If you or a loved one is taking LSD (also known as acid) and are facing a drug test, chances are, it will show up on the test. In fact, the most common drug test administered at work, the urine test, is one of the easiest ways to detect LSD. At the same time, many drug tests simply don’t screen for LSD, in part because many of the people who use it do so in such tiny amounts that it’s difficult to detect anyway.
However, whether or not LSD shows up on a drug test depends a lot on factors like what kind of test it is, how long you’re tested after the last use, and how long and how much you’ve been using. Other factors like metabolism and body weight will also play a role. However, on average, if you do get a surprise drug test, the answer is “yes, LSD will show up IF they are testing for it”.
LSD shows up anywhere from a few hours to several months after your last usage. Here, visibility on a drug test normally depends on what kind of test you’re getting.
For example, most workplace drug tests use a simple urine screening. Here, you can expect LSD to show up 1-4 days after the last usage. For example, if your employer is doing a simple LSD strip test, it will only detect the drug for 1-3 days – but will show a positive result in about 5 minutes. On the other hand, a more extensive urine spectrum analysis will show LSD usage for up to four days after your last consumption.
That’s markedly different from other types of tests. For example, a blood test only shows LSD for about 6-12 hours after the last dose. That’s because the blood quickly purifies out the drug and metabolizes it into the liver and kidneys. By the time you’re no longer feeling the effects of LSD, it shouldn’t’ show up on a blood test. But, that doesn’t matter very much because blood tests are almost never used to detect drug use.
However, that rate of metabolism, known as “half-life” does mean that the more of a drug you take, the more likely it is to be present in your body for longer.
On the other hand, a hair or nails test could show LSD usage for as long as 90 days after your last usage. If you have very long hair, it could be even longer. Of course, most academic and workplace tests don’t use hair and nails either, but you may be asked to submit samples if you contest a positive urine test. At the same time, LSD is unreliably detectable in hair and nails in that it’s impossible to prove repeat use or when usage happened. In addition, because metabolites don’t appear in hair or nails, individuals often have to use over longer periods of time for LSD to show up reliably in hair at all.
Micro dosing or taking tiny doses, usually 20mg or lower, is a common form of self-medication, where people use LSD or another psychedelic drug to attempt to treat anything from substance use disorders to mental health problems. These tiny doses are just under the amount needed to create a psychedelic reaction (25mg in most humans). These amounts will be significantly harder to detect in standard drug tests.
However, over time, as you continue to use LSD, the metabolites LSD breaks down into will build up in the kidneys. Eventually, this becomes just as visible on a urine test as a larger dose of LSD would be.
It’s also more likely to trigger a positive result in a hair test, although it’s unlikely that your employer would ask for a hair test.
What does that mean if you’re microdosing? If you’ve been microdosing for some time, chances are very high that you’ll show up as positive for LSD usage.
There are many factors that influence whether LSD will show up on a drug test or not. The most important of these is the type of test. In addition you’ll have to consider:
Essentially, test results can vary and a great deal.
“Normal” LSD dosing includes a few micrograms, typically 10-20 for a micro-macro dose and 100-200 for a dose intended to get someone high. That’s as little as 0.2% of a normal dose of MDMA or 0.005% of a dose of psilocybin. The tiny doses needed to produce an effect make LSD difficult to test for, simply because the test has to be extremely sensitive in order to work at all.
For that reason, most LSD tests are conducted using gas chromatography-mass spectrometry in a lab. If your employer is paying to have drug samples tested in a lab rather than using immunoassays (strips that change color or indicate yes/no like a pregnancy test or covid antigen test), it’s more likely that you’ll get a positive result from even a tiny amount of the drug.
Eventually, if you’re using a drug and you know you shouldn’t, there’s probably something wrong. If you find yourself using despite knowing that it could put your work, career, or study in danger, you might need help. That’s also true if you’re using LSD to try to self-medicate another problem. Seeking out treatment including behavioral therapy can help you to build the skills to cope with and manage without using LSD or another substance.
While LSD is not highly addictive, it can be part of existing behavioral disorders and seeking behavior, it can be part of looking for an easy way out of another problem, and it can make your problems worse by increasing anxiety and mental health problems – without actually solving the root issue.

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 of 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 of 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), both for Windows and for MAC users.
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
