Subjective Effects and Characteristics of Salvia Divinorum Use from a Retrospective Largescale Survey

June 26, 2026 Spencer W. Wheeler, Jonathan Dinsmore, Natalie L. Dyer preprint

Salvia divinorum is a unique psychedelic whose active compound, salvinorin A, acts on kappa opioid receptors. In an online survey of 321 participants about their most recent salvia experience, the average number of items endorsed on the Salvia Experience Checklist (SEC) was 16.5 out of 58, and the average Hallucinogen Rating Scale (HRS) score was 186.36. Scores on all HRS subscales correlated significantly with SEC scores. Exploratory factor analysis of the SEC yielded 10 factors, and content analysis identified 16 major themes. Higher SEC scores were associated with stronger extract potency and with smoking as the administration method. The findings help characterize salvia's phenomenology and support further development of the SEC.

Changes in biofield measures and experienced states during meditation and breathwork practices: an uncontrolled feasibility study

Frontiers in Psychology February 25, 2026 Natalie L. Dyer, Meredith Sprengel, Ivo V. Stuldreher et al.

A feasibility study monitored 23 adults with multiple sensors during guided loving kindness meditation and breathwork. Biofield measures changed as expected for some participants. After meditation, participants reported lower arousal and increased control, boundarylessness, and non-duality. After breathwork, participants reported increased arousal and decreased boundarylessness, connectedness, and non-duality. Strong correlations (r > 0.5) appeared between ultraweak photon emission from both hands, and moderate correlations (r > 0.4) between infrared nose temperature and left hand ultraweak photon emission. The authors conclude that simultaneous multi-sensor monitoring is feasible and that meditation and breathwork produce nearly opposite effects, but larger samples and control groups are needed.
