An international NGO working at the intersection of plant medicines & psychedelics, human rights, science, & Indigenous knowledge.

ICEERS serves humanity by transforming society’s relationship with psychoactive plant medicines and psychedelics, while respecting and honoring their traditional, Indigenous roots. We engage with fundamental issues resulting from the globalization of ayahuasca, iboga, and other ethnobotanicals.

Founded in 2009, ICEERS has special NGO consultative status with the United Nations’ Ecosoc, is registered as a non-profit foundation, and has charitable status in Spain. 

Donations in the USA are accepted through our fiscal sponsor MAPS, who will provide you with a tax receipt.
