Classic Psychedelics and Human-Animal Relations

Previous research has found associations between classic psychedelic use and nature-relatedness, but the link between classic psychedelic use and human-animal relations remains largely unexplored. Using data representative of the US adult population, with regard to age, sex and ethnicity (N = 2822), this pre-registered study assessed lifetime classic psychedelic use, ego dissolution during respondents’ most intense experience using a classic psychedelic, and three measures related to human-animal relations: speciesism, animal solidarity and desire to help animals. The results showed that lifetime classic psychedelic use was negatively associated with speciesism (beta = -0.07, p = 0.002), and positively associated with animal solidarity (beta = 0.04, p = 0.041), but no association was found with desire to help animals (beta = 0.01, p = 0.542). Ego dissolution during the respondents’ most intense experience using a classic psychedelic was negatively associated with speciesism (beta = -0.17, p < 0.001), and positively associated with animal solidarity (beta = 0.18, p < 0.001) and desire to help animals (beta = 0.10, p = 0.007). The findings indicate that classic psychedelics and ego dissolution may have an impact on human-animal relations. As these results cannot demonstrate causality, however, future studies should use longitudinal research designs to further explore the potential causal link between classic psychedelic use and human-animal relations.
