I don't know of any offhand. I have been working closely with current and past leaders of the Native American Church. Mostly, they work with peyote and not psilocybin, but there have been no reported abuses in that specific transaction.
Of course, as our other witness Lindsay mentioned, there are all sorts of other issues going on. Access to drinking water is a huge issue that overwhelms the conversations about particular drug abuses, if you will. I think that can't be taken out.
