LSD, commonly known as acid, is a potent hallucinogenic drug that can remain in the body for varying lengths of time depending on the type of drug test used. If you’re wondering “does LSD show up on a drug test?”, the answer depends on multiple factors, including metabolism, dosage, frequency of use, and the type of test performed. Unlike more commonly screened substances such as marijuana or cocaine, LSD is not always included in standard drug tests, but specialized tests can detect LSD in urine, blood, and hair samples for different durations.
LSD is metabolized primarily into 2-oxo-3-hydroxy-LSD, which has a longer detection window than LSD itself. This metabolite plays a crucial role in how long LSD stays in your system and whether it can be detected through drug testing.
LSD’s presence in the body depends on various factors, including metabolism, dosage, frequency of use, and overall health. When someone takes LSD (acid), the body rapidly absorbs the drug, and it begins affecting the brain within 20 to 90 minutes. The half-life of LSD is approximately 3.6 hours, meaning that in that time, the body eliminates half of the ingested dose. However, traces of LSD and its metabolites can persist far longer, making it detectable in different types of LSD drug tests.
The type of drug test significantly impacts how long LSD stays in your system. Urine tests for LSD are among the most common, and they can detect LSD metabolites for one to four days after use. However, in individuals who take higher doses or frequently microdose LSD, these metabolites can linger in urine longer, increasing the chances of a positive LSD urine test. Blood tests for LSD, on the other hand, have a much shorter detection window, typically identifying LSD in the bloodstream for about six to twelve hours. Since LSD is quickly metabolized by the liver, it exits the blood rapidly, making blood tests for LSD less reliable for detecting past use.
For those undergoing hair drug testing for LSD, the detection window is significantly longer. Unlike urine or blood tests, LSD in hair follicles can be detected for up to 90 days after last use. This method is less commonly used, but it may be requested in probation drug tests, forensic investigations, or workplace screenings where long-term substance use is a concern. However, hair tests for LSD are not always reliable because metabolite levels in hair samples can vary based on hair growth rate, color, and individual differences.
While saliva tests for LSD are rare, some laboratories have explored the possibility of detecting LSD in saliva samples. However, due to LSD’s rapid metabolism and low concentration in saliva, this method is not widely used or considered highly effective.
Ultimately, LSD drug test detection times vary based on the individual and the type of screening used. If someone is worried about LSD staying in their system, it’s important to consider factors like dosage, frequency of use, hydration, and metabolic rate. While acid may only stay in the bloodstream for hours, its metabolites can persist in urine and hair for days or even months, depending on the test. Whether you’re preparing for a workplace drug screening, probation drug test, or medical examination, understanding how long LSD stays in your system can help you make informed decisions.

LSD does not typically appear on standard 5-panel or 10-panel drug tests, which focus on substances like marijuana, cocaine, opioids, amphetamines, and PCP. However, specialized LSD drug tests, such as enzyme immunoassay (EIA) or gas chromatography-mass spectrometry (GC-MS), can detect LSD in urine or blood.
Urine tests are the most common method for LSD drug testing. LSD can be detected in urine for 1 to 4 days after use. However, chronic users or those taking large doses may test positive for a longer period.
LSD remains in blood for only 6-12 hours, meaning that a blood test for LSD will likely be negative after a day unless taken shortly after use.
LSD can be detected in hair follicle tests for up to 90 days, but these tests are rare due to the low concentration of LSD in hair samples.
Microdosing LSD, or taking very small doses (typically 5-20 micrograms), has gained popularity for alleged cognitive benefits. While microdosing results in lower drug concentrations, repeated use can cause a buildup of LSD metabolites, making it detectable in urine and hair tests.
If you microdose LSD regularly, you could test positive on an LSD urine test or hair screening.
Most standard workplace drug tests do not include LSD testing. However, some employers and legal settings may use specialized LSD tests. These tests are typically used when psychedelic drug use is suspected.
Probation and legal drug tests may include LSD screening, particularly if there is a history of psychedelic use. In such cases, specialized LSD urine tests or hair analyses may be conducted.
Home drug tests rarely screen for LSD. However, laboratory-based urine or hair follicle tests can provide accurate LSD detection results.
While LSD is not considered physically addictive, regular use can lead to psychological dependence, persistent hallucinations, and hallucinogen persisting perception disorder (HPPD). If you or a loved one is struggling with LSD use, professional treatment can help address underlying issues and develop healthier coping mechanisms.

If you’re using LSD and feel it’s affecting your career, health, or relationships, it may be time to seek help. Sometimes, people use substances to cope with deeper issues, which can worsen over time. Behavioral therapy, counseling, and support networks can help you address these root problems without relying on substances.
While LSD isn’t typically classified as addictive, it may contribute to or worsen mental health challenges, increase anxiety, or serve as an unhelpful coping mechanism.
At Asana Recovery, we offer a range of treatment options, including detox, residential, and outpatient programs, to support those dealing with substance use.

