For the new study, the scientists used data from 4,285 people worldwide who responded to online advertisements to complete one of two 50-minute online surveys about God encounter experiences. The surveys asked participants to recall their single most memorable encounter experience with the “God of their understanding,” a “higher power,” “ultimate reality” or “an aspect or representative of God, such as an angel.” They also asked how respondents felt about their experience and whether and how it changed their lives.

About 69 percent of the participants were men, and 88 percent were white. Of those who reported using a psychedelic, 1,184 took psilocybin (“magic mushrooms”), 1,251 said they took LSD, 435 said they took ayahuasca (a plant-based brew originating with indigenous cultures in Latin America), and 606 said they took DMT (N,N-dimethyltryptamine), also a naturally occurring substance found in certain plants and animals.

Is this the study you are referring to?
