Do shrooms show up on a drug test? This is a frequently asked question. While the duration of shroom effects is 3 to 6 hours, the length of time the shrooms remain in your system depends on how much you consume, your body composition, and several other factors.

This article will explain if shrooms show up on drug tests, and how long it will show in hair, blood, and urine.

What are Shrooms?

Magic mushrooms (commonly known as shrooms or mushrooms) are psychoactive fungi that contain psilocybin or psilocin. Psilocybin is a psychedelic substance. You can consume shrooms in a number of ways, including orally as a capsule or a powder, nasally, or intravenously. Powdered psilocybin can be mixed with fruit juice or steeped in tea. Mushrooms are also added to cooked food or fruit juice in order to enhance their flavor.

Psilocybin mushrooms are considered a Schedule I substance under the Controlled Substance Act in the United States. Due to its illegal nature, individuals may be charged with a fine or even go to prison if they are caught selling or carrying mushrooms.

Some mushrooms that appear to be psilocybin mushrooms are, in fact, poisonous. You may suffer severe liver damage or even death if you consume a poisonous mushroom. It is essential to understand the difference between poisonous mushrooms and psilocybin mushrooms to avoid the dangerous consequences. 

How Long Do Shrooms Last After Consumption?

The effects of psilocybin mushrooms typically last for about 4-6 hours, with the peak effects, or the “trip,” lasting for 2-3 hours. However, the exact duration can vary depending on the dose taken, the individual’s metabolism, and the method of ingestion.

It’s also important to note that the effects of shrooms can vary in intensity and may be influenced by external factors like the environment, mood, and mindset of the user. Some people may experience lingering effects, such as changes in mood or perception, for several hours after the main effects have worn off.

It’s recommended that individuals who choose to use shrooms do so in a safe and controlled environment, with a trusted individual to monitor them during the experience. Considering the potential risks before using shrooms is essential, as they can negatively affect mental health and well-being.

Do Shrooms Show Up On A Drug Test?

Yes, shrooms can show up on a drug test. A lot of standard panel tests don’t look for shrooms, but there are certain ones that do. These substances are processed by the body in a relatively fast manner. In certain situations, a person may have to take a hallucinogen test, for example, if they seem to be under the influence of these substances at the time.

There might also be a danger of magic mushrooms becoming contaminated by other detectable substances. A dishonest vendor might contaminate regular mushrooms with other chemicals, which a drug panel test may subsequently identify.

shrooms can show up in blood, urine, saliva, and hair tests within 24 hours of ingestion.

How Long do Shrooms Stay in Your System?

According to a review of research from 2021, shrooms can barely be detected in blood or saliva tests six hours after consumption. Therefore, it is unlikely that a test taken within a few hours of consumption would detect them.

  1. Urine test: Psilocybin can be detected in urine for up to 24-48 hours after ingestion. However, heavy or frequent use may result in detection for up to several days. The detection time can vary based on the sensitivity of the test used and the amount of psilocybin consumed.
  2. Blood test: Psilocybin is typically detectable in the blood within 30 minutes after ingestion and can remain detectable for up to 24 hours. However, the detection time may be shorter in some cases.
  3. Hair test: Psilocybin can be detected in hair up to 90 days after ingestion. However, the detection time may vary based on several factors, such as the length and color of the hair, the amount of drug used, and the frequency of use.
  4. Saliva test: Psilocybin can be detected in saliva for up to 24 hours after ingestion. However, the detection window may vary based on the sensitivity of the test used and the amount of psilocybin consumed.

How Long Do Drug Test Results Take?

If your sample was sent to a lab, negative results take 1-2 business days to come back after the testing lab receives the sample. However, if further testing is necessary, the confirmation process may take an extra day or two. Positive results may take longer, typically 4-6 days, as they require repeated testing to confirm drug use.

What Affects Detection?

The duration for which shrooms stay in your system can vary significantly based on various factors, some of which are beyond your control. These factors contribute to the variability in how long the effects of shrooms are felt and how they are metabolized and eliminated from the body. These factors include the time of the last dose, the method of use, the type of mushroom consumed, the user’s age, what they last ate, and their body composition. 

The Time of Last Dose

Hallucinogens like psilocybin are eliminated from the body rapidly. While the right drug test might help detect shrooms, the timing between ingestion and testing could be problematic. Drug tests that can detect shrooms or other substances after ingestion have a higher probability of succeeding if the test is taken quickly.

Method of Use

Whether you consume shrooms, dried or fresh, in a burger or tea, the method you consume your dose affects its potency and how quickly it passes through your body.

The Type of Mushroom

There are between 75 and 200 different psilocybin-containing mushroom species. The psilocybin content in mushrooms varies from mushroom to mushroom. The longer a shroom stays in the body, the more psilocybin it contains.


Psilocybin gets trapped in your body as your metabolism, kidney, and liver functions slow with age. Other substances behave similarly. As you get older, shrooms tend to stay in your body for longer.

What’s in Your Stomach

The speed at which psilocybin passes through your digestive system is affected by the quantity of food and liquid present in your stomach when you take the mushrooms. If there is a lot of food in your stomach when you take shrooms, they will take longer to move through your digestive system. Hydration speeds up the excretion of psilocybin.

Your Body

When you combine shrooms with other substances, you may experience severe side effects or remain in your system for longer than usual. Drinking alcohol or taking other substances with shrooms could alter how your body digests them. The other substance may be detected on a drug test even if the shrooms themselves aren’t, as well as the possibility that they’re mixed with another substance.

How to Get Shrooms Out of Your System Quickly

The effects of shrooms are not something you can flush out of your system quickly. However, there are some ways to move the process along. Drinking water can assist shroom metabolites to move through your system quicker, but not enough to make a significant difference if you’re trying to remain undetected. Your best option is to forgo shrooms as soon as possible if you’re worried about being detected.
