N-Morpholinyllysergamide (LSM-775) is a compound derived from ergine. While it is not as potent as LSD, it is known to induce LSD-like effects within a dosage range of 75 to 700 micrograms, albeit with a shorter duration of action. Notably, LSM-775 is associated with fewer indications of cardiovascular stimulation and peripheral toxicity when compared to LSD.
