Summary: Recent research suggests psychedelic substances such as psilocybin may offer therapeutic benefits for conditions like depression, anxiety, addiction and PTSD. Emerging work also explores how these experiences can increase people’s sense of connection to nature and, potentially, encourage greater environmental responsibility.

In recent years scientific interest in the psychological effects of psychedelic drugs has resurged. For example, clinical trials administering psilocybin to people with treatment-resistant depression have reported notable improvements that in some cases persisted for months. Such findings have strengthened confidence that psychedelics may have real therapeutic potential across a range of mental health conditions, and may also support end-of-life care.
Alongside these clinical outcomes, researchers have repeatedly observed that psychedelic experiences often bring increased feelings of connectedness—toward the self, other people and the natural world. This sense of connectedness has become a measurable construct in psychology, commonly referred to as nature connectedness. It captures not only how often someone spends time in nature but, more importantly, how much they feel part of and emotionally linked to the natural world.
One recent peer-reviewed study has drawn attention by linking these two strands of research. Using established measures of nature connectedness, the authors evaluated more than 600 participants before and after one or more psychedelic experiences. They found that psychedelic use tended to increase participants’ reported sense of being connected to nature, an effect that was stronger when the experience occurred in natural surroundings.
Psychedelics for planetary health
The study’s authors build on prior evidence that direct engagement with nature—and a felt affiliation with it—underpins environmental concern and motivates people to reduce environmentally harmful behaviours. Their provocative suggestion is that if psychedelic experiences reliably deepen nature connectedness, they could have a role not only in mental health care but also in promoting greater environmental awareness and responsibility.
Psychologically, psychedelics can produce states of self-transcendence in which the usual boundaries between self and other, or self and environment, temporarily dissolve. Participants often describe feelings of “oneness,” absorption or “oceanic boundlessness,” where the distinction between observer and observed becomes blurred. One person in a previous study put it simply: “Before I enjoyed nature, now I feel part of it. Before I was looking at it as a thing, now you’re part of it, there’s no separation or distinction, you are it.”
The implication is that such experiences can leave a powerful, lasting impression: if someone experiences themselves as part of nature, they may be more inclined to protect it. Based on this logic, the authors propose that carefully delivered psychedelic-assisted experiences in natural settings could foster deeper ecological concern and motivate pro-environmental action.
Caution: psychedelics ahead
This idea is intriguing but requires careful scrutiny. There is no single “magic pill” that will generate mass environmental responsibility. Psychedelic experiences are not a substitute for policies, structural change or targeted collective action directed at the actors and systems driving environmental harm. Focusing solely on shifting individual behaviour risks diverting attention from broader social, economic and political levers that must change to address the climate and ecological crises.
At the same time, it is valuable to consider the broader significance of these substances beyond longstanding cultural assumptions and prohibitionist policies. The clinical trials referenced above used carefully controlled doses in therapeutic contexts with trained professionals supporting participants—an important distinction from unsupervised use. When handled responsibly, profound experiences of connectedness—though not always easy or comfortable—can be transformative.
Such experiences may help counter feelings of futility and isolation that many people feel when faced with large-scale environmental degradation. By weakening the sense of being a separate, powerless individual, psychedelic-facilitated connectedness could encourage people to form social bonds, join collective efforts and perceive the systemic nature of ecological problems rather than shouldering solitary guilt.
These questions matter now because many people live increasingly separate from direct encounters with living ecosystems. Urbanisation, habitat loss and the accelerating scale of species decline create an environment of chronic grief, denial and psychological disconnection. In such a context, opportunities that rekindle an immediate, felt relationship with nature could be psychologically significant—and potentially politically energising if they prompt engagement rather than withdrawal.
Nevertheless, treating psychedelic experiences as a straightforward route to civic or political mobilisation risks oversimplifying both human psychology and the scale of the environmental crisis. Any therapeutic or ecological application would need robust evidence, ethical safeguards, culturally sensitive practices and integration into wider social and policy strategies.
In short, exploring the potential of psychedelics to deepen nature connectedness is a worthwhile line of inquiry. It challenges entrenched assumptions about drugs and their potential benefits while inviting careful, evidence-based discussion about how individual transformation might intersect with collective responses to ecological emergencies. But psychedelic-assisted experiences should be considered one possible component among many needed to foster lasting environmental stewardship and effective climate action.
