Acid is also known as lysergic acid diethylamide (LSD). Doctors used it in psychotherapy and to increase the effects of antipsychotics in the 1950s. People began to experiment with LSD as a recreational drug in the late 1960s. How long does LSD stay in your system?

LSD is also known by street names such as blotter, dots, and yellow sunshine. It is a dangerous illicit narcotic and one of the most potent mood-altering chemicals.

In this post, we will discuss how long LSD remains in the body and how long tests may detect it after a person has taken a dosage. We also go through the consequences and hazards.

How long does acid stay in your system?

When a person consumes LSD orally, it is absorbed by the gastrointestinal system and channeled into the circulation. Once in circulation, the medication goes to the brain and other organs such as the liver. LSD is broken down by the liver into several compounds. how long does lsd stay in your system

When it comes to identifying LSD in human tissue samples, researchers face several obstacles. Because people only consume small amounts, detection systems must be extremely sensitive.

LSD is also unstable, and the liver degrades it quickly. Because the period that LSD is detectable in tissues is limited, clinicians must test the samples rapidly.

Some scientistsTrusted Source has sought to provide detection tools for LSD byproducts. The levels of these chemicals that remain in the tissues, however, are still significant.

How long does lsd stay in your Urine?

When LSD is taken orally, the liver converts it into inactive chemicals. A person excretes just around 1% of LSD unaltered in urine after 24 hours.

Researchers can identify LSD in urine samples using a variety of techniques, but these procedures are not widely available. The majority of standard urine drug tests will not identify LSD.

Liquid-liquid extraction and ultra-high-performance liquid chromatography-tandem mass spectroscopy (UHPLC-MS/MS) are two procedures that researchers can utilize to detect LSD in urine.

According to studies, several inactive metabolites of LSD are detected in urine at amounts 16-43 times greater than LSD. However, researchers are unsure how these findings may aid in the detection of LSD usage.

How long does lsd stay in your Blood?

Doctors can also identify LSD in blood samples using liquid-liquid extraction and UHPLC-MS/MS.

Researchers obtained 13 blood samples within 24 hours of delivering LSD in a recent studyTrusted Source. They held the samples at below-freezing temperatures for 12 months before analyzing them.

LSD was detected in samples collected up to 16 hours following delivery in all volunteers who had received 200 micrograms (mcg) of LSD.

The researchers were able to identify LSD in samples obtained up to 8 hours after delivery in people who had received 100 mcg of the substance.

In both groups, the quantity of detectable LSD in the samples dropped with time. After 16 hours, the researchers could only identify the drug in 9 of 24 samples from the group that had received 100 mcg of LSD.

These detection technologies are very sensitive and specialized, and clinicians may not have easy access to them.

How long does lsd stay in your Hair?

Hair samples can be used to detect medications that a person used many years ago. When blood or urine samples are unavailable, they are also valuable.

Researchers can determine the time and length of consumption based on the medication by assessing the growth rate of the hair and the position of the drug’s evidence on the hair shaft.

Three reported examples of LSD residues in human hair samples were studied in a 2015 study. The concentration of LSD in the samples ranged from 1 to 17 picograms per milligram.

However, the researchers conducted their studies on LSD-treated hair rather than hair samples from persons who had used the drug.

One significant issue that researchers have when utilizing hair samples to identify LSD is that the drug is active at extremely low concentrations. If a person needs to consume a greater amount to experience any effect, the drug may be more easily detected.

There is virtually little information about LSD in hair samples. Researchers aren’t even sure if the medication is stable or detectable in these samples. how long does lsd stay in your system?

A negative result from a hair sample does not rule out the possibility that the person has used LSD. However, pubic hair samples might have been contaminated with LSD through urine.

Tissue samples from mice given intravenous doses of LSD were examined by researchers. LSD was discovered in the brain, liver, kidneys, adrenal glands, thymus, lungs, and salivary glands.

LSD in people may potentially be detectable through autopsy reports. Three autopsy reports including LSD were published in the journal Forensic Science InternationalTrusted Source.

This was the first study of LSD and its inactive constituents in human brain tissue, according to the researchers. Although they discovered LSD in brain tissue samples, it was not the cause of death in any of the instances.

Factors that influence LSD detection

Many factors can determine how long LSD is detectable, including a person’s overall health, age, and the amount of the drug used. After 72 hours, current techniques are unable to identify LSD in the urine.

The sample’s time is one of the most critical elements. LSD exits the bloodstream after around 24 hours.

After 72 hours, current assays are unable to identify LSD or its metabolites in urine samples.

Furthermore, other substances with similar chemical structures may interfere with LSD detection, depending on the test – some are more accurate than others.

Some tests, for example, have a high false-positive rate, which means they detect LSD when it is not there.

Is there any way I can get it out of my system more quickly?

Acid is swiftly cleared from your system, but there are things you can do to speed up the process.

Try out the following:

  • Hydrate. Your urine excretes the acid and its metabolites. Staying hydrated before, during, and after taking acid will help it leave your system more quickly.
  • Stop using the acid. When it comes to testing for LSD, timing is everything, and the sooner you stop taking it before a drug test, the less likely it will be detectable.
  • Exercise. Although it is not the quickest solution, exercising can enhance your metabolism. The combination of aerobic activity and weight lifting has the greatest influence on metabolism.

