1-Valeroyl-d-lysergic acid diethylamide (also known as 1V-LSD or Valerie) is a novel psychedelic substance of the lysergamide class.
1V-LSD is closely related to LSD and 1P-LSD and is reported to produce near-identical effects. The pharmacology is not known, but it is likely similar to that of LSD, which acts on serotonin, dopamine, and norepinephrinereceptors in the brain.
WARNING: Always start with lower doses due to differences between individual body weight, tolerance, metabolism, and personal sensitivity. See responsible use section.

1V-LSD is a research chemical that appears to have been first synthesized in June or July of 2021. It was announced on the same day following the announcement of the German NpSG ban of 1cP-LSD.[citation needed]
User reports indicate that the subjective effects are extremely similar to those of 1P-LSD and LSD. 1V-LSD is theorized to act as a prodrug for LSD.[1] The similarities in chemical structure it shares with LSD predict a near-identical effects profile, likely differing primarily in its rate of absorption and duration.
Very little data exists about the pharmacological properties, metabolism, and toxicity of 1V-LSD. It is presumed to have a similar toxicity and risk profile as LSD, although no evidence currently exists to support this.
1V-LSD first appeared on the online research chemical market in June or July of 2021.[2]
The provenance is not known; the substance does not appear in any academic literature pre-dating its arrival on the online research chemical market.[1]
Interestingly, the future usage of 1-akylated lysergamide derivatives as a means to bypass controlled substance laws banning LSD as a precursor was seemingly foreseen in a DEA report from 1988:
“
...a reduction in hallucinogenic activity may become acceptable to the U.S. clandestine chemist when he notes that lysergic acid amide is listed as a Schedule III substance in the CFR; therefore, structurally similar substances of this compound are exempted from the CsA amendment.
A lucid argument can then be made that lysergic acid N,N-dimethylamide is derived from lysergic acid amide rather than LSD. Carrying this theme to the next logical step one would then assume that the 1-alkyl and 1-acyl derivatives of the N,N-dimethyl isomer would also not be controlled by the CsA amendment.
”
— Donald A. Cooper, Future Synthetic Drugs of Abuse, 1988.[3]
Chemistry
Substitutive structure of a generic lysergamide molecule.
1V-LSD is a molecule of the lysergamide family. It is similar to LSD and is named for the valeryl group bound to the nitrogen of the polycyclic indole group of LSD.
The tetracyclic ergoline is characteristic of the chemical structure of ergot alkaloids. In contrast to LSD, 1V-LSD has an additional N1-valeryl group.
Chemical modifications in the N1 position are among the most frequently performed changes in the ergoline system, as the indole nitrogen is easily accessible for alkylations, acylations, Mannich reactions and Michael additions.
Based on its structural similarity to LSD, 1V-LSD likely acts as a partial agonist at the 5-HT2A receptor. The psychedelic effects are thought to primarily come from its efficacy at the 5-HT2A receptors distributed throughout the brain.
1V-LSD also likely displays binding activity at a wide range of monoamine receptors, such as those for dopamine and norepinephrine. However, there is currently no data to support these claims.
It has been theorized that 1V-LSD (as well as the acyl homologs 1P-LSD or ALD-52) are deacylated in the body to LSD by elimination of valeric acid, as shown by studies with human blood serum.[citation needed]
Subjective effects
Anecdotal reports from many users suggest that the subjective effects of 1V-LSD and LSD are virtually indistinguishable from one another. In comparison to other psychedelics such as psilocybin, LSA and ayahuasca, 1V-LSD is significantly more stimulating and fast-paced regarding the specific style of its physical and cognitive effects.
Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWikicontributors. As a result, they should be viewed with a healthy degree of skepticism.
It is also worth noting that 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. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.
Physical effects
Stimulation - 1V-LSD is usually regarded as very energetic and stimulating without being forced. For example, when taken in any environment it will usually encourage physical activities such as running, walking, climbing or dancing. In comparison, other more commonly used psychedelics such as psilocybin which are generally sedating and relaxed.
Spontaneous bodily sensations - The "body high" of 1V-LSD can be characterized as proportionally very intense in comparison to its accompanying visual and cognitive effects. It behaves as a euphoric, fast-moving, sharp and location-specific tingling sensation. For some, it is manifested spontaneously at different, unpredictable points throughout the trip, but for most, it maintains a steady presence that rises with the onset and hits its limit once the peak has been reached. At moderate to high doses of 1V-LSD, this sensation often approaches its highest level and can become so overwhelming that people may find themselves debilitated with pleasurable sensations.
Physical euphoria - It should be noted that this effect is not as reliably induceable as it is with substances like stimulants or entactogens, and can just as easily manifest as extreme physical discomfort without any apparent reason.
Tactile enhancement - Feelings of enhanced tactile sensations are consistently present at moderate levels throughout most 1V-LSD experiences. If level 8A geometry is reached, an intense sensation of suddenly becoming aware of and being able to feel every single nerve ending across a person's entire body all at once is consistently present.
