Key Takeaways:

  • 1cp-LSD (1-cyclohexyl-lysergic acid diethylamide) is a hallucinogenic drug similar to LSD.
  • 1cp LSD is not as potent or powerful as regular LSD, but it produces similar effects.
  • 1cp LSD can cause hallucinations, an altered sense of time and reality, and changes in mood.


You have LSD and 1p LSD; surely there can’t be more. Right? Well, you also have 1cp LSD, which is another variation of acid. This has probably left you asking what 1cp acid is and why it’s different from the other two forms that you know.

1cp LSD is the lesser-known variant, and it is an acylated derivative of acid that is commonly sold as a designer drug. 

While it is not nearly as prevalent as 1p LSD or LSD, it has been shown to have similar psychoactive effects to the former of the two.

In this guide, we will take you through everything there is to know about 1cp LSD, the way it works, and how it’s different from regular acid. With this knowledge, you should be able to make an informed choice about whether it’s right for you.


What is 1cp LSD?

1cp LSD (1-cyclopropyl-lysergic acid diethylamide) is an acylated form of lysergic acid (LSD). It was first POPULARISED in 2020 and has since been found to have similar psychoactive effects as 1p LSD and regular LSD [1].

It can be taken using three paper sheet products, or blotter paper, that is placed UNDER the tongue so that it reaches the bloodstream faster.


Pro Tip: 1cp LSD is commonly sold as a designer drug, and it has become increasingly popular with those looking for different forms of hallucinogens.


1cp LSD works in the same way that 1p LSD and regular LSD do; by binding to serotonin receptors in the brain, 1cp acid acts on the central nervous system to produce its psychoactive effects.

When 1cp LSD is taken, it increases levels of serotonin and dopamine in the brain, which results in feelings of euphoria, hallucinations, and altered perception.


Timothy Leary LSD Quote (White)


How is 1cp LSD Different Than Regular Acid?

1cp LSD is different from 1p LSD and regular acid in three primary ways:

  • It has a higher affinity for serotonin receptors than 1p LSD or regular acid, making it more potent.
  • It has a longer duration of action; 1cp LSD can last up to 10 hours, while 1p LSD usually only lasts up to 6 hours.
  • 1cp LSD has a higher bioavailability; it is more easily absorbed than 1p LSD or regular acid, resulting in a faster onset of effects.


Pro Tip: Unlike 1p LSD, 1cp is not a member of the LSD analogs. This means the analytical and behavioural characterization of the drug is different.


Benefits of 1 cp LSD

1cp LSD has become increasingly popular with those looking for a safe and effective alternative to 1p LSD or regular acid.

The HIGHER affinity for serotonin receptors makes it more potent than 1p LSD, allowing users to experience greater intensity of effects in a shorter amount of time [2].

Additionally, 1cp acid’s LONGER duration of action and higher bioavailability means that it can be taken in smaller doses for a more intense experience.


Pro Tip: Like LSD, 1cp is part of the New Psychoactive Substances Act, so care should be taken when using designer drugs like this.


1cp is one of the research chemicals that has been used in mice to study hallucinogenic substances. These studies FOUND that the effects were quite similar to 1p LSD [3].

1cp LSD also has fewer side effects than 1p LSD or regular acid, making it a safer option for those looking to EXPERIMENT with hallucinogens. However, those with a history of mental illness should still avoid it.


Does 1cp Show Up in Drug Testing?

1cp acid does NOT usually show up in drug testing; however, 1p LSD and regular acid may be detected in certain tests.

It is important to note that 1cp acid is still a NEW substance and has not been studied extensively. Therefore, it is always best to use caution when taking any designer drug.

To Conclude

1cp LSD is the less-known acid derivative and is gaining popularity as a safer alternative to 1p LSD or regular acid. 

1cp LSD has a higher affinity for serotonin receptors, making it more potent than 1p LSD, and it also has a longer duration of action and higher bioavailability.
