1-Propionyl-d-lysergic acid diethylamide (also known as 1P-LSD) is a novel psychedelic substance of the lysergamide class. It is structurally related to LSD and other novel lysergamides like 1cP-LSD, 1B-LSD, and 1V-LSD. It is thought to produce its effects by stimulating serotonin receptors in the brain, although the precise mechanism is not known.

1P-LSD has been sold online as a research chemical (also called "designer drug") since 2015, but the original synthesis date of 1P-LSD is unknown. Unlike most research chemicals, it has no documented record in the research literature before its emergence on the online research chemical market in 2015.[1]

It was marketed as a legal alternative to LSD alongside other novel lysergamides like ALD-52, ETH-LAD, and AL-LAD.[2] In 2019, it became part of a group of molecules studied by the French laboratory Caulredaitens.[citation needed]

Subjective effects include geometric visual hallucinations, time distortion, enhanced introspection, conceptual thinking, euphoria, and ego loss. User reports indicate that the subjective effects of 1P-LSD are extremely similar to those of LSD. It is theorized to act as a prodrug for LSD.[3]

This hypothesis is supported by the results of a study that demonstrated 1P-LSD is metabolized to LSD in rats.[2] This predicts a near-identical effect profile, likely differing mainly in its rate of absorption and duration. Its classical psychedelic effects and favorable tolerability has led it to become popular among novel substance users who use it interchangeably with LSD.

Very little data exists about the pharmacological properties, metabolism, and toxicity of 1P-LSD. It is presumed to have a similar toxicity and risk profile as LSD, although there are no formal studies that prove this. It is highly advised to use harm reduction practices if using this substance.

History and culture

1P-LSD first appeared on the online research chemical market in January 2015.[1] Although it was likely discovered in an academic setting, it is unknown who first synthesized 1P-LSD, as the substance does not appear in any academic literature pre-dating its arrival on the research chemical market.[3]

Interestingly, the future usage of 1-alkylated lysergamide derivatives as a means to bypass controlled substance laws banning LSD as a precursor was foreseen in a DEA report from 1988:

Chemistry

1P-LSD is a semisynthetic compound of the lysergamide family. It is similar to LSD and is named for the propionyl group bound to the nitrogen of the polycyclic indole group of LSD. Propionyl consists of the carbonyl chain CH3CH2CO- bound to an amino group.

1P-LSD is homologous to ALD-52, which holds an acetyl group bound to the nitrogen instead of the propionyl group bound at the same location. The structure of 1P-LSD contains a polycyclic group featuring a bicyclic hexahydro indole bound to a bicyclic quinoline group. At carbon 8 of the quinoline, an N,N-diethyl carboxamide is bound.

Pharmacology

Further information: Serotonergic psychedelic

Based on its structural similarity to LSD, 1P-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.

1P-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 experimental data to support these claims.

It has been theorized that 1P-LSD may act as a prodrug for LSD. While 1P-LSD shows only 38% the potency of LSD in mice, LSD is detected via LC-MS when 1P-LSD is incubated in human serum. Follow-up studies are currently being conducted to compare the affinity and selectivity of LSD and 1P-LSD at 5-HT receptors, and to determine whether 1P-LSD is hydrolyzed to LSD in vivo.[3] Otherwise, it is possible that 1P-LSD possesses intrinsic activity.

Prior to the publishing of the above-cited research, medicinal chemist and psychedelics researcher David E. Nichols reportedly commented on the potential 1P-LSD serotonin receptor binding dynamics in private correspondence:

A 2020 study on two human male volunteers found that the levels of 1P-LSD in the serum after administration quickly diminished within the first hour while LSD has been found consistently during the experiment, which further supports the prodrug theory.[6] The study also found that LSD's bioavailability after oral ingestion of 1P-LSD was close to 100%.

Subjective effects

Anecdotal reports from many users suggest that the subjective effects of 1P-LSD are so similar to that of LSD so as to be virtually indistinguishable from one another. In comparison to other psychedelics such as psilocybin, LSA and ayahuasca, 1P-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 PsychonautWiki contributors. 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 ☠.

Combination effects

  • Alcohol - Alcohol's central depressant effects can be used to reduce some of the anxiety and tension produced by 1P-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 1P-LSD's effects through the general suppression of brain activity.
  • Cannabis - Cannabis strongly intensifies the sensory and cognitive effects of 1P-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.
  • Dissociatives - 1P-LSD enhances the cognitive, visual and general hallucinatory effects of dissociatives. Dissociative-induced holes, spaces, and voids and internal hallucinations become more vivid and intense on 1P-LSD. These effects correspond with an increased risk of confusion, delusions, and psychosis.
  • MDMA - 1P-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 1P-LSD as well.[7][8][9]
  • Psychedelics - When used in combination with other psychedelics, 1P-LSD's physical, cognitive, visual, auditory, and transpersonal effects intensify and synergize strongly. If choosing to combine psychedelics, it is recommended to start with significantly lower dosages than one would take for either substance individually
  • Stimulants - Combined with psychedelics, stimulants can cause severe *'''Anxiety, *'''Panic attacks, *'''Thought loops, and*'''Paranoia.

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 1P-LSD use have not been studied. This is because 1P-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 1P-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, 1P-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 1P-LSD exposure.

However, as with LSD and psychedelics in general, it is likely that 1P-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.

It is strongly recommended that one uses harm reduction practices when using this substance.

Overdose

1P-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 1P-LSD.

Dependence and abuse potential

Although no formal studies have been conducted, it is assumed that like LSD itself, 1P-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.[10] Likewise, there is virtually no withdrawal syndrome when chronic use of LSD is stopped.[citation needed] It is assumed that 1P-LSD shares these properties with LSD.

Tolerance to the effects of 1P-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). 1P-LSD produces cross-tolerance with all psychedelics, meaning that after the use of 1P-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 1P-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.

Legal status

1P-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: 1P-LSD is technically not illegal but it may fall in the NPSG (Neue-Psychoaktive-Substanzen-Gesetz Österreich) as an analogue of LSD, thus making it illegal to supply for human consumption.[12][13]
  • Canada: 1P-LSD is not mentioned in the Controlled Drugs and Substances Act, so it is technically not illegal.[citation needed]
  • Czech Republic: 1P-LSD is a controlled substance as of January 1, 2014.[14]
  • Denmark: As of August 25, 2015, 1P-LSD is specifically named on the list of illegal substances.[15]
  • Estonia: 1P-LSD is an ainete I (Schedule I) controlled substance as of June 1, 2017.[16]
  • Finland: 1P-LSD is a controlled substance as of November 15, 2018.[17]
  • Germany: 1P-LSD is controlled under the NpSG (New Psychoactive Substances Act)[18] as of July 18, 2019.[19] 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.[20]
  • Japan: 1P-LSD is a controlled substance.[21]
  • Latvia: 1P-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.[22]
  • Lithuania: 1P-LSD is illegal in Lithuania and is specifically named on the list of illegal substances since September 21, 2015.[23]
  • Norway: 1P-LSD is a controlled substance as of February 14, 2013.[24]
  • Romania: 1P-LSD is a controlled substance.[25]
  • Singapore: 1P-LSD is a Class A controlled substance.[26]
  • Sweden: Following its sale as a designer drug, 1P-LSD was made illegal in Sweden on January 26, 2016.[27]
  • Switzerland: 1P-LSD is a controlled substance specifically named under Verzeichnis E. It is illegal as of December 2015.[28]
  • Turkey: 1P-LSD is illegal in Turkey as of February 2016.[29]