Stamina enhancement - This is generally mild in comparison to the stamina enhancement produced by traditional stimulants.
Nausea - Mild nausea is occasionally reported when consumed in moderate to high dosages and either passes instantly soon after the user has vomited or gradually fades by itself as the peak sets in.
Vasoconstriction - Vasoconstriction may lead to users feeling cold, especially in the extremities.
Seizure - The likelihood is largely extrapolated from the seizures that have been reported from the use of LSD. It is thought to mainly be a risk in those who are genetically predisposed to them, particularly while accompanied by physically taxing conditions such as states of dehydration, fatigue, undernourishment or overheating.
Visual effects
Enhancements
Colour enhancement - In comparison to other psychedelics, this effect is often reported to be brighter but not as varied in its character.
Drifting(melting, breathing, morphing and flowing) - In comparison to other psychedelics, this effect can be described as highly detailed yet cartoon-like in its appearance. The distortions are slow and smooth in motion and fleeting in their appearance.
The visual geometry of 1V-LSD can be described as more similar in appearance to that of 2C-B or 2C-I than psilocin, LSA or DMT.
It can be comprehensively described through its variations as primarily intricate in complexity, algorithmic in form, unstructured in organization, brightly lit, colourful in scheme, synthetic in feel, multicoloured in scheme, flat in shading, sharp in edges, large in size, fast in speed, smooth in motion, angular in its corners, non-immersive in-depth and consistent in intensity.
In the case of higher-level geometry, this substance is level 8A dominant but is also capable of inducing 8B Geometry under the right circumstances.
Hallucinatory states
1V-LSD is capable of producing a full range of hallucinatory states in a fashion that is significantly less consistent and reproducible than that of many other commonly used psychedelics, specifically tryptamines like DMT or psilocybin mushrooms.
Machinescapes - This component is a rare effect that typically only occurs at very strong to heavy doses, and not as consistently as with notably visual psychedelics like DMT, ETH-LAD, and 2C-P, and atypical psychedelics like salvia.
While traditional psychedelics such as LSA, ayahuasca and mescaline will induce internal hallucinations near consistently at level 5 geometry and above, 1V-LSD will for most simply go straight into Level 8A visual geometry.
This lack of consistently induced hallucinatory breakthroughs means that for most, LSD is limited in depth. When they do occur, they can be described in terms of their variations as lucid in believability, interactive in style, new experiences in content, autonomous in controllability and geometry-based in appearance.
Anxiety & Paranoia - This effect is not as common at low to moderate doses and is less likely to occur when the basic rules of set and setting are taken into account. It should be noted that this inconsistently induced effect is seemingly more likely to manifest when used with cannabis. This combination should be used with extreme caution if one is not experienced with psychedelics, meaning that the user should adequately pace themselves with a fraction of their usual amount. It is commonly reported that psychedelics can to a certain extent counteract some of the perceived mental cloudiness or intoxicating effects of THC causing the user to in turn use more cannabis than is needed which can often lead to an overwhelmingly anxious headspace or a "bad trip".
Cognitive euphoria - This component is, generally speaking less consistent and pronounced than it is with substances like psilocybin and MDMA. The mental euphoria experienced on LSD is usually simply due to an enhancement of the user’s current psychological and emotional state coupled with its more regularly occurring effect, physical euphoria.
Laughter fits - This can manifest prominently during a 1V-LSD experience, particularly during the come up phase, often resulting in bouts of uncontrollable giggles and laughter that can form a feedback loop if around others who are also under the influence.
Synaesthesia - In its fullest manifestation, this is a very rare and non-reproducible effect. Increasing the dosage can increase the likelihood of this occurring, but seems to only be a prominent part of the experience among those who are already predisposed to synaesthetic states.
Alcohol - Alcohol's central depressant effects can be used to reduce some of the anxiety and tension produced by 1V-LSD. However, alcohol can cause dehydration, nausea and physical fatigue which can negatively impact the direction of the trip. Users are advised to pace themselves and drink a portion of their usual amount.
Benzodiazepines - Benzodiazepines are highly effective at reducing the intensity of 1V-LSD's effects through the general suppression of brain activity.
Cannabis - Cannabis strongly intensifies the sensory and cognitive effects of 1V-LSD. 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.
MDMA - 1V-LSD and MDMA are highly synergistic and mutually enhance each other's physical, cognitive, and visual effects. The synergy between these substances is unpredictable, and it is advised to start with markedly lower doses than one would take for each individually. There is some evidence that suggests LSD increases the neurotoxicity of MDMA, which may be relevant to 1V-LSD as well.[4][5][6]
Experience reports
Anecdotal reports which describe the effects of this compound within our experience index include:
Toxicity and harm potential
This toxicity and harm potential section is a stub.
As a result, it may contain incomplete or even dangerously wrong information! You can help by expanding upon or correcting it. Note: Always conduct independent research and use harm reduction practices if using this substance.
