Hi Napo. There could be such a church, however, I’m not sure whether an ayahuasca retreat there would be considered legal. If there are actual ceremonies that are not prohibited by law, it would mean that the ayahuasca there might not be a “real” ayahuasca. I’m not an American, so I’m not fully aware about the internal situation surrounding the drug there. Please let me know if you have any additional info, it would be much appreciated :)
