The present work focuses on the indemnity issues that pervade the Pantheistic Society Ayahuasca, based in Pernambuco, considering that these identities are multiple and fluctuating in the context of postmodernity. Within this perspective, using the ethnographic method and interviews, it also seeks to analyze issues related to the ritual and how individuals signify the use of ayahuasca in their lives. From an anti-prohibitionist perspective on the use of psychoactive agents, it is worth that the ritual demarcates a place, where the members' coexistence and mutual assistance during the experience are edifying means for the individuals who use the substance. In addition, he realizes that the use of psychoactive agents is built through a triad: drug, set and setting. The identity issues are, in turn, brought with the understanding of the different meanings given to the concept of what pantheism is, based on the philosophy of Baruch Spinoza and Regis Allain Barbier, founder of the group. Such philosophical and theological parameters serve as a guide for the positioning of members who embrace an eco-humanist, monist cause, which has its main inspiration in Nature.
