Taking LSD is great, and you might end up having a fantastic trip that feels more like a soul-searching adventure than your run-of-the-mill high. But how do you take LSD, and what are the LSD blotters you’ve probably heard about?

A sheet of acid, a tab of acid, acid tabs, or an LSD paper sheet – there are many names for it. Most of the time, LSD is taken via blotter paper that is placed under the tongue. 

This helps the drug work faster, making it a pretty convenient way of getting high.

This guide will take you through everything you need to know about LSD papers, blotters, and how they work. Additionally, it will give you a good idea of the other names they are known by so that you’re prepared when you go to buy them.


What are LSD Blotter Papers?

LSD blotter papers are thin, absorbent paper squares that have been soaked in liquid LSD, and they DISSOLVE like sugar cubes. They’re usually DECORATED with spectacular designs that make them look like art prints.

Commonly called acid, the blotters can come in strips of SEVERAL small tabs or a single large sheet. In either case, the paper is PERFORATED into individual dose-sized squares [3].

LSD is absorbed into the blotter paper, and when placed under your tongue, it quickly enters your bloodstream. 

The active dose of LSD in a single tab is usually between 100 and 250 micrograms, so a SINGLE sheet can be divided into several doses.


Pro Tip: It can take anywhere from a few minutes to half an hour for the effects of the LSD to kick in, and they usually last 8 – 12 hours.

What Do Acid Sheet Effects Feel Like?

The effects of an LSD paper sheet are hard to explain because they can be so different from one person to another. This synthetic drug tends to INTERACT with the serotonin receptors, producing various effects.


Pro Tip: Illicit drugs like LSD should be used with caution and never mixed with other drugs as this is an extremely dangerous practice that can have severe and negative effects.  


The most common effects INCLUDE visual hallucinations, synesthesia (when senses mix up), and ALTERED states of consciousness. 

People often experience relaxation and euphoria, increased energy levels, heightened creativity, and ENHANCED sensory perception [1].

It is important to note that LSD tabs can cause serious side effects, especially when you use the drug repeatedly, so you should ALWAYS be careful and take the drug in a safe environment.

Some of these side effects include:

  • Nausea
  • Anxiety and paranoia
  • Feeling like you’re losing control
  • Psychosis
  • Depression


Pro Tip: It’s always best to start with a low dose and work your way up until you find the right dosage for yourself and use it responsibly to avoid substance abuse.

Those who suffer from mental health conditions like schizophrenia should AVOID taking acid as they are at a HIGHER risk of developing HPPD (hallucinogen-persisting perception disorder) and drug-induced psychosis [2].


How to Take LSD Blotter Sheets?

The best way to take LSD is via acid blotter paper, as this ensures that the drug gets absorbed into your bloodstream quickly. 

To take an LSD sheet, place it under your tongue and hold it there for about 30 minutes to an hour until it dissolves COMPLETELY.

It is always a good idea to have someone nearby who can HELP you if something goes wrong and to ensure that you are in an environment that is free of distractions.

If you have a BAD trip, it is important to note that it cannot be stopped, but you can make things easier on yourself. 

Try to practice mindfulness and call a sober person you TRUST for help. You should also ensure you DON’T engage in further drug use until the high is completely finished.


Pro Tip: LSD does not cause physical dependence. However, LSD produces tolerance which can lead to drug abuse and psychological dependence.
