What was said

"The recidivism rate or the return to prison rate in the ayahuasca-exposed individuals was statistically significantly lower than the recidivism rate in the control group, suggesting that, you know, whatever is going on there seems to have an effect on whatever drives criminal behavior."

Dr. Williams described Brazilian research in which prisoners who received ayahuasca sessions showed statistically lower rates of returning to prison compared to control groups. The study utilized ayahuasca's status as a Catholic sacrament in some Brazilian sects, though Williams cautioned against interpreting this as a recommendation for widespread prison psychedelic use.
