Recent research suggests that serotonergic psychedelics may simultaneously enhance connectedness to both social and natural worlds. This article synthesizes current evidence regarding psychedelics' effects on nature relatedness and social connectedness, examining underlying mechanisms through the framework of self-other overlap. Psychedelics appear to facilitate self-expansion through two...

Background: Past research reports a positive relationship between experience with classic serotonergic psychedelics and nature relatedness (NR). However, these studies typically do not distinguish between different psychedelic compounds, which have a unique psychopharmacology and may be used in specific contexts and with different intentions. Likewise, it is not clear whether these findings can...

Lifetime psychedelic substance use has previously been linked to nature relatedness and pro-environmental behaviour. Yet, participants’ responses to the self-report measures in these studies may have been affected by stereotypical associations or confirmation bias. We therefore re-examined this link by measuring three pro-environmental dependent variables: nature relatedness, concerns about...

Across three studies (total N = 952), we tested how self-admitted use of psychedelics and association with psychedelic culture affects the public’s evaluation of researchers’ scientific integrity and of the quality of their research. In Studies 1 and 2, we found that self-admitted substance use negatively affected people’s assessment of a fictitious researcher’s integrity (i.e. being unbiased,...

In a large-scale ( N = 1487) general population online study, we investigated the relationship between past experience with classic psychedelic substances (e.g. LSD, psilocybin, mescaline), nature relatedness, and ecological behavior (e.g. saving water, recycling). Using structural equation modeling we found that experience with classic psychedelics uniquely predicted self-reported engagement...
