    Summary PsychonautWiki

    Lysergic acid morpholide (also known as N-Morpholinyllysergamide, and LSM-775) is a novel synthetic research psychedelic of the lysergamide chemical class that produces a generally similar albeit significantly less psychoactive array of LSD-like psychedelic effects when administered. It is a close structural homolog of LSD known mainly for its obscurity, low relative potency, and a few comments that have been made on the "dream-like" sedation it produces as well as potential nausea and other potentially uncomfortable physical effects.
