Over 30 million psychedelic users in the United States
Open accessAbstract
We estimated lifetime prevalence of psychedelic use (lysergic acid diethylamide (LSD), psilocybin (magic mushrooms), mescaline, and peyote) by age category using data from a 2010 US population survey of 57,873 individuals aged 12 years and older. There were approximately 32 million lifetime psychedelic users in the US in 2010; including 17% of people aged 21 to 64 years (22% of males and 12% of females). Rate of lifetime psychedelic use was greatest among people aged 30 to 34 (total 20%, including 26% of males and 15% of females).

From The revival of psilocybin between scientific excitement, evidence of efficacy, and real-world challenges (2024) · cites this paper as [97]
The Results report an estimated 21 million US residents with lifetime psilocybin use in 2010, not 21 million current users. The Discussion mentions curiosity, mystical experiences, and introspection as reasons for psychedelic use, but our copy does not report recreational use or self-medication as reasons given by psilocybin users.

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.
