Lysergic acid ethylamide (LAE-32 or LAE), also known as N-ethyllysergamide, is a psychedelic drug of the lysergamide family related to lysergic acid diethylamide (LSD). It is the analogue of LSD in which one of the ethyl groups on the amide moiety has been removed.
The drug is reported to have some LSD-like effects but is weaker and shorter-lasting, with an active dose reported to be between 0.5 and 1.6mg by different routes of administration including subcutaneous or intramuscular injection and oral administration. Side effects like apathy and sedation have been reported.
Analogues of LAE-32 include LSD, MLA-74 (1-methyl-LAE), ALA-10 (1-acetyl-LAE; 1A-LAE), lysergic acid methylamide (LAM), lysergic acid propylamide (LAP), LME-54 (lysergic acid methylethylamide), and LEP-57 (lysergic acid ethylpropylamide; EPLA), among others.
LAE-32 was first described in the scientific literature by Albert Hofmann and colleagues by 1955. It was studied by the CIA as part of Project MKULTRA. Documents published by the CIA under the Freedom of Information Act suggest it causes "a schizophrenia-like condition" but it allows people with schizophrenia to remain indifferent to their disorder. The drug has also been studied in psychedelic-assisted psychotherapy. It is not a controlled substance in Canada as of 2025.

Total: 4 hrs – 10 hrsHow It Feels
The experience of LAE-32 is an exercise in subtlety. If most psychedelics are a thunderstorm, this is a shift in barometric pressure: something has changed in the atmosphere, but you would be hard pressed to point to exactly what. The onset creeps in over thirty to forty-five minutes with an almost imperceptible lightening of mood and a vague sense that the edges of perception have been gently softened.
Physically, there is very little to report. Perhaps a mild warmth in the chest, a faint increase in heart rate, a barely noticeable enhancement of tactile sensitivity. The body remains comfortable and grounded, unburdened by the tension, nausea, or stimulation that accompany more potent lysergamides. You could walk through a grocery store on LAE-32 and no one, least of all you, would suspect anything remarkable was occurring.
The peak, such as it is, manifests as a gentle heightening of aesthetic sensitivity. Colors appear marginally more vivid, music becomes slightly more emotionally engaging, and there is a mild increase in the fluidity of thought. Creative associations come a fraction more easily. There may be the faintest suggestion of visual enhancement, a barely perceptible wavering at the edges of patterned surfaces, but nothing that could be called a hallucination by any honest accounting. The cognitive effects are equally restrained: a mild introspective tendency, an increased capacity for focused attention, and perhaps a slight loosening of habitual thought patterns.
The offset is so gradual as to be almost indistinguishable from the natural fluctuations of daily consciousness. After three to four hours you may realize that whatever gentle alteration was present has simply dissolved. There is no comedown, no crash, no residual stimulation. LAE-32 leaves almost no experiential footprint, and its primary value lies in demonstrating just how minimal a lysergamide experience can be while still registering as psychoactive at all.
Subjective Effects
The effects listed below are based on the Subjective Effect Index (SEI), an open research literature based on anecdotal reports and personal analyses. They should be viewed with a healthy degree of skepticism. These effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects.

Pharmacology
LAE-32 most likely acts by binding to serotonin receptors in the brain. It may, like LSD, bind to dopamine receptors as well.
The subjective effects of LAE-32 are reportedly mainly sedating and depersonalizing, creating a state of indifference in users. -Cannabis** - Cannabis has an unexpectedly strong and somewhat unpredictable synergy with psychedelics. Extreme caution is advised when using this combination as it can significantly increase the chances of a negative psychological reaction like anxiety, confusion and psychosis. Users are advised to start off with only a fraction of their usual cannabis dose and take long breaks between hits to avoid over intake. -Amphetamines** &Cocaine - Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences. -Tramadol** - Tramadol is well known to lower seizure threshold and psychedelics also cause occasional seizures.
LAE-32 is not explicitly illegal in any nation, but it is possibly illegal to possess in the United States for purposes of consumption due to the Federal Analog Act.

