People of color in North America report improvements in racial trauma and mental health symptoms following psychedelic experiences
Open accessAbstract
This study examined how psychedelics reduced symptoms of racial trauma among black, indigenous, and people of color (BIPOC) subsequent to an experience of racism. A cross-sectional internet-based survey included questions about experiences with racism, mental health symptoms, and acute and enduring psychedelic effects. Changes in mental health were assessed by retrospective report of symptoms in the 30 days before and 30 days after an experience with psilocybin, Lysergic acid diethylamide (LSD), or 3,4-Methylenedioxymethamphetamine (MDMA). We recruited 313 diverse BIPOC in the US and Canada. Results revealed a significant (p < .001) and moderate (d = −.45) reduction in traumatic stress symptoms from before-to-after the psychedelic experience. Similarly, participants reported decreases in depression (p < .001; d = −.52), anxiety (p < .001; d = −.53), and stress (p < .001; d = −.32). There was also a significant relationship (Rc = 0.52, p < .001) between the dimension of acute psychedelic effects (mystical-type, insight, and challenging experiences) and decreases in a cluster of subsequent psychopathology (traumatic stress, depression, anxiety, and stress), while controlling for the frequency of prior discrimination and the time since the psychedelic experience. BIPOC have been underrepresented in psychedelic studies. Psychedelics may decrease the negative impact of racial trauma. Future studies should examine the efficacy of psychedelic-assisted therapy for individuals with a history of race-based trauma.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
