Please avoid harvesting peyote in its natural habitat.
Peyote populations are rapidly declining in nature due to over-harvesting by non-indigenous peoples. As a result, it is currently a threatened species. Those who wish to consume peyote are encouraged to grow their own or use alternative mescaline-containing cactus species such as San Pedro or Peruvian Torch.
