Mescaline

Mescaline is a naturally occurring psychedelic substance found in certain species of cactus, the most well-known being the peyote cactus. The effects of mescaline are similar to those of LSD.

Although peyote is a Schedule I drug, and is therefore illegal, the listing of peyote as a controlled substance does not apply to the use of peyote in religious ceremonies of the Native American Church.

Any person who manufactures peyote for or distributes peyote to the Native American Church, however, is required to obtain registration annually and to comply with all other requirements of law.
