A review of 103 naturalistic psychedelic studies found that most used cross-sectional surveys, ayahuasca was the most studied substance (66%), and ceremonial settings were the most common context (35.9%). Sample characteristics were widely reported but varied considerably, while specific contextual details like music were often missing. The authors call for systematic reporting standards to improve the value of real-world psychedelic research alongside clinical trials.

Portuguese adults who participate in ayahuasca ceremonies report good or very good health, with lower rates of chronic disease and obesity compared to the general population. They also report greater physical activity, lower alcohol consumption, and enhanced psychological well-being. Many attribute positive lifestyle changes, reduced substance use, and less reliance on prescription medication to their ayahuasca experiences. These findings align with prior research linking ayahuasca use to health and well-being, though causal pathways remain unclear.

Psychedelic experiences may help people adopt healthier behaviors, according to a survey of 271 adults. Participants reported changes across 74 behaviors after their most impactful psychedelic experience. The most common changes were increases in contemplative practices (63%), time spent in nature (55%), and personally meaningful social activities (54%). Most changes were in a healthy direction. Higher perceived meaningfulness of the experience and having a set intention beforehand were significantly associated with overall healthy change. The study cannot establish causality but suggests that intention and meaningfulness are candidate mechanisms for how psychedelics might facilitate positive behavior change.

Psychedelic experiences may help people adopt healthier behaviors like improved diet, more exercise, and regular meditation, according to a survey of 96 practitioners working in legal and underground settings. Practitioners reported perceived positive changes in clients' contemplative practices (61.4%), time in nature (60.1%), eating patterns (56.9%), and diet and nutrition (56%). The findings suggest that practitioners often see psychedelic experiences as linked to beneficial health behavior changes, though further research is needed to confirm these results and understand their long-term sustainability.
