You’ve probably heard of LSD. You might even have tried it, but it’s not the only drug of its name on the market. You also have 1p LSD, and while this is still a form of acid, some aspects make it different.

1p LSD is a form of LSD analogue, and it has been popular as a designer drug since 2015. It remains a powerful hallucinogenic, but the full effects of 1p are still fairly unknown. Generally, it is thought to have similar effects to acid.

In this guide, we take you through everything we know about 1p LSD, the way it works, and how it compares to the standard LSD you usually find on the market.


What is LSD (Acid)?

LSD, or lysergic acid diethylamide, is a powerful hallucinogenic drug that was first created in the 1930s. 

It became part of the counterculture of the 1960s, and although it has since been ILLEGAL for recreational use in Canada, it remains popular today.

When taken orally, LSD works by ACTIVATING the serotonin receptors in the brain, which results in psychedelic experiences.

It can cause a RANGE of physical and psychological effects, including an altered perception of time and space, intense visual imagery, feelings of euphoria or terror, and changes in mood.


Pro Tip: While LSD is not addictive, the ability to build up a tolerance leaves it open for abuse. Those who struggle with drug and alcohol abuse should never take it.

What are the Risks and Side Effects of LSD?

Using LSD is NOT dangerous, but you do run the risk of a bad trip. It can cause intense panic attacks and psychosis, as well as a range of PHYSICAL effects such as nausea, dizziness, increased heart rate and blood pressure, and sweating.

Long-term use can also lead to an increased TOLERANCE for the drug, meaning users will need more of the drug to achieve the same effects.

Those with mental health conditions might also experience a higher risk of HPPD (Hallucinogen Persisting Perception Disorder), which can cause persistent visual disturbances and flashbacks.


What is 1p LSD?

1p LSD, also known as 1-propionyl-lysergic acid diethylamide, is a synthetic analogue of LSD. It was initially created in 2015 and has since become popular for its use as a DESIGNER drug in Canada and worldwide [2].


Pro Tip: 1p is considered one of several new psychoactive substances. The subjective effects mean it is not recommended for human consumption as very little is known about it compared to LSD.


1p LSD works similarly to traditional LSD, but it has an ADDITIONAL propionyl group added to the lysergic acid molecule. This makes 1p LSD more stable and longer-lasting than regular acid, as well as more potent.

It is important to note that 1p LSD is not approved for medical use and can be dangerous if taken in large doses or without proper guidance.


What About a Microdose of 1p LSD?

Microdosing 1p LSD means taking a very small amount of the drug. This can result in subtle changes in mood or cognition but without the STRONG and overwhelming effects of a full dose.

This has become popular among those looking to EXPERIENCE the benefits of 1p LSD without risking their mental or physical health.

A 1p LSD microdose is considered to be 1/20th of a standard dose, and this is thought to help improve creativity and focus while AVOIDING any psychedelic effects [3].


What are the Risks and Side Effects of 1p LSD?

1p LSD can have both positive AND negative effects on users. On the one hand, 1p LSD produces intense psychedelic experiences with spiritual and mystical elements.

On the other hand, 1p LSD can also cause anxiety, confusion, paranoia, and other unpleasant side effects when taken in high doses or WITHOUT proper guidance. 

1p LSD can also be addictive and may lead to physical dependence if taken in large doses or over a long period of time.


Pro Tip: LSD and 1p are both part of the Psychoactive Substances Act. They are considered a controlled substance and part of the psychoactive substances prohibited in the USA and Canada.


Does 1p LSD Show Up on Drug Tests?

Yes, 1p LSD can show up in drug testing, as it is a form of lysergic acid. 1p LSD is known to stay in the system for up to four days after use, so it may be DETECTABLE on urine or blood tests during this time.

It is important to note that 1p LSD has NOT been tested for accuracy on drug tests, so false positives are possible.


Pro Tip: It used to be hard to trace 1p in drug tests, but the new synthetic drugs database has a much clearer record of new substances.


What is the Difference Between 1p LSD and Regular LSD?

The main difference between 1p LSD and regular acid is the additional propionyl group [1]. This makes 1p more potent and longer-lasting than standard LSD, with the effects lasting up to 10 hours or more.

Regular LSD usually only lasts for about 6-8 hours, which can make 1p a better option for those who want to extend their psychedelic experience.

While both forms of acid can be taken through oral AND intravenous administration, oral 1p tends to take longer to take effect and lasts for a shorter period of time when taken orally.

In addition, 1p LSD is more RESISTANT to environmental degradation than traditional acid, so it can be stored for longer periods of time without losing its potency.

Unlike LSD, 1p can be mixed with other drugs, such as alcohol, which can cause a depressant effect and lower the intensity of 1p LSD if needed. 

The same goes for benzodiazepines which can have a very similar effect to alcohol when mixed with 1p LSD.


Best Place to Buy LSD Online in Canada

If you want to buy 1p LSD, Canada, you might struggle to find a reputable dealer. As a designer drug, you do need to be careful, as dealers have been known to ADD chemicals and ingredients in order to cut costs. 

This can be potentially harmful, so always go with a trusted supplier.

That way, you know what you’re getting with every purchase, and you don’t run the risk of laced drugs.


To Conclude

1p LSD is a powerful and longer-lasting form of acid, but it’s important to remember that 1p LSD is not approved for medical use in Canada

Always be sure to get your 1p from a trusted supplier, as there are many ROGUE dealers out there who may try to pass off an impure product.

By understanding 1p LSD and the risks involved, you can make an educated decision about whether or not 1p is right for you. As always, it’s important to REMEMBER that 1p LSD should be used responsibly.
