How Long Does LSD Stay In Your System, Effects, Health Risks, Drug Tests & Addiction Treatment
How Long Does LSD Stay In Your System
LSD (lysergic acid diethylamide) is a synthetic (man-made) drug that has been abused for its hallucinogenic
properties since the 1960s. If consumed in a sufficiently large dose, LSD produces delusions and visual hallucinations that distort the user’s sense of time and identity.
LSD (lysergic acid diethylamide), often called acid, is an illicit hallucinogenic drug that affects your perceptions for several hours and is detectable on drug addiction screening tests. The drug can be detected by urine, blood, and hair tests, but does not show up on standard saliva tests.
How Long Does LSD Last
The half-life of LSD is around 5.1 hours. The effects can last up to 12 hours. Research has found that peak levels following a single dose occur at a median of 1.5 hours after administration. After peaking, drug levels decline and reach half of the peak levels at approximately 3.6 hours after administration but the effects of the drug can last for up to 12 hours.
Once orally ingested, the substance is quickly absorbed through the gastrointestinal tract and mucous membranes. The drug reaches the bloodstream and organs quickly, about 10 to 15 minutes after being ingested. The drug is primarily processed by the liver, where it is metabolized into a number of other inactive metabolites.
Within 24 hours, almost all the drug has been metabolized and excreted. Approximately 13% of the drug is eliminated as a metabolite 2-oxo-3-hydroxy-LSD (O-H-LSD). Research suggests that this byproduct is present in urine samples at concentration levels 16 to 43 times higher than LSD. Researchers have attempted to develop different methods for detecting LSD, but the fact that the drug is unstable, broken down so quickly, and usually taken in relatively small amounts presents challenges. 
The effects associated with LSD use are unpredictable and depend upon the amount taken, the surroundings in which the drug is used, and the user’s personality, mood, and expectations. Some LSD users experience a feeling of despair, while others report terrifying fears—of losing control, going insane, or dying. Some users have suffered fatal accidents while under the influence of LSD. LSD users often have flashbacks, during which certain aspects of their LSD experience recur even though they have stopped taking the drug. In addition, LSD users may develop long-lasting psychoses, such as schizophrenia or severe depression.
Is LSD addictive? LSD is not considered an addictive drug—that is, it does not produce compulsive drug-seeking behavior as cocaine, heroin, and meth effects do. However, LSD users may develop tolerance to the drug, meaning that they must consume progressively larger doses of the drug in order to continue to experience the hallucinogenic effects that they seek.
How Long Do The Effects Last
LSD is usually swallowed as a capsule or liquid or absorbed in your mouth on a paper square. Users feel the effects of LSD 20 to 90 minutes after taking a dose, peaking at two to four hours, and diminishing over six to eight hours.
How Long Does It Take For LSD To Kick In
While on an LSD acid trip, people can have rapid emotional shifts, intensified and distorted sensory experiences, and changes in the perception of time. If a large dose of LSD is taken, it can produce some very unpleasant effects, sometimes called a “bad trip.” But some people can experience a bad trip no matter how much they consumed.
In addition to sensory and mood effects, LSD use may also result in:
- Dry mouth
- Elevated body temperature
- Increased blood pressure
- Increased heart rate
- Loss of appetite
How Long Does LSD Stay In Your System
How long LSD can be detected in the body depends on the:
- Specific type of testing assay used
- Detection limit of the test (the cutoff levels being used for the substance)
- Point of collection
- Type of biological sample obtained for testing (e.g., urine, blood, hair)
- Amount of LSD taken prior to the test
- Individual factors, such as age, health, and weight
How Long Does LSD Stay In Urine
LSD can generally be detected in urine tests within eight hours of use and up to two to four days after use.
How Long Does LSD Stay In Your Blood
In one study, researchers found that LSD was detectable in blood samples taken 16 hours after participants had been given 200mcg of LSD. For those given a smaller dose of 100mcg, researchers were able to detect the substance in blood tests 8 hours after administration. Because levels decline steadily over time, the ability to detect the substance dropped considerably after the 16-hour mark. 
How Long Does LSD Stay In Your Saliva
Oral fluid tests are not the most common means of testing for drugs. They are, however, good for checking recent drug use. But LSD does not show up on regular saliva tests.
How Long Does LSD Stay In Your Hair
LSD, like many other drugs, can be detected with a hair follicle drug test for up to 90 days. However, the use of hair testing is relatively rare. Because the drug is often taken at such low doses, it can be very difficult to detect in both research and forensic settings. While hair tests may occasionally be used to check for LSD, they tend to be costly and their results may be unreliable.
Some people who use LSD report having bad trips and lasting emotional effects. There’s no surefire way to know whether your trip will be good or bad, but your risk of experiencing longer-lasting effects, such as flashbacks, increases when you take a high dose or use it often.
Using LSD frequently or in large amounts also increases your risk of developing a tolerance or psychological addiction to it. It can also increase your risk of a rare condition called hallucinogen persistent perception disorder. Keep in mind that LSD can have extremely powerful effects that can alter your perception and judgment. This might make you more likely to take risks or do things you otherwise wouldn’t.
LSD Drug Test
There are several things that can affect how long acid is detectable in an LSD drug test. These include:
- Your body composition. Your height and amount of body fat and muscle plays a role in how long acid is detectable. The more fat cells a person has, the longer drug metabolites linger in the body. Body water content also matters. The more you have, the faster the drug is diluted.
- Your age. Your liver function and metabolism slows with age. Younger people metabolize acid faster than older adults.
- Your liver function. Your liver plays a key role in metabolizing acid. If you have a medical condition or take a medication that impairs your liver function, LSD will be harder to eliminate.
- Time between use and testing. Acid is eliminated from the body quickly, which makes it hard to detect. The sooner the LSD drug test is performed after acid is taken, the more likely it is to detect it.
- How much you take. The more you take, the longer it will be detectable. How often you take it can also affect detection time.
- Your metabolism. The faster your metabolism, the faster acid leaves your system. 
Is LSD Addictive?
LSD is illegal. LSD is a Schedule I substance under the Controlled Substances Act. Schedule I drugs, which include heroin and MDMA, have a high potential for abuse and serve no legitimate medical purpose. 
LSD Addiction Treatment
We Level Up TX specializes in substance addiction like narcotics, alcohol, shrooms, LSD, and other psychedelics. It is highly advisable that you know how long does LSD stay in your system and how they are dangerously addictive; and that there are available treatments too for this type of addiction.
Clients in detox level of care focus on medical stability. They meet with medical staff daily along with nursing staff several times throughout the day. Client Med pass occurs four times per day where they sit with nursing staff and receive detox progress evaluation with their vitals and the provision of prescribed medications. Once clients are medically stable, they progress to the residential level of care. At this level of care, clients now see medical staff twice per week (unless required more often), and they must attend group therapy sessions.
If someone has combined LSD with other substances like alcohol, benzodiazepines, stimulants, or opioids, detox is needed for recovery. Summarily, detox would help the person using multiple drugs stop further addiction to other substances before they worsen. In addition, detox would include cutting-edge medication to cleanse the body of harmful substances with polydrug use. Contact a treatment provider to explore these treatment options.
