadically in the West and the ritual leaders are often traveling between communities, there is often a feeling of longing for the next opportunity to connect with the experiences attached to earlier ayahuasca experiences. By exploring the insights, wisdom, and healing that have come out of ayahuasca ritual experiences regularly in psychotherapy, the feelings of connection, growth, strength, will, and purpose that are often reported can not only be integrated, but a tendency for dependence on the ayahuasca rituals for such states can be extinguished.

Ethical Guidelines

In addition to education and integration into Western psychotherapy, individuals would be protected from potential risks if ayahuasca ritual communities created ethical guidelines stating the proper use of the sacrament and conduct of participants and ceremony leaders. The educational movement and the collaboration with mental health professionals will only be possible through building communities and community networks to share knowledge and set standards of care during ayahuasca rituals. This is a departure from the rivalry that is commonplace between ayahuasqueros in the indigenous setting, where shamans speak badly of each other and are sometimes involved in combative sorcery (Dobkin de Rios & Rumrrill, 2008). The building of these collaborative relationships between Western communities and the ayahuasca ritual leaders with whom they work will allow proper dissemination of the educational materials, as well as medical and psychological screening standards.

Ayahuasca ritual leaders in the Western setting need to be held accountable for these outcomes because if they are not embedded in a community in which there is a continuum of feedback and accountability, they can take advantage of and abuse ritual participants and continue on to their next destination unchecked. In a similar vein to Dobkin de Rios and Rumrrill’s (2008) work, I am proposing that by setting up intra and intercommunity dialogue around ethics and monitoring the reputations of different ritual leaders the community can be protected from predators. Those ritual leaders who need to work on issues that come up with Westerners can receive the feedback they need in order to obtain further training or do personal work. Kornfield (1993) writes that Eastern religion teachers in the West had “to deal with the underlying roots of problems in themselves, whether old wounds, cultural and family history, isolation, addiction, or their own grandiosity. In some communities masters have ended up attending AA meetings or seeking counseling. In others, decision-making councils were formed to end the isolation of the teacher” (p. 264).

Setting up ethics for the communities and ayahuasca ritual leaders also would be beneficial so that the powerful temptations of power, sex, and money can be discussed transparently and leaders could be held accountable. Currently, there are no cross-cultural ethical standards by which ayahuasca ritual leaders must abide. They receive no coursework in ethics, nor are they required or advised to go through any type of personal psychotherapy, consultation, or supervision to examine any personal issues that may come up in the work they conduct.

Some groups have already begun to explore this idea such as the Montreal chapter of the Santo Daime (Ceu do Montreal Santo Daime Church of Canada, 2008) and the Indigenous Doctors Union Yageceros of the Colombian Amazon (Unión de Médicos Indigenas Yageceros de la Amazonia Colombiana, 1999). The UDV also has a 50 year tradition of monitoring the ethical conducts of their leaders (mestres) (Henman, 1986; Luís Fernando Tófoli, personal communication, February 6, 2011). More dialogue needs to be created not only within communities, but between communities so that those seeking guidance and healing from this plant medicine are adequately protected when entering such powerful and vulnerable states of consciousness.

Dobkin de Rios and Rumrrill (2008) make a strong case for the dangers involved in working with inexperienced or charlatan neo-shamans, those who have not studied the depths of the tradition and are solely seeking money, sex, and/or power. Although their investigation is extensive, there is an equally important need for the examination of well established and respected ayahuasqueros and other ayahuasca ritual leaders, whose practices and/or personal beliefs may be in conflict with participants from urban or international cultures, thus causing unintended harm to their patients. A well-developed theory regarding how the ayahuasca ceremony leader relates to participants as part of the healing process would be useful in the exploration of transference and counter-transference issues. If the participant knows that their emotions are accepted within the therapeutic relationship, the client can move from the fantasy that they have been holding onto – that affective expression yields pain and tension – to a realistic observation that connection with others through affective expression can exist.

In this global age it is no longer acceptable to claim naiveté or tradition when intentionally crossing cultural boundaries as a healer. Until we begin to look at all of these challenges in detail, the full range of potential benefits cannot be considered inside a vacuum. The community of those who participate in ayahuasca rituals must take it upon themselves to protect themselves as individuals and a community from potential harms so that they can explore the depth and beauty of the healing potential of the sacred brew.