LSD does not typically appear on standard drug tests, such as 5-panel or 10-panel screenings. However, specialized LSD drug tests, including enzyme immunoassays (EIA) and gas chromatography-mass spectrometry (GC-MS), can detect LSD in urine, blood, and hair samples. These tests are less common but may be used in probation drug testing, legal cases, or forensic investigations.
The length of time LSD stays in the system varies based on factors like dosage, frequency of use, metabolism, and body composition. On average:
Since acid is quickly metabolized, LSD drug tests usually focus on detecting its metabolites, particularly 2-oxo-3-hydroxy-LSD, which can remain in the system longer.
If a urine test for LSD is conducted, the drug is typically detectable for 1 to 4 days after use. However, individuals who microdose LSD or take high doses may have LSD metabolites in their urine for a longer period. Factors like hydration, kidney function, and overall health can also affect how long LSD stays in urine.
Yes, LSD can be detected in a hair test for up to 90 days after use. However, hair drug tests for LSD are not commonly used in standard workplace screenings because LSD concentrations in hair follicles are much lower compared to other drugs. Hair tests are more often utilized in forensic settings or legal investigations.
Yes, but only for a short period. LSD in blood can be detected for approximately 6 to 12 hours after ingestion. Since LSD is rapidly metabolized by the liver, blood drug tests for LSD are rare and are generally only effective if conducted soon after use.
Probation drug tests may include LSD testing, depending on the individual’s legal requirements and history of substance use. While most standard probation drug tests do not screen for LSD, a specific test for LSD could be requested if LSD use is suspected.
Most home drug tests do not include LSD screening, as LSD testing requires more advanced laboratory methods. If an individual needs to test for LSD, they would need to use a lab-based urine, blood, or hair test that can detect LSD metabolites.
The effects of LSD typically last between 9 to 12 hours, depending on dosage and individual sensitivity. Users may experience:
“How long does an LSD trip last?” is a common question, and while most effects fade after 12 hours, some residual mental effects (such as visual disturbances or mood changes) can last several days.
Yes, microdosing LSD can result in a positive drug test. While individual microdoses are small, frequent use can cause LSD metabolites to accumulate, making urine and hair drug tests more likely to detect LSD use. Hair tests for LSD are particularly sensitive to repeated microdosing over time.
While the body naturally metabolizes LSD, some factors can help speed up the process, such as:
However, there is no guaranteed way to immediately remove LSD from your system, and drug tests can still detect LSD metabolites based on their specific detection windows.

We firmly believe that the internet should be available and accessible to anyone, and are committed to providing a website that is accessible to the widest possible audience, regardless of circumstance and ability.
To fulfill this, we aim to adhere as strictly as possible to the World Wide Web Consortium’s (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at the AA level. These guidelines explain how to make web content accessible to people with a wide array of disabilities. Complying with those guidelines helps us ensure that the website is accessible to all people: blind people, people with motor impairments, visual impairment, cognitive disabilities, and more.
This website utilizes various technologies that are meant to make it as accessible as possible at all times. We utilize an accessibility interface that allows persons with specific disabilities to adjust the website’s UI (user interface) and design it to their personal needs.
Additionally, the website utilizes an AI-based application that runs in the background and optimizes its accessibility level constantly. This application remediates the website’s HTML, adapts Its functionality and behavior for screen-readers used by the blind users, and for keyboard functions used by individuals with motor impairments.
If you’ve found a malfunction or have ideas for improvement, we’ll be happy to hear from you. You can reach out to the website’s operators by using the following email
Our website implements the ARIA attributes (Accessible Rich Internet Applications) technique, alongside various different behavioral changes, to ensure blind users visiting with screen-readers are able to read, comprehend, and enjoy the website’s functions. As soon as a user with a screen-reader enters your site, they immediately receive a prompt to enter the Screen-Reader Profile so they can browse and operate your site effectively. Here’s how our website covers some of the most important screen-reader requirements, alongside console screenshots of code examples:
Screen-reader optimization: we run a background process that learns the website’s components from top to bottom, to ensure ongoing compliance even when updating the website. In this process, we provide screen-readers with meaningful data using the ARIA set of attributes. For example, we provide accurate form labels; descriptions for actionable icons (social media icons, search icons, cart icons, etc.); validation guidance for form inputs; element roles such as buttons, menus, modal dialogues (popups), and others. Additionally, the background process scans all the website’s images and provides an accurate and meaningful image-object-recognition-based description as an ALT (alternate text) tag for images that are not described. It will also extract texts that are embedded within the image, using an OCR (optical character recognition) technology. To turn on screen-reader adjustments at any time, users need only to press the Alt+1 keyboard combination. Screen-reader users also get automatic announcements to turn the Screen-reader mode on as soon as they enter the website.
These adjustments are compatible with all popular screen readers, including JAWS and NVDA.
Keyboard navigation optimization: The background process also adjusts the website’s HTML, and adds various behaviors using JavaScript code to make the website operable by the keyboard. This includes the ability to navigate the website using the Tab and Shift+Tab keys, operate dropdowns with the arrow keys, close them with Esc, trigger buttons and links using the Enter key, navigate between radio and checkbox elements using the arrow keys, and fill them in with the Spacebar or Enter key.Additionally, keyboard users will find quick-navigation and content-skip menus, available at any time by clicking Alt+1, or as the first elements of the site while navigating with the keyboard. The background process also handles triggered popups by moving the keyboard focus towards them as soon as they appear, and not allow the focus drift outside it.
Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
We aim to support the widest array of browsers and assistive technologies as possible, so our users can choose the best fitting tools for them, with as few limitations as possible. Therefore, we have worked very hard to be able to support all major systems that comprise over 95% of the user market share including Google Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS and NVDA (screen readers).
Despite our very best efforts to allow anybody to adjust the website to their needs. There may still be pages or sections that are not fully accessible, are in the process of becoming accessible, or are lacking an adequate technological solution to make them accessible. Still, we are continually improving our accessibility, adding, updating and improving its options and features, and developing and adopting new technologies. All this is meant to reach the optimal level of accessibility, following technological advancements. For any assistance, please reach out to
