1P LSD first debuted online as a research chemical in 2015. It has been sold as a designer psychedelic drug ever since. Little is known about its invention as academic literature about the substance does not exist prior to its debut online. Due to the lack of analytical, chemical, and pharmacological data on 1P LSD, conclusive scientific evidence is lacking on its properties, behavior, and risks. However, it is assumed that 1P LSD functions similarly to LSD. According to user accounts, its subjective effects are almost identical.
1P LSD is considered an analogue to LSD. An analogue is a substance that is structurally and functionally similar to the original substance. It was created by modifying the molecular structure of LSD, probably in an attempt to produce a novel derivative of LSD that would technically fall into a legal loophole in many countries. 1P LSD is also a homologue of ALD-52, which means that a molecular chain was added to its parent molecule.
The United States does not control 1P LSD on the federal level. However, it could be considered an analogue, which would make it illegal under the Federal Analogue Act.
What You Will Learn About 1P LSD
- 1P LSD is a psychedelic substance of the lysergamide class and is considered an analogue of LSD and homologue of ALD-52. It also could be a “prodrug” of LSD.
- The legality of 1P LSD varies from country to country. However, it is illegal in 13 countries.
- Because it is so closely related to LSD, it is considered relatively safe to use. However, there are increased risks if you have a pre-existing medical condition, heart condition, or are on certain kinds of medications.
- 1P LSD first appeared online in 2015 as a designer drug. We don’t know who first created it, although some speculate that it was Alexander Shulgin.
What is 1P LSD?
1P LSD is short for 1-propionyl-lysergic acid diethylamide. As an analogue of LSD and homologue of ALD-52, it is classified as a psychedelic substance of the lysergamide class. 1P LSD is made by adding a propionyl group to the nitrogen molecule of LSD’s indole. In other words, it is the same substance as LSD with an additional chemical chain. Recently, it has become available as a research chemical in the form of blotters and powdered material. Typically, it takes 45-90 minutes to begin to feel the effects and lasts anywhere between 8-12 hours.
Though 1P LSD functions similarly to LSD, too little research exists to make definitive claims. However, due to its chemical similarities, it functions as a serotonergic substance. It binds to the 5-HT serotonin receptors in the brain or body. The way LSD binds to the 5-HT2A receptor, in particular, causes a cross-activation of the 5-HT2A receptor heteromer. In other words, this relationship produces long-lasting psychedelic effects. 1P-LSD probably binds with the monoamine receptors responsible for dopamine and norepinephrine but, again, little data exists to back up these claims.
A study from 2015 indicated that 1P-LSD shows 38% the potency of LSD in mice, though the drug did exhibit LSD-like behavior. There is a theory that 1P-LSD may act as a prodrug for LSD, which would mean that it turns into LSD once metabolized in the body. However, more studies need to be conducted in order to determine how 1P-LSD functions and if it is capable of producing its own psychedelic effects.
1P LSD vs LSD: What’s the Difference?
Subjectively speaking, users claim that the effects are more or less identical. However, a recent study investigated the similarities and differences in mice. Researchers found that 1P LSD shows 38% of the potency of LSD. This could indicate that 1P LSD is a prodrug, which means that it metabolizes into LSD in the body. The process could make 1P LSD weaker in comparison as well as slower to take effect. According to users, however, this does not seem to accurately reflect their experiences.
The main differences include:
- Molecular weight: LSD, 320g/mol | 1P LSD, 380g/mol.
- 1P LSD: has three more carbons and one more oxygen in its molecular structure than LSD has.
- Legalities: LSD is an illegal drug in most countries. 1P LSD is a research chemical and is legal.
- Effects: 1P LSD may be more stimulating and fast-paced in regard to its physical and cognitive effects. However, overall, the average user expresses that they cannot tell the difference.
Overall, more scientific research needs to be done in order to determine how they compare to and differ from one another.
As research is scarce, information about the effects of 1P-LSD comes from subjective experiences. Users purport that its effects are identical to LSD and the two drugs cannot be told apart. Generally, 1P-LSD is featured as an energetic, stimulating drug that feels fast-paced but not forced. The effects may vary from person to person but according to users’ accounts they include:
- A euphoric body high that is more intense compared to its visual or cognitive effects.
- Tingling sensations at specific locations on the body.
- Dilated pupils.
- An increase in stamina.
- Tactile enhancement.
- Occasional nausea when consumed in moderate or high doses.
- Appetite suppression.
- Auditory enhancement.
