“Meeting the Medicine Halfway”: Ayahuasca Ceremony Leaders’ Perspectives on Preparation and Integration Practices for Participants

Ayahuasca is a plant‑based psychotropic tea from the Amazon whose ceremonial use for therapeutic and spiritual purposes has grown outside its traditional contexts. Previous literature and clinician guidance have emphasised the importance of preparatory and integrative practices around psychedelic experiences, but little is known about how those who actually lead ayahuasca ceremonies view preparation and integration or what practices they consider helpful for promoting safety and beneficial outcomes. Callon and colleagues set out to address this gap by conducting a qualitative study of ayahuasca ceremony leaders' perspectives. Using semistructured interviews with 15 leaders who facilitated ceremonies primarily for Western participants, the study aimed to identify preparation and integration practices that leaders believe improve ceremonial outcomes and mitigate harms, and to map the key themes arising from those perspectives.

Leaders of ayahuasca ceremonies were recruited through purposive, convenience, and snowball sampling via word‑of‑mouth, social media, online discussion groups, and targeted mailing lists; the team sought variation but limited participation to those able to communicate in English. The sample comprised 15 leaders aged 30–60 years (mean 43.47, SD 8.16), with eight identifying as male, five as female, and one as two‑spirit. Educational backgrounds varied (four with baccalaureate degrees, three with some college, three with postgraduate degrees in psychology, and four with training in alternative healing); most (n = 11) were born in North America and most (n = 12) reported having trained under an experienced ceremony leader in South America. Duration of facilitation experience ranged from 2 to 20 years (mean 9.75, SD 6.25). Some leaders disclosed specific lineages (Shipibo n = 7, Mestizo n = 3, Yagé n = 1). Individuals affiliated solely with ayahuasca churches (e.g., Santo Daime) were excluded. Each participant completed a 90‑minute semistructured telephone interview derived from a prior study protocol; interviews covered beliefs about ayahuasca's therapeutic potential and practices to improve outcomes and reduce risks. Interviews were recorded, anonymised, transcribed, and verified. Interviewers had professional degrees in mental health and prior research experience relevant to ayahuasca and psychology. Data were analysed using inductive qualitative content analysis (QCA) focused on manifest content to produce a descriptive, low‑abstraction phenomenological account. Two coauthors independently extracted and coded meaning units related to preparation and integration from all transcripts, compared codes to derive categories and subcategories, wrote memos, practised reflexivity, and met regularly to resolve disagreements; final categories were refined with input from all coauthors. Data management used Dedoose Version 8.0.35. Trustworthiness criteria (credibility, transferability, dependability, confirmability, authenticity) guided analytic rigour.

Analysis produced three main categories: factors facilitating preparation, complementary modalities that support both preparation and integration, and factors facilitating integration (with a subcategory describing ineffective integration). Participant quotations were used illustratively throughout. Factors facilitating preparation: Leaders identified seven interrelated preparatory factors they perceived as promoting favourable ceremony experiences: honesty and respect; recognition and volition (an authentic desire to heal rather than curiosity or novelty seeking); readiness and willingness to engage with potentially difficult material; internal and external resources (bodily strength, psychological fortitude, and social supports); cleansing through dietary and behavioural restrictions; intention setting; and nonattachment, openness, and surrender. Many leaders emphasised candid disclosure of contraindications and adherence to preparatory guidelines; common preparatory restrictions mentioned included limiting meats, dairy, sugar, salt, alcohol, and sexual activity, avoiding intoxicants such as cannabis, and ceasing contraindicated medications (for example some antidepressants and certain supplements). Several leaders reported that long‑term pharmaceutical use could blunt or delay benefit. More than half the leaders described intention setting as central to preparation, and nearly half recommended an attitude of nonattachment and surrender to whatever the medicine reveals. A subset also stressed the value of educating participants about ayahuasca and preparatory considerations. Factors facilitating both preparation and integration — complementary modalities: Many leaders recommended adjunctive practices to augment preparation and integration. These included psychotherapy (especially by clinicians familiar with ayahuasca), contemplative practices such as meditation and mindfulness, journaling, art and creative expression, bodywork, yoga, and modalities from Chinese medicine (for example qi‑gong and tai‑chi). More than half of the leaders emphasised daily contemplative practice as particularly helpful, with meditation singled out by several as a major facilitator of therapeutic engagement during ceremonies. Journaling and nonlinguistic creative practices were cited as useful means to process and express material that may be difficult to verbalise. Factors facilitating integration: Leaders identified three primary facilitators of productive integration: time, sharing experiences, and working with insights and lessons. Many advised that participants intentionally set aside time to rest and reflect after ceremonies — some suggested extended time away from work and distractions — and approximately one third explicitly referenced taking time off to integrate. Postceremony sharing, including morning debriefs among co‑participants and connection to knowledgeable peers or community, was nearly unanimous among leaders; they stressed that discussing visions and experiences with people who understand ayahuasca helps make sense of and stabilise changes. Working with insights involved intentional reflection and translating ceremony insights into concrete life changes; leaders described good integration as the enactment of lessons in daily life. Ineffective integration was portrayed as situations where participants received clear guidance during ceremony but failed to make changes and reverted to prior maladaptive patterns. Reasons for poor integration were attributed to individual factors (lack of readiness, motivation, avoidance or ‘‘spiritual bypass’’ via repeated ceremonies) and social/structural factors (toxic or unstable home/work environments, limited social support). Leaders noted practical limits on providing longitudinal follow‑up and often left responsibility for aftercare largely to participants, while acknowledging risks when support was absent.

Callon and colleagues interpret the findings as highlighting the distinct needs of ayahuasca use outside Indigenous cultural contexts, where preparation and integration were traditionally embedded in communal life. The leaders' perspectives reinforce the contemporary psychedelic emphasis on set and setting, and indicate that participants should deliberately create time and space for both preparation and postceremony integration. Readiness, honest disclosure, respect for ayahuasca as a medicine, and motivation to change were presented as important determinants of outcome, a view the authors link to broader psychotherapy literature on stages of change and motivation. Social support emerged as a central theme for safe and productive integration; leaders argued that community and knowledgeable peers help participants process challenging material and translate insights into sustained changes. The endorsement of complementary modalities — notably contemplative practices and psychotherapy — suggests an integrative model that draws on both ceremonial knowledge and psychotherapy practices. The authors suggest these leader perspectives could inform retreat centres, ceremony staff, and clinicians about candidate selection, participant education, and aftercare, and argue for developing consensus‑informed, evidence‑based or promising practices for preparation and integration. The authors acknowledge several limitations. The sample was modest, recruited by convenience methods, and limited to English‑speaking leaders, many of whom were non‑Indigenous and working with Western participants; therefore findings may not generalise to Indigenous practices or broader populations. The semistructured interview protocol did not specifically target preparation and integration (only one question explicitly addressed integration), and reliance on a single data source (interviews) may have limited the depth of description. Legal sensitivities may also have constrained disclosure. For future research the authors recommend studies that include ceremony participants, family members, psychotherapists, and medical practitioners; observational or clinical designs that document and evaluate differing preparation and integration approaches; ethnographic work at retreat centres; and attention to safety issues such as medication withdrawal, MAOI‑food interactions (tyramine), and best practices for medical and psychological screening.
