Adolescents who use ayahuasca in a religious setting show similar lifetime drug use compared to those who never use it, but they consume significantly less alcohol. In the previous year, 46.31% of ayahuasca-using adolescents drank alcohol versus 74.4% of the comparison group; recent alcohol use was 32.5% versus 65.1%. The findings suggest religious affiliation may protect against alcohol use, and that early exposure to ayahuasca in a controlled ritual context does not lead to broader drug misuse.

Adolescents who consume ayahuasca in a religious setting show lower rates of anxiety, body dysmorphic concerns, and attentional problems compared to matched controls, despite similar overall psychiatric profiles. The study compared 40 adolescents from a Brazilian ayahuasca sect with 40 controls matched on sex, age, and education. Screening scales for depression, anxiety, alcohol abuse, attentional problems, and body dysmorphic disorders found considerably lower positive scores for anxiety, body dysmorphism, and attentional problems among ayahuasca-using adolescents. These low frequencies may reflect a protective effect of religious affiliation, though further research on other variables is needed.

Adolescents who use ayahuasca in a religious context show no significant differences in neuropsychological performance compared to matched controls. A battery of tests measuring speeded attention, visual search, sequencing, psychomotor speed, verbal and visual abilities, memory, and mental flexibility found no impairment among ayahuasca users. The groups were matched for sex, age, and education. Statistical comparisons using independent t-tests indicated no significant differences on any measure. The authors suggest further studies are needed to confirm these findings.

In Brazil, adolescents who consume ayahuasca as part of the União do Vegetal religion appear to be healthy, thoughtful, considerate, and strongly bonded to their families and religious peers, based on qualitative comparisons with non-using peers. The study examined 28 ayahuasca-consuming teens and 28 non-users, using vignettes to measure moral and ethical concerns. The findings suggest that, within a legal, structured religious context with elder facilitation, ayahuasca-using youth do not differ from their non-using counterparts in these qualitative measures. This work helps clarify the effects of hallucinogenic plant use in a socially sanctioned setting.
