Key findings Regular ayahuasca use was associated with lower anxiety, less negative affect, higher intrinsic religiosity, and less past-month licit and illicit drug use compared to non-regular use.

Abstract

Background: Preliminary evidence suggests that long-term ayahuasca use is associated with better psychosocial outcomes and less drug use; however, available data on the association between ayahuasca intake frequency and psychosocial outcomes is limited.

Objectives: We sought to characterize and investigate the association of regular ayahuasca use, as compared to non-regular use, on licit (alcohol and tobacco) and illicit (cannabis, psychostimulants, psychedelics, and non-medical opioids) drug use and psychosocial outcomes.

Methods: An online-based cross-sectional survey was taken among people who use ayahuasca in Brazil assessing sociodemographic, drug and ayahuasca use, anxiety and depression (HAD-S), intrinsic religiosity (IRI), negative and positive affects (PANAS), satisfaction with life (SWLS), and five quality of life domains (WHOQOL-Brief). Multivariate regressions for each psychosocial outcome and drug use were performed comparing regular to non-regular ayahuasca users while correcting for sociodemographic variables.

Results: A total of 286 valid answers were retrieved, divided into people with regular (n = 101) and non-regular (n = 185) ayahuasca use. Groups had similar sociodemographic profiles and lifetime use of drugs. In the multivariate analysis, regular use of ayahuasca was associated with lower anxiety (B: -0.97), negative affect (B: -2.62), general (B: 0.22) and physical (B: 0.17) quality of life, higher intrinsic religiosity scores (B: 4.16), and less past-month licit (OR = 0.30) and illicit (OR = 0.49) use of substances.

Conclusions: Our results show that ceremonial regular ayahuasca compared to non-regular use is associated with better psychosocial and mental health outcomes and less drug use. Studies with repeated ayahuasca administration and extended follow-ups are essential to clarify the nature of ayahuasca's therapeutic effects and to guide future clinical research.