Detection Methods
Urine Detection
LAE-32 and its metabolites are not targeted by standard immunoassay-based urine drug screens. Because lysergamides are active at microgram doses, the absolute quantity of drug and metabolite present in biological samples is extremely low, making detection inherently difficult. Specialized urine assays using liquid chromatography-tandem mass spectrometry (LC-MS/MS) can identify lysergamide metabolites within approximately 24 to 72 hours after ingestion, though this window is shorter than most other drug classes due to rapid metabolism and renal clearance.
Blood and Serum Detection
Blood detection windows for LAE-32 are narrow. Plasma concentrations peak within 1 to 3 hours of oral administration and fall below detectable thresholds within 6 to 12 hours for most analytical methods. LC-MS/MS can extend this window modestly, but serum testing for lysergamides is rarely performed outside of forensic or research contexts due to the specialized equipment required and the very low concentrations involved.
Standard Drug Panel Inclusion
LAE-32 is NOT included on standard 5-panel, 10-panel, or 12-panel drug screens. These panels test for amphetamines, cannabinoids, cocaine metabolites, opiates, and PCP (with extended panels adding benzodiazepines, barbiturates, and similar classes). Lysergamides do not cross-react with any of these immunoassay targets. Detection requires a specific request for lysergamide testing, which is uncommon in workplace, probationary, or emergency department screening.
Confirmatory Methods
When lysergamide use is specifically suspected, confirmatory testing relies on LC-MS/MS or gas chromatography-mass spectrometry (GC-MS). LC-MS/MS is the preferred method due to its superior sensitivity at picogram-per-milliliter concentrations. Immunoassay-based LSD-specific screens exist but suffer from high false-negative rates with novel lysergamide analogs, as antibody cross-reactivity varies between compounds.
Reagent Testing (Harm Reduction)
For harm reduction identification, the Ehrlich reagent is the primary tool for LAE-32. A small sample placed on the reagent should produce a purple to violet color change, indicating the presence of an indole moiety characteristic of lysergamides. The Hofmann reagent provides a confirmatory blue to purple reaction. Importantly, the Marquis reagent shows no reaction or a faint olive discoloration with lysergamides, which helps distinguish them from other compound classes. A positive Ehrlich result does not confirm the specific lysergamide identity but does rule out NBOMe and NBOH compounds, which show no Ehrlich reaction. Using both Ehrlich and Hofmann reagents together provides greater confidence in lysergamide identification.

History
- The CIA and Project MKULTRA Findings
LAE-32 was experimented with by the CIA as part of Project MKULTRA. It was reported to create a condition similar to that of schizophrenia in mentally healthy individuals, characterized by indifference and depersonalization. While it was reported that, when used on schizophrenics, it created a condition that allowed the patients to become indifferent to their hallucinations and cease hallucinatory excitation.
LAE-32, or d-lysergic acid ethylamide, is a semisynthetic substance of the lysergamide family.
Its chemical structure consists of a bicyclic hexahydroindole ring fused to a bicyclic quinoline group (lysergic acid). At carbon 8 of the quinoline an N, generally N-ethyl carboxamide is bound, LAE-32 is additionally substituted at carbon 6 with a methyl group.
LAE-32 most likely acts by binding to serotonin receptors in the brain. It may, like LSD, bind to dopamine receptors as well.
The subjective effects of LAE-32 are reportedly mainly sedating and depersonalizing, creating a state of indifference in users. -Cannabis** - Cannabis has an unexpectedly strong and somewhat unpredictable synergy with psychedelics.

