Which substance is lawful for nondrug use in bona fide religious ceremonies of the American Indian Church?

The correct answer is Peyote, which is a cactus containing the psychoactive substance mescaline. Within the context of bona fide religious ceremonies of the American Indian Church, the use of peyote is legally protected under the American Indian Religious Freedom Act. This act recognizes the importance of peyote as a traditional sacrament for various Native American religious practices, allowing its use during ceremonial events without legal repercussions typically associated with controlled substances.

While other substances like LSD, psilocybin, and marijuana may have religious or cultural significance, they do not enjoy the same legal protections or recognition for use in religious ceremonies under current U.S. law. Peyote is specifically mentioned in legal contexts regarding Native American religious practices, confirming its accepted status within those traditions.
