There is a rather remarkable religious group known as the Temple of the True Inner Light, in New York City, which has embraced as its Eucharist DPT which they refer to as a powerful Angel of the Host. Their communion is confirmed by either the smoking or the drinking of the sacrament, and they have been totally unbothered by any agency of the Federal Government, as far as I know.
It is not as if they were unknown. Quite on the contrary, I had on one occasion received a request for information on the drug from a reporter who was writing a story on DPT and its use in the church. I asked him just how he had gotten my name, and he told me that he was given it by someone within the DEA. Someone, sometime, should write an essay on contemporary religions, as to why DPT has flown, why peyote forever struggles, and LSD and marijuana have bombed out, when tied to religion.
Is there something about a faith being an "approved" religion? Who gives his approval? Who decides the applicability of the first amendment which explicitly states that, "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof."