Harm Reduction
General Principles
- Start low, go slow: Always begin with a low dose, especially with unfamiliar batches or new substances. Individual sensitivity varies enormously.
- Test your substances: Use reagent test kits to verify identity and check for dangerous adulterants. Consider using drug checking services where available.
- Research thoroughly: Understand expected dose ranges, duration, potential interactions, and contraindications before use.
- Never use alone: Have a trusted, sober person present, especially with new substances or higher doses.
- Set and setting: Your mindset and environment profoundly influence the experience. Choose a safe, comfortable environment and ensure you're in a stable psychological state.
LAE-32-Specific Harm Reduction
- Integration: Allow time between experiences to integrate insights. Using psychedelics too frequently can lead to psychological distress.
- Trip sitter: A sober, experienced sitter is invaluable, especially at higher doses. They should be briefed on what to expect and how to help.
- Difficult experiences: If anxiety occurs, change the setting (different room, different music), practice slow breathing, and remember the effects are temporary. Having a benzodiazepine available (not for routine use) can provide reassurance.
- Duration planning: Ensure you have no obligations for the full duration plus several hours of recovery time.
- Contraindications: Avoid combining with lithium (seizure risk), tramadol (seizure risk), or SSRIs (reduced effects, potential serotonin issues). Those with personal or family history of psychotic disorders should exercise extreme caution.
Toxicity & Safety
The toxicity profile of LAE-32, like most classical psychedelics, suggests a relatively favorable physiological safety margin. Classical psychedelics as a class have among the lowest organ toxicity of any psychoactive substances, with therapeutic indices far exceeding those of many common medications.
Physical toxicity: The primary physical risks associated with LAE-32 are indirect — injuries resulting from impaired judgment during the acute experience. Direct organ toxicity at typical recreational doses has not been well-established. However, the long-term effects of repeated use are not fully characterized.
Psychological risks: The more significant risks are psychological. These include acute anxiety/panic reactions ("bad trips"), triggering or exacerbating latent psychiatric conditions (particularly psychotic disorders), and Hallucinogen Persisting Perception Disorder (HPPD) — a condition involving persistent visual disturbances after use.
Serotonin syndrome: Combining LAE-32 with serotonergic medications (MAOIs, SSRIs) can elevate serotonin to dangerous levels. This interaction requires particular caution.
Dependence potential: LAE-32 is not considered physically addictive, and tolerance to psychedelic effects develops rapidly (within days), making daily use impractical. Psychological dependence, while possible, is relatively uncommon compared to other substance classes.
It is strongly recommended that one use harm reduction practices when using this substance.
Overdose Information
Fatal overdose from LAE-32 alone, at doses within the typical recreational range, is extremely unlikely based on the available evidence for classical psychedelics. The therapeutic index for most psychedelics is very wide.
However, psychological emergencies can occur and require appropriate response:
- Severe anxiety, panic, or psychotic episodes
- Dangerous behavior due to impaired reality testing
- Self-harm in the context of a distressing experience
Emergency management: If someone is experiencing a severe adverse reaction, move them to a calm, quiet environment. Speak reassuringly. Do not restrain unless there is immediate danger. Benzodiazepines (if available and the person is conscious and able to swallow) can reduce acute anxiety. If psychotic symptoms, self-harm risk, or medical distress is present, seek emergency medical attention.
Medical attention: Seek help immediately for seizures, extremely elevated body temperature, signs of serotonin syndrome (agitation, tremor, diarrhea, rapid heart rate), or if the substance consumed is uncertain.

Tips (5)
Start with a low dose of LAE-32 if it is your first time. You can always take more next time but you cannot take less once ingested. The difference between a comfortable and an overwhelming experience can be surprisingly small.
Psychedelic tolerance builds rapidly. Wait at least 1-2 weeks between uses of LAE-32 for full tolerance reset. Taking the same dose the next day would require roughly double the amount for comparable effects.
Use a milligram scale to weigh LAE-32 if it comes as a powder. Eyeballing doses of potent psychedelics is irresponsible. A quality 0.001g scale costs under $30 and could prevent a seriously overwhelming experience.
Do not combine LAE-32 with lithium (seizure risk), tramadol (seizure/serotonin syndrome risk), or cannabis at higher doses unless very experienced. Cannabis dramatically intensifies and can destabilize a psychedelic experience.
Clear your schedule for the full duration of LAE-32 plus afterglow. Do not plan any obligations, driving, or important decisions for the day. Having a time pressure or commitment hanging over you adds unnecessary anxiety.
