Therapeutic Potential Ascribed to Ayahuasca by Users in the Czech Republic

The study employed qualitative fieldwork approved by the authors’ institutional ethics board. Initial recruitment began with a pilot anonymous online questionnaire in July–August 2015 that contacted 1,452 people linked to ayahuasca interest groups on social media; from respondents the team purposively recruited 46 volunteers for in‑depth interviews. Fieldwork and interviews were conducted in the Czech Republic between November 2015 and December 2016. All participants gave informed consent and identifying details were anonymised. The final sample comprised 46 people (23 women, 23 men) who had taken part at least once in an ayahuasca ceremony or served as facilitators; nine were ceremonial leaders and 37 were participants. The sample had a mean age of 34.5 years (sd = 11.8) and varied educationally and occupationally; most (91.3%) were Czech nationals. The investigators note that the illegality of DMT‑containing preparations in the Czech Republic influenced recruitment, and that the intended sample of up to 35 was increased to reach data saturation. Data collection used semi‑structured interviews that were audio recorded and manually transcribed. The authors analysed transcripts using the Grounded Theory Method, a qualitative approach for developing theory from data by iterative coding. Seven researchers from diverse disciplines (anthropology, psychology, religious studies, international relations) participated in data collection and transcription to support triangulation. Transcripts (46 files totalling about 1,044 standard pages) were coded in three phases—open, axial and selective coding—to generate analytical categories and a coding frame that was refined during analysis.

Findings are presented as users’ perceptions and illustrative narratives generated via Grounded Theory analysis. A central theme was that the subjective intensity of an ayahuasca session did not necessarily predict therapeutic benefit; several participants reported meaningful, lasting change even when their acute experience felt weak. Many informants described ayahuasca as having broad, even ‘‘cure‑all’’ potential, and they attributed benefits across psychological and physical domains. Depression and psychological blocks were commonly cited targets. One participant (a professional soldier) claimed strong benefit for depression and for ‘‘negative view of life,’’ and some users reported relief from chronic physical pain following ceremonies. Addiction treatment emerged as a prominent perceived application: several participants with histories of alcohol, heroin or tobacco dependence described long‑term reductions in craving and improvements in coping. For example, one informant reported that after several ceremonies cravings for alcohol and other drugs had ceased and that symptoms such as tremor and paranoia had resolved, improving work and private life functioning. Others credited the ritual and associated dietary rules and purging (vomiting) with helping them stop smoking or reduce caffeine use. Respondents suggested mechanisms for therapeutic change centred on memory recall and emotional processing. Participants described vivid retrieval of past events, including childhood or traumatic memories, which they felt could be examined and integrated. A ritual organiser invoked transgenerational and multilayered memory levels as therapeutic targets. The sample narratives also emphasised the role of ritual context, diet and integration practices in shaping outcomes. The paper notes that only a limited set of illustrative narratives could be included due to space constraints, and that the results reflect participants’ subjective accounts rather than clinical measurement.

The investigators interpret their findings cautiously, emphasising that user testimonies indicate perceived, sometimes long‑lasting, therapeutic effects but that these claims require further empirical support. They argue that clinical trials would be necessary before ayahuasca could be accepted as a medication, and they highlight legal and institutional barriers in the Czech Republic where DMT‑containing preparations are illegal. Questions remain about the duration of any therapeutic effects, and the authors call for future research to specify how long benefits persist. Context dependence and integration receive particular attention: users commonly conceptualised ayahuasca as a ‘‘panacea,’’ but the authors warn that such a label can be misleading and potentially harmful for vulnerable people. They contend that therapeutic outcomes likely depend on factors such as ceremonial setting, facilitator experience, dietary practices and subsequent integration or psychotherapeutic work, and they recommend that methods of integration be studied and reported in detail. The discussion also raises concerns about commodification and ‘‘ayahuasca tourism,’’ noting risks when rituals are conducted by under‑prepared facilitators or appropriated outside traditional contexts. Finally, the authors acknowledge limits to generalisability: the study is based on self‑reports from a purposive sample in a legal grey zone, and the total number of users in the country cannot be quantified due to illegality and informal networks. These constraints, they state, justify cautious interpretation and further research.

Horák and colleagues draw four primary theoretical implications from user testimonies. First, the perceived therapeutic benefit of ayahuasca is not directly proportional to the acute intensity of the experience and may endure beyond the session. Second, many users regarded ayahuasca as having broad, ‘‘cure‑all’’ potential, though the authors do not endorse that claim. Third, respondents commonly identified addiction treatment—reduction of craving and improved coping with stress—as a key therapeutic application, echoing prior studies. Fourth, they propose that a likely mechanism is memory recall: ayahuasca may activate suppressed or forgotten mental contents that require later integration through belief systems or psychotherapeutic approaches, for example those derived from depth psychology.