- Hallucinations such as color enhancement, geometry, and distortions characterized as cartoon-like in appearance.
- Feelings of unity and interconnectedness.
- Enhanced analytical/creative/conceptual thinking.
- Personal bias suppression.
- Anxiety and Paranoia (not common in low or moderate doses and unusual. unless factors like set and setting are triggering).
- Increase in focus (characteristically it feels less “forced” than other psychedelics).
- Cognitive euphoria.
- Fits of laughter (normally as it is taking effect).
- Dissolution of ego.
- Time distortion.
Benefits & Risks
Concerning the risks and benefits of 1P LSD, know how much you’re taking and what kind of experience you are looking for. If you’re new to psychedelics, doing it alone might not be advisable. An unfavorable set and setting could potentiate a series of issues.
If you’re taking medications or have a pre-existing condition, particularly those defined as cardiovascular or mental, then consult a trained physician or expert before taking any substance. There is a risk of vasoconstriction in the heart, and psychosis for bipolar disorder and schizophrenia. Furthermore, mixing certain pharmaceutical drugs may counter-interact with 1P LSD as well. Benzodiazepine tends to lower the effectiveness of lysergic acid diethylamide and any other psychedelic substance. Mixing certain antidepressants with LSD can result in serotonin syndrome due to an overload of serotonin in the central nervous system.
Other concerns include HPPD and PTSD. HPPD, or hallucinogen persisting perception disorder, is a disorder where users see “visual snow” long after the trip has ended. This can disrupt an individual’s ability to perform regular tasks due to the distraction caused by visual snow. In more extreme cases HPPD can result in severe hallucinations for prolonged periods of time.
All these factors indicate the need for preparation and forethought to reduce the risks of taking 1P LSD.
Aside from that, the risks of 1P LSD are technically unknown. Since science governs the area of medicine, when we speak about a substance we cannot make definite claims about them unless backed up by science. Personal accounts, even if there are thousands, cannot technically be credited as factual. However, 1P LSD appears to function like LSD, which would make it a relatively low-risk drug since scientific evidence on LSD shows that there are minimal adverse effects.
Top Reported Benefits
Recently, a resurged interest in LSD has led scientists to reconsider the studies that were conducted in the 50s and 60s. Those investigations primarily focused on treating depression, post-traumatic stress disorder, drug dependency, and reducing anxiety in end-of-life patients. Since the effects are similar to LSD, it might be able to address these issues and their associated symptoms.
The top reported benefits include:
- Dissolution of the ego.
- A decrease in anxiety and depression.
- Spiritual enhancement and feelings of unity.
Common Risks or Side Effects
Common risk and side effects could include:
- Increased bodily temperature.
- Appetite suppression.
- Increased blood pressure/heart-rate/perspiration.
- Visuals such as enhanced colors/geometric patterns/cartoon-like imagery.
- Time distortion.
- Increased stamina.
Is 1P LSD Legal?
1P LSD is available as a research chemical but is illegal in thirteen countries: Denmark, Finland, Germany, Estonia, Japan, Latvia, Lithuania, Norway, Sweden (listed as health hazard), and Switzerland. Romania classifies 1P LSD, but it is not technically illegal. In the United Kingdom, 1P-LSD may be illegal under the Psychoactive Substances Act. In the United States, 1P LSD is not controlled at the federal level. However, it could be considered an analogue to LSD in which case it would be illegal under the Federal Analogue Act.
How long does 1P LSD Trip last?
The trip can last anywhere between 8-12 hours.
When was 1P LSD Synthesized?
Good question. That remains unknown, but we do know that it appeared online as a designer drug in 2015.
What is the High Like on 1P LSD?
The high on 1P LSD is similar to LSD. It is a serotonergic substance, which means it’s a stimulating high that enhances feelings of euphoria and your experience of the environment. Not everyone has visuals but they tend to be a common experience.
How Long Does it Take for 1P LSD to Kick In?
It usually takes around 45-90 minutes to begin to feel the effects.
Does 1P LSD Show Up on a Drug Test?
1P LSD will only show up in an LSD drug test. LSD only shows up a maximum of 48 hours after ingestion in urine, not in hair.
Do You Have Real 1P LSD?
It is always a good idea to test your substances! If you use an Ehrlich’s reagent test, it’ll turn purple. On a marquis reagent test, it varies. Some results say dark green. Erowid would indicate that it’s real with the response: “no reaction.”
Does 1P LSD have a Comedown?
The comedown is between 2-4 hours with after effects lasting about two hours. However, the comedown can last up to 24 hours.
