Key Takeaways:

  • 1p LSD is a designer drug that is related to the psychedelic substance 1P-LSD.
  • 1P-LSD is illegal in Canada and other countries, although it’s still legal in certain states in the US.
  • 1p LSD produces similar effects as lysergic acid diethylamide (LSD), including altered thought processes, enhanced visual perception, and changes in mood.
  • The long-term side effects of 1p LSD are unknown but may include anxiety, confusion, paranoia and depression.


Wait, isn’t it just plain LSD? While LSD has been a mainstream psychedelic drug for quite some time, it’s not the only form on the market. 

Those who are a little savvier might have heard of 1p LSD, but this isn’t the case for everyone. So, what is it?

1p LSD is an analog of LSD. 1p is often used as a substitute due to its similar effects and chemical structure. 

The full effects of 1p are unknown as there have not been enough clinical studies to determine how different it is from standard acid.

In this article, we will take you through everything we know about 1p LSD and the way it works. That way, you’ll have a clearer idea of what to expect if you ever decide to try it.


What is 1p LSD?

1-propionyl-lysergic acid diethylamide (1P-LSD) is a semi-synthetic psychedelic substance of the lysergamide class. 1P-LSD is thought to produce its psychedelic effects by ACTING on serotonin receptors in the brain [1].

1P-LSD belongs to a group of related compounds known as lysergamides, which includes other well-known psychedelics like LSD and 1A-LSD. It can be taken as a human serum with intravenous or oral ingestion.

It is considered one of several NEW psychoactive substances since its creation in 2015. While it is not listed as one of the psychoactive substances prohibited by LAW in Canada, caution should still be taken.

How is 1p LSD Different Than Regular Acid?

1P-LSD is similar to LSD, with the main difference being that 1P-LSD has a propionyl group bound to the 1 position of its indole ring.

This modification appears to slightly increase 1P-LSD’s affinity for serotonin receptors in comparison to REGULAR acid and may account for some subtle differences in the subjective effects.

1P-LSD is also thought to be slightly more potent than LSD, with less of it needing to be taken in order to experience its full range of effects.


Is 1p LSD Addictive?

No, 1p LSD is not thought to be addictive as it does not activate the brain’s reward system in the same way as some OTHER psychoactive drugs do.

However, 1p-LSD can still produce compulsive and REPETITIVE use patterns that may indicate a psychological addiction.

Those who are prone to drug and alcohol abuse should not try 1p or standard acid as it could lead to DANGEROUS habits and the mixing of drugs.


Pro Tip: LSD is found under the Psychoactive Substances Act and remains a controlled substance. While 1p might be legal, it is still listed on the new synthetic drugs database, and there are restrictions.


Does 1p LSD Show up in Drug Testing?

No, 1p LSD does not show up in standard drug testing as it is not specifically tested for. However, 1P-LSD can be detected using more ADVANCED methods such as liquid chromatography-mass spectrometry (LC-MS).


Benefits of 1p LSD

One of the main benefits of 1P-LSD is its availability. 1P-LSD is much easier to acquire than regular acid, as it can be purchased legally in some countries, including Canada.

1P-LSD also has a lower rate of tolerance build-up than regular acid, which means that users don’t need to take increasingly larger doses to feel the SAME effects [2]. This makes 1P-LSD an ideal candidate for microdosing, as users don’t need to worry about needing higher doses later on.

Finally, 1P-LSD has a more subtle set of effects than regular acid, which may make it more suitable for some users who DON’T want to be overwhelmed by intense visuals and emotions.


What is 1p LSD Microdosing?

A 1p LSD microdose is a very small amount of 1P-LSD taken with the intention of producing subtle changes in mood, cognition, and perception [3].

Microdosing 1P-LSD is not intended to produce psychedelic effects but rather a subtle shift that can enhance creativity, productivity, and mental clarity.


Pro Tip: 1p LSD microdoses are typically taken 1-3 times a week, with users reporting that the effects can last for 1-2 days after each dose.
