Have you ever wondered how long LSD lasts? If so, you’re not alone – it is a question that often plagues those who are curious about the power of this powerful hallucinogenic drug.

Acid typically remains in the body for 8-14 hours, and its effects can be felt up to 12 hours after ingestion. The experience’s duration depends on various factors, such as the user’s body weight and how much LSD was consumed.

Let’s explore more on what we know about the duration of your typical LSD trip!


Overview Of LSD

LSD (Lysergic acid diethylamide), more commonly known as acid, is a POWERFUL hallucinogenic drug. It was first synthesized in 1938 by Swiss chemist Albert Hoffman and has been used recreationally and in psychotherapeutic settings [1].

When ingested, LSD causes profound alterations in conscious PERCEPTION and can produce intense and profound changes in mood, thought, and behavior.

It is known to be highly UNPREDICTABLE in terms of how long its effects will last, so it’s important to use caution when experimenting with this powerful drug.

What Does LSD Feel Like?

Lysergic acid diethylamide LSD produces intense, often unpredictable changes in MOOD and thought patterns that can last many hours. Depending on your set and setting, the acid effects can be both pleasurable and disturbing.


Here are some of the descriptions of what an acid trip feels like:

Feelings Of Spiritual Enlightenment Or Insight

One of the most common effects of acid is a feeling of SPIRITUAL enlightenment or insight. Many users report being able to have profound insights into their own lives, as well as a greater understanding of the world around them.

This feeling can be accompanied by intense emotions, such as joy and euphoria, but also fear and anxiety in some cases.

Inability To Focus On Tasks

LSD can also cause difficulty with focusing on tasks. This can be especially PROBLEMATIC when attempting to complete complex mental tasks like driving or operating heavy machinery.

Visual And Auditory Hallucinations

Some people also experience visual and auditory hallucinations while on acid. These can range from seeing geometric shapes or colors to hearing voices. It is IMPORTANT to note that these hallucinations are not real, even though they may feel incredibly lifelike and vivid.


Synesthesia is a RARE condition in which certain stimuli can cross the sensory pathways and create unusual combinations of sensations [2]. For example, someone with synesthesia might experience color when they hear a sound or taste something when they see a shape.

This phenomenon is more common in people who have taken acid, as the drug can temporarily ALTER neural pathways and cause synesthesia-like effects. 

It is important to note that these effects are not permanent and can disappear once the drug has been metabolized out of the body.

Heightened Senses

Another common effect of the drug is an INCREASED sensitivity to the senses. This can lead to a heightened appreciation for music, art, and other forms of creative expression.

It can also cause users to be more SENSITIVE to physical touch, taste, smell, or sight. Some people find these effects pleasurable, while others find them overwhelming or uncomfortable.

Intensified Emotions

LSD can also INTENSIFY existing emotions. Those who are feeling depressed may find that their depression is intensified, while those who are feeling happy and joyous may find that these feelings are amplified.

It is important to be mindful of your EMOTIONAL state before taking LSD in order to ensure a safe and enjoyable experience. Drug abuse can be dangerous and have serious negative consequences, so it is important to use caution when experimenting with any drug.

Feelings Of Interconnectedness

LSD can also cause people to feel a sense of interconnectedness or UNITY with the world around them. This feeling is often referred to as “ego death” because it can lead to feelings of insignificance and being part of something much larger than oneself.

Time And Space Distortions

Finally, LSD can cause time and space to become DISTORTED. Things may seem to move in slow motion or faster than normal, and objects can appear larger or smaller than they actually are.

Depending on your mindset and environment, these effects can be both disorienting and enjoyable.


Pro Tip: Try always to have a sober friend nearby to help you stay grounded if things start to feel too intense.


How Long Will It Take To Feel the Effects of LSD

Taking LSD can be a truly UNIQUE and transformative experience, with effects that range from spiritual enlightenment to intense auditory and visual hallucinations. But how long does it take for the drug to start working?

On average, it takes about 30 to 60 minutes for the LSD effects to kick in. Additionally, several factors can affect the waiting time for LSD, such as:

The Potency Of The Drug

The potency of the drug can also INFLUENCE how quickly it takes effect. LSD is usually found in liquid form, and concentrations can range from 10mcg/ml to more than 200mcg/ml, so be sure to check the label before taking it.

The Method Of Delivery

The method of delivery can also influence how quickly the drug takes effect. Taking acid ORALLY will usually take longer to show its effects than taking it sublingually or nasally.

Liquid LSD can also be injected directly into the bloodstream, which can cause its effects to take hold within minutes.

The User’s Metabolism

Furthermore, the user’s metabolism can influence how quickly the LSD takes effect. Those with FASTER metabolisms may find that the effects come on quicker, while those with slower metabolisms may need to wait longer before feeling anything.

The User’s Body Chemistry

Also, the user’s body chemistry can affect how long it takes for the drug to take effect. For example, those with lower levels of SEROTONIN may find that LSD affects them more quickly than others since serotonin is involved in regulating mood and behavior.


Pro Tip: Start with a small dose and gradually increase as needed to find the right balance and avoid a bad trip.


The Duration Of An Acid Trip

The duration of an acid trip can vary a lot depending on how much has been taken. Generally, it can last up to 12 hours, although the effects gradually DECREASE after the peak effects at the 6-hour mark.

However, some users report that they are still feeling lingering effects even 24 hours later. Additionally, certain factors such as metabolism and body chemistry can also affect the LENGTH of an acid trip.

It is important to remember that substance abuse can have intense effects; therefore, taking breaks during trips to AVOID unpleasant experiences is best. Also, don’t forget to drink plenty of water, as dehydration can cause negative experiences.


Factors That Affect The Duration Of An Acid Trip

LSD is a POWERFUL psychedelic drug that can cause dramatic shifts in consciousness, leading to intense spiritual and physical effects. While some of these effects fade relatively quickly, other factors can significantly impact the duration of an acid trip.

These factors include the amount taken, the user’s metabolism and body chemistry, and the method of delivery. Additionally, having a clear INTENTION when taking LSD can also influence how long its effects last.

Additionally, acid can cause psychological and EMOTIONAL effects such as euphoria, bliss, and awe that may linger even after the physical effects have worn off, leading to poor mental health.

Also, taking other drugs, such as alcohol, can PROLONG the duration of an acid trip, so it is important to be mindful of what substances are being taken and how they interact with one another.


Pro Tip: Try using mindfulness techniques to stay grounded during an acid trip, and remember that you are in control of your experience.


What Drug Tests Can Detect LSD Use?

While its effects are usually short-lived, LSD can be detected in the body for up to two months after use.

Urine, blood, saliva, and hair follicle TESTS are all used to detect LSD use. Urine tests are the most commonly used drug tests, as they can detect LSD for up to five days after ingestion.

Blood tests are more reliable and ACCURATE than urine tests, but they usually require a sample of blood drawn from the user’s arm or finger. These tests can detect LSD use for up to three days after ingestion.
