In a double‑blind, placebo‑controlled study, healthy adults received four repeated low doses of LSD (13 or 26 μg) at 3–4‑day intervals. The 26 μg dose produced modest subjective drug effects but neither dose improved mood or cognitive/emotional task performance, no residual effects were detected at follow‑up, and the regimen was well tolerated in this controlled, limited‑administration setting.
