§ 04 — SCIENCE

1Fe-LSD emerged as a novel research chemical following the scheduling of other lysergamides like 1P-LSD. There is currently a complete absence of formal pharmacological, toxicological, or clinical studies on 1Fe-LSD in humans or animals. Its effects, duration, and safety profile are extrapolated entirely from anecdotal reports and its structural similarity to LSD and other N-acyl lysergamides. The pharmacokinetic data, including onset and half-life, are estimated based on the known properties of LSD and similar prodrugs.