The Author


Stephen Trichter is a licensed psychologist in private practice, a candidate at the Psychoanalytic Institute of Northern California in San Francisco, and an adjunct professor at Alliant University. In addition to working with his patients and teaching future psychologists, he is currently interested in how meditative dream states can be effectively integrated into the analytic relationship.








  1. I don’t have time to write a longer assessment of this article, but i just want to say that i appreciate it very much; and i concur whole heartedly in the importance of understanding the risks involved in working with Ayahuasca. It is an extraordinary plant, no doubt. But it does not serve the purpose of true healing to deify it, or leave unexamined its cultural context and the potential hazards that come with it. A tool is only as effective as the person that uses it. So it is with Ayahuasca.

    Epiphanies come and go; the “real” acid test is how well such experiences are integrated in daily life. I’ve heard people express that one Ayahuasca ceremony was equal to ten years of therapy. I thought the same thing once. Nonsense! the other side of the equation is not addressed in this kind of hyperbole. It does not take into account perhaps the most important thing: Integration.

    I appreciate your insights.
    Best Wishes,

  2. thank you for making this inquiry. i have worked with ayahuasca for several years and agree, it is a very challenging relationship. i have only witnessed sacred use, but your willingness to ask these questions shows great concern for many, and i appreciate that.

    ayahuasca can open your heart and show you the truth, if the truth is what you are willing to see, but it asks a lot of you, full understanding and forgiveness of oneself, which does not come easy. and, it can be painful to be in relationships with others in your life who do not understand what you have experienced. absolutely, you can add a new challenging dynamic, but i am not sure that is necessarily a negative aspect. it is a visionary medicine, so there is no alleged insight ~ insight is the pathway. whether one believes a plant is speaking to them, or the divine mother, it is a complicated spiritual convergence that one will be readied for even if they are not ready. to say that we must adhere to the cultural guidelines of nations who have long abandoned indigenous truth is difficult for me. i might instead offer that ayahuasca has expanded its reach because we are as a people are willing to risk this deeper understanding for a chance to save our souls. it is a gamble.

    i absolutely agree, ayahuasca, like any “practice” can hide you further from the truth. but it does so in a very unique way. i say unique, because the medicine is inquisitive, like your writings here, so the truth will always find its way through, eventually. there is something to be said for sitting on top of a mountain by yourself finding peace in all that is when the world around you appears to be content in mind-sucking-disdain-for-healing-hearts. The view is beautiful up there, and it feels good. I am not so sure that we need to avoid feeling good. That sensation gives us a lot of hope to work with, and to ultimately share with those in our lives.

    But to find that good feeling, we have to find that total trust in being true to our truest nature, and if we get there, and can accept others for their truest nature, then we are getting somewhere. I am not sure that is what the purpose of ayahuasca was in its early form. So perhaps this evolution of how “she” meets the “west” has already begun, through the medicine herself.

    We shall see.

  3. I have been thinking about the article for several hours now.
    At first I agreed with all of it, then I went deeper and realised I can’t go along with the notion of integration.
    There are some experiences with the medicine that are so ‘other’, so different from our everyday reality that there is no way they can be integrated.
    Case in point: Four years ago I completely left my body for a while and met the Godhead, the Etheric Christ and the Archangel Michael.
    I have never been able to integrate this experience into my everyday life and I am probably much the same individual as previously, but I would say that it has radically shifted my spiritual outlook as to the reality of supersensible beings and hence my entire cosmology.
    Neither 25 years of meditation practice nor any of the psychotherapy I have done have afforded the insights I have received during the years I have worked with the sacred plants.

    I am writing an article for an alternative journal on the significance of community in Dietas and Ayahuasca ceremony. I am looking for historical data that addresses this question and if the ceremony was always done with multiple participants, as it is most commonly seen now, and if so, why?

    Any help or direction to specific literature would be greatly appreciated and handled with the utmost discretion.

    Thank you

    Thank you for this informative article. I recently participated in a sham ceremony that left me feeling cheated and used. As much research I did before the ceremony did not prepare me for the impact of the unsafe environment. I feel that more accountability should be required, and a kind of system whereby people could check who is ‘safe’ and who is not, would profoundly help the situation.

    Nobody died from ayahuasca but from medications, a lot. Maybe it’s time to reconsider the 100 years old “modern” medicine and get closer to what people are doing for thousands of years. But this might not be in accordance to pharmaceutical industry! I would say that it is a matter of choice and no state should take responsability for taking decisions for the people benefit. It is an individual right !
