What is the Native American Church and why is peyote sacred to members?

The Native American Church is considered the most widespread religious movement among the Indigenous people of North America. It holds sacred the peyote cactus, which grows naturally only in some parts of southern Texas and northern Mexico. Peyote has been used spiritually in ceremonies, and as a medicine by Native American people for millennia. It contains several psychoactive compounds, primarily mescaline, which is a hallucinogen. Different tribes of peyote people have their own name for the cactus.
