These rituals have always been sacraments for pre-Hispanic cultures and religions; as such, in the past couple of decades they have been legalized in both Mexico and the USA.

These ayahuasca or peyote retreats announce their retreats in social media, I know this happens in New Mexico, California and Baja California, surely other states in both countries also have these weekend retreats, but I’ve personally never been to one of these.
What I have been doing is practicing daily meditation for the past seven years, I haven’t really felt the call yet to partake in an ayahuasca ritual.
