LSD & Trauma / PTSD

An annotated bibliography of the research on lysergic acid diethylamide as it relates to post-traumatic stress — the clinical evidence, the mechanisms proposed to explain it, the safety signals, and the history. Cornerstone works are annotated first; the context shelf and the historical section are expanding.

A note on what this bibliography shows. Searching the literature for "LSD and PTSD" returns a hundred-plus results, but very few center LSD, and fewer still report LSD given for trauma. The modern psychedelic-PTSD evidence is dominated by MDMA and ketamine; direct LSD-for-PTSD trials essentially do not yet exist. The strongest LSD-specific clinical signal comes from the Swiss compassionate-use programme and a single controlled anxiety trial. That absence is not a gap in this bibliography — it is the finding, and it is where the open questions live.

Historical section

In progress

A hand-curated section on the 1950s–70s LSD-psychotherapy era (Eisner, Kast, Savage, Chandler, Grof) that today's search tools miss, plus a note on Traumatic neuroses in Vietnam returnees (1973) — a paper that named combat trauma before the PTSD diagnosis existed. Being built by hand; the automated watcher won't surface these.

Cornerstone annotations, the LSD-in-people and comparator links above, and this historical section deepen weekly. New publications surfaced automatically, added once verified.
