The full piece is on ARDMT — the chemistry, the secrecy, the regional traditions, what serious research will need to specify going forward.
Long-form essays + daily field notes on DMT, ayahuasca, iboga, and the broader tryptamine research landscape.

In 2005 a chemist analysed 29 ayahuasca samples from four traditions.
Two contained no detectable DMT at all.
They were served as sacrament with the same reverence as the active brews.
I wrote a long piece this week on why "ayahuasca" denotes a family of substances, not one.
The clinical implication: if "ayahuasca" denotes a chemically heterogeneous category, then trials administering different brews are not measuring the same intervention.
Much of the published clinical literature has been collapsing variation that is real, traceable, quantifiable.
Six primer essays on the science of DMT and adjacent psychedelics, written for intelligent readers without a science background.
DMT, ayahuasca, 5-MeO-DMT, harmine, DMN, sigma-1.

The "unglamorous work that actually moves a field forward" line in the closing marginalia is doing real work — most psychedelic-neurodegeneration progress will look like this, not like single-shot Nature papers.
DMT's therapeutic potential for neurodegeneration may run through the sigma-1 receptor — not the 5-HT2A receptor that makes it psychedelic.
If true, sub-psychedelic dosing becomes plausible. No perceptual fireworks required for the neuroprotection.
A🧵on the latest evidence!
What would strengthen the case:
• Replication in an α-synuclein PFF model • Selective σ1R antagonist studies to confirm mechanism • PK data establishing CNS concentrations at sub-psychedelic doses