How long do the effects last?

Most people will feel a mild LSD reaction with a dosage of 1-3 mcg per kilogram of body weight.

People should expect to experience the effects of the medicine 30-60 minutes after taking it. Depending on the dosage, the effects may last 8-12 hours or longer.

People on LSD may have changed their awareness of their surroundings, including objects, situations, thoughts, and feelings.

After taking the same dosage of the medication, one individual may have an entirely different experience than another.

When consuming LSD, some people have flashbacks. Stress, exhaustion, and the use of other medicines at the same time can all increase the likelihood of these flashbacks. A person who has previously used LSD may also have a flashback of a trip.

LSD can also have the following side effects:

  • increased heart rate
  • increased blood pressure
  • increased breathing rate
  • rise or decrease in body temperature
  • sleeplessness
  • loss of appetite
  • shaking
  • sweating

Researchers estimated that 1.4 million persons aged 12 and up in the United States were presently taking hallucinogens, including LSD, in the 2016 National Survey on Drug Use and Health.

LSD and ecstasy were the most often used hallucinogens in 2015 and 2016. LSD is often used orally as a film (windowpane), blotter paper (microdots), sugar cubes, pill, or capsule. Reliable Source. how long does lsd stay in your system

A note about safety

Are you thinking of trying acid? Before you take the plunge, there are a few important things to consider.
If you’re going to try LSD, there are a few things you can do to make it less risky:

  • Don’t try to accomplish it alone. Make sure you have at least one sober person on hand who can step in if things get out of hand.
  • Take note of your surroundings. Ascertain that you are in a secure and comfortable environment.
  • Don’t combine medications. Never mix LSD with alcohol or other drugs.
  • Slow down. Begin with a modest dose and wait for the effects to take effect before increasing the dose.
  • Choose the best moment.LSD’s effects may be rather powerful. As a result, it’s ideal to utilize it while you’re already in a good mood.
  • Know when to forego it. If you have a prior mental health problem, such as schizophrenia, or if you take any drugs that may interact with LSD, avoid it or use extreme caution.

It is inadvisable to use LSD when pregnant.

Some patients have lasting mental symptoms, such as psychosis, but this is uncommon. Even at large dosages, LSD and other hallucinogens have negligible toxicity to organs, including the brain.

There have been no clinical investigations of flashbacks, thus doctors are uncertain if they are caused only by LSD.

The most serious risk of using LSD is the risky conduct that might emerge from the drug’s effects. When a person’s vision of the world changes, they may pay less attention to their own or others’ safety.

Other potential hazardsTrusted Source may make LSD usage unwise, such as:

  • cardiovascular disease
  • pregnancy
  • epilepsy
  • paranoid personality disorder
  • psychosis
  • organic-toxic disorder


People do not normally use LSD on a regular basis due to its profound psychological effects Source. A habitual user of LSD gel tabs will rapidly build a tolerance and require greater dosages to have any effects.

A person’s emotional, mental, and physical states normally return to normal a few days after using LSD. People seldom experience cravings for LSD after quitting, thus there are no withdrawal symptoms.


LSD is a potent, mood-altering substance that is also used as a street drug. Because of the significant psychological consequences of LSD, most people do not use it every day.

Doctors can identify LSD and its metabolites in urine samples up to 72 hours after a person has taken the drug using certain procedures.

Some tests can identify LSD in blood samples within 24 hours after consuming it. Hair samples are not as trustworthy as urine or blood samples.
examples of treatment options.
There are no FDA-approved medications for treating LSD usage. Your doctor may, however, prescribe drugs to assist in treating the symptoms of other mental diseases such as sadness and anxiety.


  1. <strong>What is the detection window for LSD in drug tests?</strong>

    LSD is not typically included in standard drug tests, so it’s not easily detectable. Most drug tests focus on substances like cannabis, opiates, and amphetamines. LSD is metabolized and eliminated from your system relatively quickly, usually within 1-3 days

  2. <strong>Can a hair follicle test detect LSD use?</strong>

    LSD is unlikely to be detected in a hair follicle test, as these tests are designed to detect long-term drug use. LSD use typically doesn’t leave a lasting trace in hair, making it an unreliable method for detection.

  3. <strong>How long does LSD stay in your urine?</strong>

    LSD is usually detectable in urine for a short period, typically 1-3 days after use. However, it’s essential to note that standard drug tests do not usually screen for LSD.

  4. <strong>Is it possible for LSD to show up in a blood test?</strong>

    LSD can be detected in blood shortly after use, typically within a few hours. However, its presence quickly diminishes, and it’s challenging to detect beyond 12 hours after ingestion.

  5. <strong>5. Does the frequency of LSD use affect detection times?</strong>

    Generally, the frequency of LSD use doesn’t significantly impact detection times. The body processes and eliminates LSD relatively quickly, regardless of how often it’s used.

  6. How do<strong> body weight and metabolism affect LSD detection times?</strong>

    Body weight and metabolism can influence how long LSD stays in your system to some extent. People with faster metabolisms may eliminate the drug slightly quicker, but overall, LSD tends to exit the body within a similar timeframe for most individuals.