The toxicity and long-term health effects of recreational 1V-LSD use have not been studied. This is because 1V-LSD is a research chemical with almost no history of human use.
Anecdotal reports suggest that there are no negative health effects attributed to simply trying 1V-LSD by itself, at low to moderate doses, and using it very sparingly (although nothing can be completely guaranteed). Independent research should always be conducted to ensure that a combination of two or more substances is safe before consumption.
Based on its similarity to LSD, 1V-LSD is assumed to be physiologically well-tolerated with a extremely low toxicity relative to dose. There are relatively few physical side effects that have been reported following acute 1V-LSD exposure.
However, as with LSD and psychedelics in general, it is likely that 1V-LSD can act as a trigger for those with underlying mental disorders. Those with a personal or family history of mental illness are generally advised not to use this substance, particularly when outside of a supervised medical setting.
1V-LSD has no known toxic dose. However, higher doses increase the risk of adverse psychological reactions. These reactions include anxiety, delusions, panic attacks and, more rarely, seizures. Medical attention is usually not needed except in the case of severe psychotic episodes or the ingestion of fake acid (such as 25i-NBOMe or DOB). Administration of benzodiazepines or antipsychotics can help to relieve the acute negative cognitive effects of 1V-LSD.
Dependence and abuse potential
Although no formal studies have been conducted, it is assumed that like LSD itself, 1V-LSD is non-addictive with a low abuse potential.
There are no literature reports of successful attempts to train animals to self-administer LSD — an animal model predictive of abuse liability — indicating that it does not have the necessary pharmacology to either initiate or maintain dependence.[7]
Likewise, there is virtually no withdrawal syndrome when chronic use of LSD is stopped.[citation needed] It is assumed that 1V-LSD shares these properties with LSD.
Tolerance to the effects of 1V-LSD is built almost immediately after ingestion. After that, it takes about 5-7 days for the tolerance to be reduced to half and 14 days to be back at baseline (in the absence of further consumption). 1V-LSD produces cross-tolerance with [[Cross-tolerance::all psychedelics]], meaning that after the use of 1V-LSD they will have a reduced effect.
Dangerous interactions
Warning:Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).
Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.
The following substances are listed on the assumption that 1V-LSD possesses a similar if not the same dangerous interactions profile as LSD, and may include more due to its status as an unstudied research chemical.
[[Wikipedia:Lithium_(medication)|DangerousInteraction::Lithium]] - Lithium is commonly prescribed for the treatment of bipolar disorder. There is a large body of anecdotal evidence that suggests taking it with psychedelics significantly increases the risk of psychosis and seizures. As a result, this combination is strictly discouraged.
"[[UncertainInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Cannabis may have an unexpectedly strong and unpredictable synergy with the effects of 1V-LSD. Caution is advised with this combination as it can significantly increase the risk of adverse psychological reactions like anxiety, paranoia, panic attacks, and psychosis. Users are advised to start off with only a fraction of their normal cannabis dose and take long breaks between hits to avoid unintentional overdose.
"[[UnsafeInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Tramadol is well-documented to lower the seizure threshold[8] and psychedelics may act to trigger seizures in susceptible individuals.[citation needed]
Legal status
Internationally, 1V-LSD is not scheduled under the UN Convention on Psychotropic Substances. It is considered to exist in a legal grey area in many countries, meaning that while it is not specifically illegal, individuals may still be charged for its possession under certain circumstances such as under analogue laws and with the intent to sell or consume.
Austria: 1V-LSD is technically not illegal but it may fall under the NPSG (Neue-Psychoaktive-Substanzen-Gesetz Österreich) as an analogue of LSD, thus making it illegal to supply for human consumption.[9][10]
Czech Republic: 1V-LSD is not scheduled as a controlled substance in the Czech Republic as of June 05, 2025.[11]
Germany: 1V-LSD is controlled under the NpSG (New Psychoactive Substances Act)[12] as of October 7, 2022.[13] Production and import with the aim to place it on the market, administration to another person and trading is punishable. Possession is illegal but not penalized.[14]
Japan: 1V-LSD is a controlled substance in Japan as of March 20, 2023.[15]
Latvia: 1V-LSD is illegal in Latvia. Although it is not officially scheduled, it is controlled as an LSD structural analog due to an amendment made on June 1, 2015.[16]
Switzerland: 1V-LSD can be considered a controlled substance as a defined derivative of Lysergic Acid under Verzeichnis E point 263. It is legal when used for scientific or industrial use.[17]
Turkey: 1V-LSD is a classed as drug and is illegal to possess, produce, supply, or import.[18]
United Kingdom: 1V-LSD is illegal to produce, supply, or import under the Psychoactive Substance Act, which came into effect on May 26, 2016.[19]
United States: Since 1V-LSD can be considered a prodrug for LSD, its possession and sale may be prosecutable in the United States under the Federal Analogue Act.[20]
