Lysergic acid ethylamide (LAE-32 orLAE) is apsychedelic drug of thelysergamide family related tolysergic acid diethylamide (LSD).[1][2] It is reported to have someLSD-like effects but is weaker and shorter lasting, with an active dose reported to be between 0.5 and 1.4 mg.[1][3]

It was studied by theCIA as part ofProject MKULTRA. Documents published by the CIA under theFreedom of Information Act suggest it causes "a schizophrenia-like condition" but it allows people withschizophrenia to remain indifferent to their disorder.[citation needed] The drug has also been studied inpsychedelic-assisted psychotherapy.[3]

LAE-32 was first described in thescientific literature byAlbert Hofmann and colleagues by 1955.[4] It is not acontrolled substance inCanada as of 2025.[5]

In an Italian study (not included in Table 2), Franco Giberti and Luciano Gregoretti compared 12 patients with 'conversion disorder' in 2–8 weekly sessions of psycholytic therapy with 100 µg LSD and 1–2 weekly sessions with 500 µg of LAE-32 (another LSD analogue that is weaker and shorter-lasting) with 14 patients with obsessive compulsive disorder (OCD). During the dosing sessions, the patients with 'conversion disorder' showed amplification of sensory and motor impairment; however, in some cases showed 'miraculous' improvement.49 Unfortunately, the authors did not provide outcome data for the patients, rendering this follow up unsuitable for further analysis.
