Key Takeaways:

  • LSD works by binding to specific receptors in the brain and amplifying sensory perceptions.
  • Effects of LSD can vary significantly from person to person but can include hallucinations, altered perception of time and space, changes in mood, and increased heart rate.
  • Users must be aware of the risks associated with taking LSD and take necessary precautions.


Are you wondering what LSD is, how it works, and what could potentially happen to you if you take it? Well, no need to worry – we have all the answers right here!

LSD is a psychedelic drug that can alter a person’s emotions, thoughts, and perceptions. It usually works like a stimulant that will interact with your brain to give you a more intense experience.

Whether you’re a novice or an experienced user looking for more information, read on for an in-depth look at everything related to LSD (including notes along the way).


Knowing What An Acid Is

Acid is the popular lysergic acid diethylamide (LSD), a psychedelic drug that can produce mind-altering effects. 

It usually comes in the form of tiny pieces of paper or tablets with designs on them, and they are often referred to as “TABS or Sugar Cubes.”

It’s important to be able to differentiate between LSD and other drugs. As it is a hallucinogenic drug, it’s not easy to spot the DIFFERENCE between it and other drugs’ negative effects.


Here are some tips to help you determine if what you’re looking at is acid:


Its colour is usually light yellow or transparent, translucent. It is sometimes found in different colours, but this may result from impurities from other substances added to the drug when it is being manufactured.

The tabs can vary from white to orange or even brown, depending on how they were produced and stored. They will generally have a yellowish hue, but it’s best to be sure BEFORE ingesting anything.



The texture is usually sticky, and the tabs can be quite thick. They will also have perforations on them that make it easy to tear them apart into smaller pieces.

The tabs themselves may be a bit rigid, but it’s not uncommon for them to be quite pliable. It is important to note that the texture and consistency of the drug can VARY from batch to batch depending on how it was produced.



Although it is not always easy to detect, you may be able to smell a slight metallic odour when the drug is in its pure form. Again, this can VARY depending on what other substances were added during manufacture and storage.



The main active ingredient in LSD is usually d-lysergic acid diethylamide or D-LSD for short. Although it can vary from batch to batch, sugar, glucose and starch are other commonly found ingredients.


Pro Tip: Use a black light to check for “blotter” paper; if it glows a fluorescent blue colour, you can be sure that the drug is present.



The Science Of LSD

The science behind acid can often seem complicated and overwhelming. It is a powerful, semi-synthetic drug that has been around for over 50 years and continues to be used recreationally. 

It’s known for its intense hallucinogenic effects, but what does LSD do to you?

The answer lies in the way it INTERACTS with the brain. When taken, the ingredient interacts with the serotonin receptors in your brain to produce various effects. This binding trigger changes in neural pathways that have different levels of emotions, thoughts and perceptions.

However, one must note that the entire process of how it works is quite complex and multi-faceted. Various different compounds can interact with the brain, making it difficult to predict how a particular user may experience its effects.


Physical Effects of LSD

What does LSD do to your body? The physical effects of acid are wide-ranging and can vary from person to person. However, some of the most common effects can be the same for most users.


Here is what acid does when it comes to the physical effects:

Increased Heart Rate And Blood Pressure

When under the influence, the user will typically experience an increased heart rate and a rise in blood pressure.

This can lead to feelings such as uneasiness, and these effects are usually temporary. Still, it is important to note that if these symptoms become unmanageable, it is best to seek help from a medical professional.

Additionally, those with existing heart CONDITIONS should be very careful when using this and consult a doctor before taking any form of the drug.



Nausea is a common side effect of taking acid. This can range from mild uneasiness to more severe vomiting and dizziness.

It is important to note that the intensity of these feelings can depend on the person’s TOLERANCE, as well as the potency and purity of the drug. 

Furthermore, nausea may accompany other unpleasant effects such as headache, sweating and stomach cramps.


Dilated Pupils

When the drug is taken, pupils tend to dilate, which can cause SENSITIVITY to light. This can make it difficult for someone under the influence of acid to navigate in an environment with bright lights.



It is common for users to experience increased levels of sweating when under the influence of acid. This can range from mild perspiration to intense sweat, leaving a user feeling very UNCOMFORTABLE.

If you experience this side effect, we recommend finding a cool and comfortable place to rest until the effects subside.


Muscle Tension

LSD affects increased muscle tension, leading to aches and pains. It is important to note that these effects are usually TEMPORARY, but it is still best to be aware of them as they can become quite unpleasant if left unchecked.


Loss Of Appetite

Due to the drug’s psychoactive effects, users may find themselves with a loss of appetite. 

It is important to note that this effect, in particular, can be quite dangerous if left unchecked, as it can lead to MALNUTRITION and other health issues.


Loss Of Coordination

The drug can also cause a loss of coordination, making it DIFFICULT to navigate unfamiliar environments or even perform simple tasks. 

This effect tends to pass as the effects of the acid wear off, but it is important to be aware of this potential side effect.



The most common side effect associated with acid is the ability to experience visual hallucinations. While under the influence, users may see or hear things that are not real [1].

These types of hallucinations can range from mild distortions of reality to intense visions and sounds that can be very disorienting. It is important to be aware of this side effect, as it can be quite UNSETTLING.

It is also important to note that these hallucinations often result from a user’s mindset, so it is best to be aware of one’s mental state while under the influence.


Pro Tip: Ensure that you are in a safe, comfortable and familiar environment to reduce the chances of experiencing any adverse effects from LSD.


Mental Health Problems

Finally, it is important to note that acid can cause long-term mental health issues in some LSD users. These issues may include depression, anxiety, paranoia and even psychosis.


What Happens When Your Brain Is On LSD

When your brain is on LSD, it undergoes changes that can lead to POWERFUL experiences. 

The effects of the drug on your mind and body can vary significantly from person to person, but in general, it can cause several changes in your mentality and behaviour.

When a person takes acid, their brain chemistry is ALTERED, and the drug acts on various chemicals in the brain, such as serotonin, dopamine, and glutamate. 

This can lead to euphoria, changes in perception (usually results in a bad trip), and a heightened sense of creativity.

In addition, LSD users may experience intense visuals or sensory experiences. The effects created by LSD drug use are highly unpredictable and can vary from person to person.

In some cases, people may experience a feeling of UNITY with the environment or an altered sense of time.

In others, it may cause anxiety and confusion. Generally, these effects last a few hours before fading away. It is important to note that LSD is considered one of the most POTENT psychedelic drugs, and drug abuse should be used cautiously.


Pro Tip: Be sure to stay hydrated and take breaks while under the influence of acid.


The Advantages Of LSD

Even though acid is a powerful psychedelic drug, it has been found to have several potential benefits. 

While it is not without risks, research has suggested that illicit drugs can provide numerous advantages when used safely and responsibly.


Here are some of the potential benefits of LSD that researchers have identified:

  • Can reduce anxiety and depression [2]
  • Can improve creativity, focus and productivity
  • Increases empathy and compassion towards others
  • Enhances sensory perception
  • Reduces obsessive-compulsive tendencies
