Native Americans use Peyote for Spirit Walks and if you are really interested in participating you can go to Arizona and go through the whole ceremony.
The use of hallucinogens was wide spread throughout history and across continents. In South America many tribes use a variety of hallucinogens to talk to and commune with ancestors and spirits as well as to fight demons.
The appalling thing is the ignorance to the spiritual purposes of hallucinogens to expand the consciousness in western thinking. If a religion does not involve praying to Jesus or involving Jesus it is heathenism. Even ancient Celtic tribes used hallucinogens for religious rites.
The Maori and several other Polynesian tribes as well as some South American Head hunters would get doped up on hallucinogens before going into combat. Not feeling pain was an asset in fighting. It also made them very fearless.
Most of the time the hallucinogens were derived from Mushrooms, cacti, certain plants, and tree barks.
On an odd side note did you know Aspirin originally was derived from Willow Bark?
