In a 2026 study, Joanna Kuc and colleagues at UCL analysed daily voice journals from 29 experienced participants for two weeks before and two weeks after a single 5-MeO-DMT session at a retreat. The researchers examined language and acoustic features. The study was small, had no control group and does not show that the session caused the differences they observed.
Two things stood out.
The first is the method. Instead of relying only on questionnaires at a clinic, the study collected short entries in participants’ own words. Within this sample, the researchers reported differences in language before and after the session, including more language about participants’ own experience. Those associations need replication and should not be used to assess an individual.
The second finding concerned preparation. In this sample, some pre-session language features were associated with scores on a preparedness measure. Other findings, including acoustic features and associations with emotional breakthrough, were exploratory. They are not diagnostic signals and do not establish that a particular way of speaking makes someone ready.
What Reweave does differently
Reweave uses regular check-ins to record what a participant reports over time. It does not analyse voice, infer preparedness from language or turn answers into a headline integration score. This study does not validate Reweave or show that repeated check-ins improve an outcome.
Reweave begins after the experience. If you already have a note or voice recording from beforehand, it may be one account to compare with what you notice now. The note you wrote before explains how to do that without treating it as a prediction.
The transferable idea is modest: a short private voice note may be a practical way to record an observation. The acoustic and language models remain research, not user-facing or clinical signals.
Why the 5-MeO-DMT programme stays specific
Because all participants attended a 5-MeO-DMT retreat, the results should not be assumed to apply to other substances, settings or people. Reweave has a separate 5-MeO-DMT programme alongside the psilocybin programme.
Reweave is education and structured reflection, not therapy, crisis care or medical advice. Reweave does not charge for its crisis routes or put them behind a sale. External phone, data or service charges may still apply.
