Ayahuasca use and reported effects on depression and anxiety symptoms: an international cross-sectional study of 11,912 consumers
Open accessAbstract
Ayahuasca is a psychoactive Amazonian brew which has emerging data indicating that it has antidepressant and anxiolytic properties. This paper uses data from the Global Ayahuasca Project (GAP), which was undertaken across 2017–2020 and involved 11912 people, to examine the perceived effects of Ayahuasca consumption on affective symptoms. The study focused on the subsample reporting depression or anxiety diagnoses at time of Ayahuasca consumption. Of participants reporting depression (n = 1571) or anxiety (n = 1125) at the time of consuming Ayahuasca, 78% reported that their depression was either ‘very much’ improved (46%), or ‘completely resolved’ (32%); while 70% of those with anxiety reported that their symptoms were ‘very much’ improved (54%), or ‘completely resolved’ (16%). A range of factors were associated with greater reported affective symptoms improvement, including subjective mystical experience, number of Ayahuasca sessions, and number of personal psychological insights experienced. 2.7% and 4.5% of drinkers with depression or anxiety, respectively, reported worsening of symptoms. This study is recognized as a cross-sectional analysis which cannot assess treatment efficacy. Selection bias may exist due to survey-respondents with favorable experience being potentially biased towards participation. Drinkers of Ayahuasca in naturalistic settings perceived remarkable benefits for their affective symptoms in this survey assessment. There is no obvious evidence of negative mental health effects being associated with long-term consumption. Additional randomized controlled trial evidence is required to establish the efficacy of Ayahuasca in affective disorders, and to understand the worsened symptoms reported by a small percentage of drinkers.

Converging evidence from preclinical and human studies suggests oral formulations of DMT such as ayahuasca show potential in reducing anxiety, depressive symptoms, addictive behaviors, and posttraumatic distress.
“Indeed, converging evidence from preclinical and human studies suggest that oral formulations of DMT such as ayahuasca show potential in reducing anxiety, depressive symptoms, addictive behaviors, and posttraumatic distress (1–3, 30–35).”

The Introduction describes human studies reporting antidepressant and anti-addictive effects of ayahuasca, and the Discussion reports self-perceived improvements in anxiety and depression. Our copy does not report a reduction in posttraumatic distress, so it supports only part of the cited sentence. (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
